一般描述
The prepacked, disposable plastic guard cartridge retains unwanted materials that can harm your analytical column. Used in a wide range of applications, the HPLC guard cartridge system offers high efficiency, convenience, and cost savings. These cartridges fit into either of two reusable guard cartridge holders. The Integral system attaches directly to and becomes an integral part of a WVS HPLC column, requiring no connecting tubing. Because of this, there is virtually no loss in efficiency.
The Universal system can be used with any standard analytical column, bringing guard cartridge convenience to traditional HPLC columns.
Guard cartridges are available in four phases: silica, reversed phase, anion exchanger, and cation exchanger.
Zero-Dead-Volume
Guard columns offer protection by trapping unwanted compounds that would otherwise be strongly retained on the HPLC column. One of the problems inherent with other guard columns is that they either contribute too much dead volume or add to the analysis times of the separation (especially in short, high speed columns). Whatman has overcome this by developing a zero-dead-volume HPLC guard cartridge system which eliminates almost all extra void volume and does not detrimentally affect the separation.
