Liquid Chromatography Column
GALAK chromatography focus on liquid chromatography products for over 10 years. GALAK chromatography column series are versatile media based on the silica-gel/PS-DVB substrate for reversed-phase chromatography. The spherical substrate has low metal-ion content (<20 ppm)，high specific surface area and good mechanical strength. With GALAK's unique chemical bonding technique, the chromatography column series has excellent stability of bonding and end-capping. chromatography column series meet the high requirements for analysis and preparative applications.
