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.

How does HPLC (high performance liquid chromatography. HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC) 1. a) HPLC is an advance on column chromatography where the solvent is forced through the column at a very high pressure of up to 400 atmospheres. This makes the whole process much faster, but also allows you to use a much smaller particle size in the column. Why is that an advantage? b) There are two forms of HPLC – normal phase HPLC …, High Performance Liquid Chromatography (HPLC) is a widely used analytical technique that many industries and research fields rely heavily on.

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.
