Filtration is simple, versatile, and necessary to prevent clogging of valuable HPLC columns. Captiva 0,2 μm and 0,45 μm depth filter plates are ideal for filtering samples prior to LC/MS injection. Captiva 10 μm glass fibre filter plates are designed for clarifying highly particle-laden samples, such as freshly thawed plasma and hepatocyte filtration, preventing sample transfer problems from pipette tip clogging. They are perfect for automated systems and for use with DuoSeal 96 96-well seals.

Bond Elut™ LMS polymeric sorbent lets you elute without having to add amine modifiers, buffers, or acids. The elimination of secondary interactions means that elution of analytes can be achieved with pure organic solvents or HPLC mobile phase-compatible solvent mixtures of low ionic strength. These characteristics are crucial to allow compatibility with LC/MS or other delicate analytical techniques.

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.

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.
