Abstract:
We have developed Ultra High−Speed Liquid Chromatograph Systems, LaChromUltra. In order to achieve high speed analyses by reverse phase chromatography, we use columns with 2−micrometer packing particles of silica gel. The columns have good properties of both high number of theoretical plates and high column permeability. LaChromUltra system is suitable for the columns. The system consists of gradient elution pumps and autosampler with high pressure resistance of 60 MPa, and several detectors with high speed response of 10 ms.
Keywords: ultra high−speed liquid chromatograph; 2−micrometer particle; reverse phase chromatography; number of theoretical plates; column permeability; high speed response.
