HPLC Guard Columns and Cartridges
Perkin Elmer US LLC Brownlee Spheri-5 RP-8 Cartridge Column - 220 mm x 4.6 mm I. D.
Monofunctional bonded C8 phase for general purpose reversed phase small molecule applications.
Perkin Elmer US LLC Brownlee Aquapore ODS RP-18 NewGuard Cartridge - 15 mm x 3.2 mm I.D., Pkg. 3
Aquapore ODS RP-18 NewGuard cartridges are based on a spherical silica support suitable for the separation of large biopolymers. These cartridges prolong column life by 2 to 5 times while protecting columns from particulates and strongly bound sample components. Actual bed length of each 15 mm NewGuard is approximately 13 mm. These NewGuard Cartridges require a holder: To couple with a conventional column - NewGuard Holder (07150001) To couple with an MPLC cartridge - Union (07150018) Quantity: Package of 3 Interaction Mode: Reversed Phase USP Code: L1
Metrohm USA METROSEP A SUPP 4/5 GUARD
The Metrosep a Supp 4/5 Guard/4.0 reliably protects the Metrosep a Supp 4, 5 and 7 IC anion columns against contamination from the sample or the eluent. It contains the same separation material as the Metrosep a Supp 5, is also made of PEEK, and is screwed directly onto the respective separation column with nearly no dead volume ( in.On Column Guard System in.). The guard column prolongs the service life of the analytical column, with practically no influence on its chromatographic separating efficiency. The economical price and simple handling make using the a Supp 4/5 Guard/4.0 highly recommended.
Waters Corp ACQUITY UPLC CSH C18 VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
ACQUITY CSH C18 columns were designed to provide alternate selectivity compared to other reversed-phase UPLC columns. These ultra-efficient columns overcome peak shape asymmetry and poor loading capacity for basic compounds, column bleed, and rapid mobile-phase re-equilibration. The VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
Pickering Laboratories Inc SODIUM COLUMN 4X150MM
High-efficiency Sodium Cation-exchange Column for protein and collegen hydrolysates, 4.0 x 150 mm, includes Amino Acid Test Mixture 1700-0070 Amino Acid Analysis.
Waters Corp XTerra MS C8 VanGuard Cartridge, 125Å, 3.5 µm, 2.1 mm X 5 mm, 3/pk
XTerra MS C8 VanGuard Cartridges are used to extend analytical column lifetime and performance by removing particulate contamination from the mobile phase stream. This cartridge is optimized to protect all 2.1 mm and 3.0 mm I.D. XTerra MS C8 analytical columns containing 3.5 µm sorbent particles.
Sielc Technologies Inc Primesep 100 Guard column 4.6xG mm 5um, 100A
Primesep 100 is a mixed-mode analytical column with acidic ion-pairing groups embedded into long hydrophobic ligand chains.
