  • solvent
  • It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. (wikipedia.org)
  • To maximise plasma temperature (and hence ionisation efficiency) and stability, the sample should be introduced through the central tube with as little liquid (solvent load) as possible, and with consistent droplet sizes. (wikipedia.org)
  • A nebuliser can be used for liquid samples, followed by a spray chamber to remove larger droplets, or a desolvating nebuliser can be used to evaporate most of the solvent before it reaches the torch. (wikipedia.org)
  • samples
  • Samples to be analyzed are introduced into this central channel, usually as a mist of liquid formed by passing the liquid sample into a nebulizer. (wikipedia.org)
  • Protein extraction from tissues with tough extracellular matrices (e.g., biopsy samples, venous tissues, cartilage, skin) is often achieved in a laboratory setting by impact pulverization in liquid nitrogen. (wikipedia.org)
  • Samples are frozen in liquid nitrogen and subsequently subjected to impact or mechanical grinding. (wikipedia.org)
  • centrifuge
  • The net effect of "spinning" the sample in a centrifuge is that massive, small, and dense particles move outward faster than less massive particles or particles with more "drag" in the liquid. (wikipedia.org)
  • When suspensions of particles are "spun" in a centrifuge, a "pellet" may form at the bottom of the vessel that is enriched for the most massive particles with low drag in the liquid. (wikipedia.org)
  • fractions
  • In order to eliminate the time and monitoring assorted with drip columns, fractions often equal to the full exclusion volume of the column are collected regardless of sample volume resulting in significant dilution of sample. (wikipedia.org)
  • pores
  • This requires the size of the pores to be smaller than the diameter of the two separate components. (wikipedia.org)
  • analyte
  • The analyte is the substance to be separated during chromatography. (wikipedia.org)
  • Analytical chromatography is used to determine the existence and possibly also the concentration of analyte(s) in a sample. (wikipedia.org)
  • Overall, the interface is a mechanically simple part of the LC-MS system that transfers the maximum amount of analyte, removes a significant portion of the mobile phase used in LC and preserves the chemical identity of the chromatography products (chemically inert). (wikipedia.org)
  • respiratory
  • For example, dry powder inhalation (DPI) for administering drugs to the respiratory tract require particles in a narrow size range (1-5 μm) to be effective. (diva-portal.org)
  • sample
  • The inlet flow is where the carrier liquid is pumped into the channel and it creates a parabolic flow profile and it propels the sample towards the outlet of the channel. (wikipedia.org)
  • Dialysis, on the other hand, is much less dependent on sample size as related to device format. (wikipedia.org)
  • particle
  • In a novel process which allows controlling of the particle size during the synthesis of palladium cuboctahedrons. (sigmaaldrich.com)
  • The tendency of a given particle to move through the liquid because of this force is offset by the resistance the liquid exerts on the particle. (wikipedia.org)
  • particles
  • Non-compacted particles remain mostly in the liquid called "supernatant" and can be removed from the vessel thereby separating the supernatant from the pellet. (wikipedia.org)
  • The breakthrough for large molecule laser desorption ionization came in 1987 when Koichi Tanaka of Shimadzu Corporation and his co-workers used what they called the "ultra fine metal plus liquid matrix method" that combined 30 nm cobalt particles in glycerol with a 337 nm nitrogen laser for ionization. (wikipedia.org)
  • high
  • For gel-type ion exchangers, selectivity reversal at very high ionic strength can also provide a solution. (wikipedia.org)
  • operate
  • While the mobile phase in a LC system is a pressurized liquid, the MS analyzers commonly operate under vacuum (around 10−6 torr). (wikipedia.org)
  • provides
  • Blue Devil provides film is used for autoradiography, Western blotting, sequencing, chemiluminescence and gel shift analysis. (wikipedia.org)
  • Poseidon provides ergonomic liquid handling equipment including precision pipettes and pipet controllers. (wikipedia.org)
  • range
  • The precipitated powders were amorphous, containing particulate aggregates in the size range 1-6 microm with 5-10% residual moisture content. (diva-portal.org)
  • range of Liquid chromatography to one trillion ( 12) J. Chromatogr. (ximicat.com)
  • From this basic principle many forms of FFF have evolved varying by the nature of the separative force applied and the range in molecule size to which they are targeted. (wikipedia.org)
