The application scope of high performance liquid chromatograph is expanding day by day. Because it uses a non-destructive detector, after the sample is analyzed, in most cases, the mobile phase can be removed to recover a small amount of precious samples, and it can also be used for sample purification and preparation.

Performance characteristics of lab high performance liquid chromatograph

1. High separation efficiency

Due to the use of new high performance particulate stationary phase packing, the write off of liquid chromatography packing column is much higher than that of gas chromatography packing column.

2. High detection sensitivity

Most detectors used in high performance liquid chromatograph have high sensitivity.

3. Fast analysis

Due to the use of the high-pressure infusion pump, compared with the classical liquid chromatography, the analysis time is greatly shortened. When the infusion pressure increases, the flow rate of the mobile phase will speed up, and it only takes a few to dozens of minutes to complete the analysis of a sample.

4. High selectivity

The liquid chromatographic column has high column efficiency, and the mobile phase can control and improve the selectivity of the separation process. Therefore, high performance liquid chromatography can not only analyze different types of organic compounds and their isomers, but also analyze optically active isomers with very similar properties, and has played an important role in the production control analysis of highly effective synthetic medicine and sublimation medicine.
