Beschreibung: Capitiva ND^Lipids is as simple and easy-to-use as a standard protein precipitation plate. The non drip (ND) 96-well filtration plate is specially designed to effectively remove phospholipids from biofluids. Captiva ND^Lipidsremoves lipids, proteins, surfactants and other matrix interferences from plasma extracts. Ion suppression is significantly reduced for enhanced sensitivity and precision during trace analysis. The depletion of lipid
compounds also gives you better peak shapes and reproducible retention times so that standard operating procedures are easily validated. In addition, the fast, in-well precipitation technology of Captiva ND^Lipids ensures high sample throughput and helps reduce instrument downtime, with virtually no need for method development on a wide range of analytes.

Beschreibung: The CP-Si™l line consists of a range of stationary phases which are based on a polysiloxane backbone. Functional groups are added to the polymer to introduce selectivity. Each polymer used for the CP-Sil line is manufactured in-house and is optimised to obtain highest degree of reproducibility.

Beschreibung: Polystyrene standards for many organic solvents either for conventional GPC column calibration or for calibrating light scattering and viscosity detectors that provide equidistant calibration points for greater accuracy.

Beschreibung: The water-wettable, hydroxylated exterior allows excellent flow, even with biological fluids. A gradient of polarity on the polymer surface shunts small analytes to the more hydrophobic centre of the polymer bead, where they are retained prior to the washing and elution steps. Plexa provides these performance enhancements due to a unique polymeric architecture with a non-retentive, hydroxylated, amide-free surface and a non-polar PS/DVB core for retaining small molecules.

Beschreibung: Bond Elut™ Certify II was developed specifically for the rapid and effective extraction of acidic drugs and metabolites from urine and other biological matrices. Certify II is a mixed-mode cartridge packed with non-polar C8 and strong anion exchange (SAX) sorbent. It has been optimised for acidic drugs such as 11-nor-delta-9-tetrahydrocannibinol-carboxylic acid, salicylic acid, ibuprofen, acetaminophen and other compounds that possess both non-polar and anionic characteristics.

Beschreibung: These columns permit a simple, one stage clean-up as part of a methodology to determine pesticides in many organic matrices. The higher molecular weight fractions such as lipids, polymers, natural resins and dispersed high molecular weight components are easily eliminated in the GPC analysis.
