Chromatography works because of differences in the properties of molecules in materials. Some molecules, like water, have polarity, so they act like little magnets. It is possible to obtain very satisfactory quantitative results from a liquid chromatography (LC) analysis by following an established method, preparing the samples, placing them on the LC system, and after they have been analyzed, processing the collected data.

FLUORESCENCE DETECTORS. Principles. Fluorescence detectors are probably the most sensitive among the existing modern HPLC detectors. It is possible to detect even a presence of a single analyte molecule in the flow cell. HPLC solvents are costly in comparison to gases used for GC analysis. In addition to cost of solvents the maintenance cost of High Performance Liquid Chromatography systems is also higher due to high pressures developed in pumps and columns. GC analysis in comparison is less costly and there is lesser maintenance cost.
