Flash Chromatography

Flash chromatography is a purification technique that is designed for rapid separation by using air pressure as opposed to slow and inefficient gravityfed chromatography. It differs from the conventional column technique by using slightly smaller silica gel particles and pressurized gas at 50–200 psi.

Market Profile: Volatile Organic Extraction

Gas chromatography (GC) sampling of volatile organic compounds (VOCs) is typically done by headspace, purge and trap, or thermal desorption instruments. Headspace sampling is the simplest of the techniques, where a vapor sample is taken from the space above the liquid sample in a GC vial.

Chinese Laboratories Share Views in Survey

For high performance liquid chromatography (HPLC), ultrahigh-pressure LC (UHPLC), and LC–mass spectrometry (LC–MS) technologies, China has continued to provide solid growth opportunities, as a result of the country’s investments in the pharmaceutical industry, as well as agriculture and food testing.
