HPLC: Principle and Maintenance with ApplicationSayed Md MumtazMustaq AhmadYogesh Kumar
The HPLC methodology applied to the analysis of biological samples makes it possible for the identification of many metabolites. Samples from two human embryos culture medium were analysed byhigh-pressure liquid chromatography–mass spectrometry(HPLC–MS). They work on the principle that many microorgani...

Principle Variable Wavelength Detector (VWD) Forward optics design • Only the selected wavelength passes the flow cell and is detected by the sample diode • A part of the light beam is redirected to the reference diode • Reference signal is not influenced by the content of the flow ...
C.7.2 Eluent Degassing Methods You can degas eluents using any of the following methods: • In-line degassing • Heating • Vacuum sonication C 93 CC Vacuum Degassing An in-line vacuum degasser operates on the principle of Henry's Law to remove dissolved gases from the solvent. According...
Sodium benzoate can be used for both the abovementioned purposes: it can increase the solubility of active principle [7], and it can also be used as antimicrobial preservative [8,9] to inhibit the development of micro-organism. So, the assay of sodium benzoate is required in these cases fo...
