HPLC Guard Columns and Cartridges
Waters Corp Spherisorb C1 Guard Cartridge, 80Å, 5 µm, 4.6 mm X 10 mm, 3/pk
Spherisorb C1 columns are classified as USP L13 and are general purpose columns that contain trimethylsilane bonded to silica.
Waters Corp Spherisorb Amino (NH2) Guard Cartridge, 80Å, 5 µm, 4.6 mm X 30 mm, 3/pk
Spherisorb NH2 (Amino) columns contain a silica-based aminopropyl bonded sorbent. The column is listed as USP L8 and is used for anion-exchange, normal-phase and HILIC separations.
Waters Corp µBondapak Amino (NH2) Sentry Guard Cartridge, 125Å, 10 µm, 3.9 mm X 20 mm, 2/pk
If your method calls for µBondapak packings, there is only one µBondapak packing material. Many companies claim to have columns with µBondapak-like selectivity but not one has ever passed Waters stringent QC batch test. Waters set the standard for reproducible, high-performance chromatographic columns. Waters µBondapak columns are still the most widely referenced and requested columns in the world.
Perkin Elmer US LLC Brownlee NewGuard Cartridge Holder
This holder can be used to couple any NewGuard directly to any LC column.
Sepax Technologies Inc Sepax HPLC Column Proteomix RP-1000, 5 µm, Guard cartridge with holder, 2 x 10 mm
Proteomix RP packings are porous polystyrene divinylbenzene (PS/DVB) polymer resins with narrow-dispersed particle size distribution. The base matrix of the resin is made of highly cross-linked PS/DVB which functions as reversed phase for chromatographic separation. The phase structure is phenyl and substituted phenyl functional groups that enable hydrophobic interaction. These highly rigid resins are provided with the particle size selection of 5, and 10 µm. In comparison to silica based reversed phase media, Proteomix RP phases have advantages for biomolecule separations with wide pH range (1-14) and high thermal stability. At various column temperatures, the Proteomix RP phases offer special selectivity, high resolution separation with online mass spec analysis capability for proteins such as mAb (monoclonal antibody), ADC (antibody drug conjugate) and related protein fragments.

Waters Corp ACQUITY PREMIER CSH Phenyl-Hexyl VanGuard FIT Cartridge, 1.7 µm, 2.1 x 5 mm, 3/pk;
ACQUITY PREMIER CSH Phenyl-Hexyl VanGuard FIT Cartridge, 1.7 µm, 2.1 x 5 mm, 3/pk;
Mac-Mod Avantor Prevail Amino, 110 Å, 5 µm, 4.6 x 7.5 mm Guard Cartridges (3/pk)
Avantor Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. Avantor Prevail HPLC columns are silica based except for Prevail Carbohydrate ES. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes. Avantor Prevail HPLC columns are stable from highly organic to highly aqueous. Avantor Prevail HPLC columns are specialty phases for specific applications. Avantor Prevail HPLC columns provide excellent sensitivity with microbore and ELSD applications.
