Waters Corp Waters VanGuard Pre-column, CSH C18, 130Å, 1.7 μm, 2.1 mm X 5 mm
This CSH C18 VanGuard pre-column offers alternative selectivity for reversed-phase UPLC. It improves peak shape, loading capacity, and protects UPLC columns. Connecting directly to the column inlet, it withstands pressures up to 18,000 psi.
- Alternate selectivity for reversed-phase UPLC.
- Improves peak shape and loading for basic compounds.
- Reduces column bleed; enables rapid mobile-phase re-equilibration.
- Direct connection to column inlet minimizes extra volumes and leaks.
- Withstands UPLC pressures up to 18,000 psi.
- Ultra-low volume design (2.1 mm ID x 5 mm length).
- Utilizes CSH Technology for enhanced sample loadability.
- Maintains mechanical/chemical stability; offers superior peak shape.
- Ensures exceptional stability across pH range.

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.
