magnetic separation | magnetic sorting

Cell separationis a powerful techniqueand an indispensable toolfor basic and clinicalresearchapplications.The heterogeneity of biological cell populations often necessitates separation of individual cell types for deeper investigation. Traditionally, cell separationiscarried out based on the physical properties of cells, such asadherence,size, density oraffinity to electrostatic or magnetic forces. Biochemical characteristics, such as expression of surface antigens, are also used for cell separation.

This cell separation technique utilizes the potential to label cell surface markers with magnetic beadtagged antibodies and the ability of a magnetic field to migrate the labeled particles from a distance.1This controlled migration by a magnetic force (magnetophoresis) is invaluable in separating heterogeneous cell populations and is the basis for magnetic-activated cell sorting (MACS). Cells can be separated by tube-based or column-based methods.2

Positive selectionselects the cells that need to becollected as the target population. The methodusesmagnetic particleswithantibodiestargeting a subpopulation of interestcovalently bound to their surface.Once placed withinthemagnet, targeted cells migrate towardthe magnet and are retained within the magneticfield while the unlabeled cells are drawn offand discarded.The targeted cells can then be collected andused in the desiredapplication after removalfrom the magnetic field.

Positive cell selections yield excellent results with respect to purity, recovery, and viability of selected cells. However, depending on the cell type being selected and the surface antigen being targeted by the particle, positive selections can result in cells becoming activated or otherwise functionally altered. Even though the probability of activation is low, this magnetic particle-induced activation may be an issue if you specifically require purified yet unstimulated cells. In that case, you should consider negative selection for your cell separations.

Inthisprocedure, all unwanted cells are first labeled with a cocktail containing monoclonal antibodies against antigens expressed bythem. After washing away unbound antibody, a second-step reagent is used to magnetically label these cells. The labeled cells migrate to themagnet leavingin suspensiona pure and untouched subpopulation of cells to becollected.Alarge percentage (>95%) of unwanted cell populations can be removedthrough negative selection.1

Enrichment of cells before sorting is very beneficial for obtainingfaster andbetter sorting results, especially for very rare cell populations. In this procedure, the cells of interest are firstenriched through negative selection. The process can remove 2080% of unwanted cells,thusenriching theuntouchedcell population of interestand enabling faster and more efficient cell sorting.

the 32 most important examples of evaporation | life persona

Evaporation is the process by which water changes its state from liquid to gas or vapor. Water boils at 212 degrees Fahrenheit or 100 degrees Celsius, but begins to evaporate at 32 degrees Fahrenheit or 0 degrees Celsius, only slowly. As the temperature increases, the rate of evaporation also increases.

The amount of evaporation depends on the temperature and the amount of water. For example, there is not much evaporation in the Sahara desert, but why? Although it can be extremely hot in the Sahara, there is only sand; There is not much water to be evaporated.

If the molecule of a liquid gains enough energy in the form of heat from the environment, then it becomes steam. Evaporation occurs on the surface of a liquid, not through the body or volume. When evaporation occurs, the vapor pressure is lower than the surrounding atmosphere pressure.

When it rains, city streets often form puddles of water that are easily observable, but with a very short duration. This is because the evaporation takes place and evaporates the water of these puddles turning it into steam.

Although this is a little more difficult to observe, the seas and oceans are constantly evaporating, which causes rain. The water rises to the clouds and causes them to be loaded, causing the precipitations.

The tea cools by giving as a product the steam emanating from the cup. This causes the heat to dissipate, and allow us to drink the tea. The hot molecules on the surface are evaporated, taking with them the heat.

Gasoline droplets vaporize as soon as they receive heat, mixing with hot gases in the combustion chamber. The caloric energy may also be received by the radiation emanating from any refractory chamber of the combustion chamber.

Evaporation is also used as a mechanism for obtaining energy, see nuclear plants or hydroelectric plants where evaporation plays a fundamental role in energy processes. As noted above, the steam causes the turbines to ignite releasing energy.

It should not be confused with boiling, because it requires an essential physical condition and a temperature above 100 degrees centigrade. However, evaporation can occur at temperatures ranging from 0 degrees to 100 degrees.

magnetic separation and characterization of vivianite from digested sewage sludge - sciencedirect

For the first time, vivianite was separated from sludge via a wet magnetic technique.The study focuses on the analysis of the extracted vivianite and recovered P.The product contains vivianite (5060%), organic matter (20%), quartz and siderite.Phosphorus was recovered and purified from vivianite through alkaline treatment.After purification, heavy metals are in line with P rock and future legislation.

To prevent eutrophication of surface water, phosphate needs to be removed from sewage. Iron (Fe) dosing is commonly used to achieve this goal either as the main strategy or in support of biological removal. Vivianite (Fe(II)3(PO4)2*8H2O) plays a crucial role in capturing the phosphate, and if enough iron is present in the sludge after anaerobic digestion, 7090% of total phosphorus (P) can be bound in vivianite. Based on its paramagnetism and inspired by technologies used in the mining industry, a magnetic separation procedure has been developed. Two digested sludges from sewage treatment plants using Chemical Phosphorus Removal were processed with a lab-scale Jones magnetic separator with an emphasis on the characterization of the recovered vivianite and the P-rich caustic solution. The recovered fractions were analyzed with various analytical techniques (e.g., ICP-OES, TG-DSC-MS, XRD and Mssbauer spectroscopy). The magnetic separation showed a concentration factor for phosphorus and iron of 23. The separated fractions consist of 5262% of vivianite, 20% of organic matter, less than 10% of quartz and a small quantity of siderite. More than 80% of the P in the recovered vivianite mixture can be released and thus recovered via an alkaline treatment while the resulting iron oxide has the potential to be reused. Moreover, the trace elements in the P-rich caustic solution meet the future legislation for recovered phosphorus salts and are comparable to the usual content in Phosphate rock. The efficiency of the magnetic separation and the advantages of its implementation in WWTP are also discussed in this paper.

functionalized magnetic nanoparticles for the separation and purification of proteins and peptides - sciencedirect

Functionalized magnetic nanoparticles are employed for purification of proteins.Magnetic nanoparticles are less toxic, good hostages, cheap and reusable.Metal ion affinity causes selective interactions between metals and proteins.Magnetic natural and synthetic polymers are widely used in proteins purification.Valuable proteins are purified from natural samples with high yields in this method.

Nanoparticles have been widely employed for different biomedical applications due to their remarkable chemical and physical properties. The surface of nanomaterials can be modified by functionalization to create a strong recognition and binding sites between biological macromolecules and the nanostructures. Scientists have used this fact in the purification and extraction of bio-macromolecules like proteins, especially using magnetic nanoparticles that can be manipulated by an external magnetic field. The functionalization agents have included synthetic and natural polymers, antibodies, biomolecules or zwitterionic materials, as well as different nanomaterials such as carbon-based nanomaterials and metal oxide nanoparticles. The binding with the target is directly influenced by the size, surface energy and charge of the particles. Hydrophobicity and hydrophilicity of the nanoparticles is another important consideration that affects the selective purification of proteins by decorated magnetic nanoparticles.

what is magnetic separation? (with pictures)

Magnetic separation is an industrial process where ferromagnetic contaminants are recovered from materials on the production line. Manufacturers use this to extract useful metal, separate recycling, purify materials, and perform a wide variety of other tasks. Manufacturers of magnetic separation equipment may have a range of products available for sale for different applications, including an assortment of sizes with strong and weak magnetic fields to attract different kinds of magnetic material.

The magnetic separator consists of a large rotating drum that creates a magnetic field. Materials enter the separator and fall out through mesh at the base if they are not magnetic. Sensitive particles respond to the magnetism and cling to the sides of the container. The drums can be used in continuous processing of materials as they move along the assembly line, or in batch jobs, where a single batch is run through all at once.

One common use for magnetic separation is to remove unwanted metal from a shipment of goods. Magnetic separation can help companies keep materials pure, as well as remove things like nails and staples that may have crept into a shipment. The equipment can also purify ores, separate components for recycling, and perform a variety of other tasks where metals need to be separated or isolated. Equipment can range in size from a desktop unit for a lab that needs to process small amounts of material to huge drums used in scrap metal recycling centers.

Manufacturers of magnetic separation equipment typically provide specifications for their products for the benefit of prospective customers. Consumers may need equipment that targets a specific range of metals, or could require large size or high speed capacity. It may be possible to rent or lease equipment for some applications, or if a factory wants to try a device before committing to a purchase. Used equipment is also available.

A gentler form of magnetic separation can be used for delicate tasks like removing magnetic materials from cremated remains or finds at an archaeological site. In these situations, a technician carefully moves a magnet over the material to pull out materials like staples and jewelry. At a crematorium, this is necessary before ashes are ground, as metal objects can damage the equipment. For archaeologists, it can provide a mechanism for carefully separating materials at a find and documenting the position and location of various objects as the archaeologist uncovers them on site or in a lab.

@allenJo - I do believe they use these systems in water treatment systems. I dont know the mechanisms used but it is used from what Ive heard. Water should give up its magnetic particles quite easily, I would think, since the metals are just floating about like flotsam and jetsam in the ocean.

@Charred - Those are two very good points, and I am sure that they are accounted for. The uses described in the article suggest scenarios where the metals are rather loosely fitting, so I think the cleanup job would be thorough. What I wonder about is if this process can be adapted to water treatment? Since magnetic separation systems can be used to sift through fluids, could they purify water as well? That seems to be an obvious application. Where I live the tap water has a lot of metals and so we generally dont drink it. I already have three metal fillings; I dont need more metal in my body.

I see two things here that are necessary for magnetic separation to work well. First, the metals must be easily dislodged from whatever material or goop they happen to be sitting in. Otherwise, theyll just remain stuck, and the separation will be less than effective in pulling out all the metals. Second, the magnetic drum separator itself must be sufficiently strong. I think thats obvious, and the second point is related to the first. If the separating device is not strong it wont dislodge the metals; but there may be situations where the device is strong, but the metals are just stuck and wont budge.
