tography Detector System enables you to make quantitative analyses of high molecular weight compounds without the need for time-consuming preparation of derivatives. "Pre-flame" Pyrolysis, a unique feature of this new, patented system, transforms liquid chromatography solutes into a gaseous state in a controlled atmosphere furnace before they reach the hydrogen flame detector. Because the conve...

Formaldehyde is a chemical used in many different industrial sectors and classified as carcinogen well causing allergic reactions. Due to the health effects of formaldehyde, which widely textile dyes auxiliary chemicals, its analysis this type matrices becomes important. In study, order meet these requirements, formaldehyde was converted oxime derivative by derivatization with o-(2,3,4,5,6-Pent...

Residual solvents in pharmaceutical samples are monitored using gas chromatography with head space. Based on good manufacturing practices, measuring residual solvents is mandatory for the release testing of all active pharmaceutical ingredients (API). The analysis of residual organic solvents (methanol, acetone, cyclohexane, dichloromethane, toluene) in Omeprazole, an active pharmaceutical ingr...
