The HSS C18 SB (Selectivity for Bases) is an unendcapped, low-coverage C18 bonded-phase column that was designed specifically to provide increased silanophilic interactions. This results in an alternate selectivity compared to a high-coverage fully-endcapped C18 column, particularly for basic compounds.
Sep-Pak Amino Propyl (NH2) Plus Light cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in aqueous medium below pH 8. Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. These cartridges have a distinctive finned outer body and a reduced internal diameter, which results in an interstitial volume about one-third that of the corresponding Plus-style cartridge. This design allows you to elute fractions in a minimal volume to improve recoveries and reduce solvent consumption, a benefit especially for applications where samples are limited or where excessive dilution is a concern.

This method validation kit consists of three batches of XSelect HSS Cyano columns packed with three different batches of sorbent
The MassPREP on-line desalting column can effectively desalt proteins prior to LC-MS analyses. Because non-volatile salts (e.g., NaCl) can suppress ionization of intact proteins leading to poor detection sensitivity, it is important to remove or significantly minimize the introduction of these compounds into the mass analyzer. The reversed-phase phenyl material contained in MassPREP on-line column successfully “traps” proteins, allowing the salts to be washed to waste prior to protein elution into the mass spectrometer. With an optimized LC-MS method, cycle times as low as 4 minutes (for intact antibody) and 10 minutes (for reduced antibody) are achievable. NOTE: UPLC Intact Mass Analysis Application Kit** (Includes MassPREP Micro Desalting Column and ACQUITY Tubing Kit)
These vials are produced to tight dimensional tolerance for use in autosamplers.
XSelect HSS T3 VanGuard Cartridges are used to extend analytical column lifetime and performance by removing particulate contamination from the mobile phase stream.
The XBridge BEH C8 sorbent is less retentive compared to the XBridge BEH C18 sorbent. Anyone developing methods may prefer the speed offered by a less retentive column, while improving peak shape and chromatographic performance. The trifunctionally bonded sorbent offers you the widest usable pH range (1-12), superior low pH stability, and ultra-low column bleed.
