Popis: PBA is a unique sorbent consisting of a phenylboronic acid covalently linked to a silica gel surface. Covalent processes result in a higher retention to the sorbent surface than other mechanisms, resulting in superior clean-up. The boronate group has a high specificity for cis-diol containing compounds such as catechols, nucleic acids, low molecular weight proteins and carbohydrates.

Popis: 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.

Popis: Microsorb™ C18 is an octadecylsilane-covered silica that has been bonded using monofunctional bonding agents under optimised conditions. This material is then endcapped with trimethylsilyl groups to minimise nonspecific binding, maximise mass recoveries and improve peak shape.

Popis: The CP-Cyclodextrin-β-2,3,6-M-19 column separates many optical isomers that could not be analyzed previously.

Popis: Bond Elut™ PRS is a strong cation exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in non-polar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, a high ionic strength eluent must be used, and so the use of PRS is recommended for weaker cationic species such as pyridinium compounds.

Popis: Capitiva ND^Lipids je jednoduchá a snadno použitelná standardní proteinová srážecí destička. Bezkapková (ND) 96-jamková filtrační destička je speciálně navržena pro účinné odstranění fosfolipidů z biotekutin. Captiva ND^Lipidsodstraňují lipidy, proteiny, povrchově aktivní látky a další maticové interference z extraktů plasmy. Iontová suprese je značně snížena pro zvýšené citlivosti a preciznosti během stopové analýzy. Odtraněním lipidových sloučenin se
tvoří lepší tvary píků a retenční časy jsou reprodukovatelné, proto se tyto standardní provozní postupy snadno validují. Kromě toho, rychlá technologie srážení v jamkách Captiva ND^Lipids zajišťuje vysokou propustnost vzorků a snižuje prostoje přístroje, prakticky bez nutnosti vývoje metod na široké škále analytů.
