YMC-UltraHT Hydrosphere C18

Silica-based ODS

YMC-UltraHT series columns are 2µm materials specifically designed for high-speed and high-throughput analysis.  The UltraHT series has two product offerings: Pro C18 as our standard ODS, and Hydrosphere C18 for hydrophilic compounds.  Both show the same selectivity and superior peak shape as 3µm and 5µm Pro C18 and Hydrosphere C18 materials, so easy method transfer from conventional to ultra-fast LC is available without changing elution conditions.  This can all be achieved on a conventional HPLC so long as care is taken to minimize system volume.
