The liquid solvent (mobile phase) is delivered under high pressure (up to 400 bar or 300.000 torr) into a packed column containing the stationary phase. The high pressure is necessary to achieve a constant flow rate for reproducible chromatography experiments High performance liquid chromatography (HPLC) is basically a highly improved form of column liquid chromatography. Instead of a solvent being allowed to drip through a column under gravity, it is forced through under high pressures of up to 400 atmospheres. That makes it much faster Otherwise as in high performance liquid chromatography (HPLC), the presence of the bands are detected using other instrumental analysis techniques such as UV-VIS spectroscopy 1.

The company was one of the first in the cannabis and hemp industries to implement large scale separations of THC and CBD to produce tailored formulations with targeted THC-CBD ratios. Chromatography is a separations technique that. Frequently referred to simply as HPLC, this form of column chromatography is used frequently in biochemistry. The analyte is forced through a column by liquid at high pressure, which decreases the time the separated components remain on the stationary phase. Less time on the column then translates to narrower peaks in the resulting chromatogram and thence to better selectivity and sensitivity High Performance Liquid Chromatography Pumps and Eluent Reservoirs. There are two primary modes used for pumping the mobile phase through an HPLC system. Isocratic elution is used when the mobile phase will remain constant during a run, such as when the eluent is being recycled. Gradient elution systems are used when the composition of the eluent will change during separation. The detection.
