Xtimate Lactose-NH2 column uses a special bonding process to make the retention of lactose on the stationary phase more stable, resulting in an extremely low RSD value for the lactose peak area. It is a dedicated column for lactose as specified in the Chinese Pharmacopoeia, Volume IV.
Xtimate HPLC column derives its outstanding performance from a special hybrid partic le based technique, which coats a unique 5nm organic/inorganic polymer layer on the silica surface, so that the pH range is extended to 1.0-12.5. Xtimate column is designed for HPLC method development. Regardless of the types of mobile phase or high temperature, Xtimate HPLC column always has stable performance and long lifetime.
