GC Column InertCap ProGuard Pure-WAX, 30 m x 0.25 mm ID, 0.25 µm film, with 5 m ProGuard

InertCap ProGuard (Build-in Guard Column)
Guard columns and retention gaps are used widely in gas chromatography. Both of them are short (1-10 m) piece of uncoated deactivated fused silica tubing which are placed in-line between the GC injection port and the analytical capillary column. Guard column is to protect the analytical column from contamination, not allowing nonvolatile materials to reach the analytical column. Retention gap is to help focus the compounds in large volume injected from the inlet to a small band at the head of the analytical column. InertCap ProGuard is a"guard column built-in"analytical capillary column without the connection for such purposes. For this reason, now there is no need to worry about leakage and compounds adsorption.

InertCap Pure-WAX is a high polar column bonded polyethylene glycol. Based on newly developed inner treatment technology, InertCap Pure-WAX achieves the highest inertness among the market available columns. InertCap Pure-WAX is an optimal column for analyses of acidic compounds and basic compounds that commercially available WAX columns were not capable of analyzing.
