Preparation Note Prepared by the reaction of silica gel with n -octadecyltrichlorosilane. After hydrolysis of the unreacted chloro groups, hydroxyl groups are blocked with trimethylsilyl groups.

Parker Balston gas stations provide both UHP grade hydrogen gas and zero grade air for flame ionization detectors. The system is specifically designed to supply gas to FIDs and to support flame thermionic and flame photometric detectors.

Analysis Note Water absorption capacity (24 h, 80 % relative humidity): &#8805 20 % Loss on drying (140&#176C, 3 h): &#8804 10 %

Desiccant sachet 100 g (orange silica gel) is a drying agent with a large surface area and high absorption capacity that provides longer storage conditions. It also changes its color from orange to colorless after moisture absorption.
