Whatman* HPLC Guard Cartridge Systems

The prepacked, disposable plastic guard cartridge retains unwanted materials that can harm your analytical column. Features a zero-dead-volume which eliminates almost all extra void volume and does not detrimentally affect the separation. Used in a wide range of applications, the HPLC guard cartridge system offers high efficiency, convenience and cost savings.
The integral system attaches directly to and becomes an integral part of the void-sealing (WVS) replacement column and requires no connecting tubing. The universal system can be used with any standard analytical column, bringing guard cartridge convenience to traditional HPLC columns. The guard cartridge is available in five phases: silica, reversed phase, anion exchanger, cation exchanger and polar amino-cyano.
