HPLC is performed to separate organic and biological compounds. It is especially useful for low or non-volatile organic compounds, which cannot be handled with gas chromatography. In column chromatography, the sample is passed through a column with the help of gravity which takes more time for analysis of drugs but in HPLC sample is. who use information generated by HPLC but do not necessarily do chromatography themselves. A standard instrument of HPLC incorporates following components:. The Gas Chromatography/Mass Spectrometry (GC/MS) instrument separates chemical mixtures (the GC component) and identifies the components at a molecular level (the MS component). Retention of these compounds by reversed phase involves a combination of hydrophobic and van der Waals type interactions between each. The HPLC method is very reliable mainly because of its ability to effect rapid separation and the high resolution achieved. The targeted compounds and internal standards are isolated from whole blood, serum, plasma, urine and other biological samples or evidenceby the use of liquid-liquid extraction (LLE). Fluorescence detectors are probably the most sensitive among the existing modern HPLC detectors. The nitrogen content is then measured by passing the remaining. •Light passes through a transparent low volume "flow cell" where the variation in light by UV Absorption, fluorescent emission, or change in refractive index are monitored and integrated to display Retention Time and Peak Area. For example, a molecule with a pI of 8. High performance liquid chromatography of plasma aminoacids using orthophthalaldehyde derivatisation. The HPLC column should be washed for at least half an hour after each run.
