CommaSil® SCX

CommaSil®Liquid Chromatography Columns’ sorbents are all made of ultra-pure porous spherical silica gel, which has good mechanical strength, uniform pore and particle size distribution range, and excellent variation and stability. The columns are mainly used in food testing and pharmaceutical industry, and can be applied to different instruments of HPLC and UPLC.

Features

● Superior selectivity and separation capability
● Excellent repeatability among batches
● Excellent chromatographic peak shape
● Perfect spherical silica with narrow particle size distribution
● Extremely strong mechanical strength, long shelf life.
● Good acid and alkali resistance
