Market Profile: UHPLC versus Standard HPLC

Here are the top five articles published on LCGC International this week.

PEAK Scientific, a provider of laboratory gas generation solutions, has opened a new facility in South Korea.

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.

LIMS are software platforms that provide data management, and were introduced as a solution to sample tracking. However, LIMS quickly evolved into a tool that manages multiple facets of laboratory informatics.

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.

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.
