ESA Biosciences has released a new High Performance Liquid Chromatography (HPLC) detection tool, which uses platinum to help in chromatographic separations.

The apparatus is designed for use in the laboratory, working as part of the technical equipment needed for polymer analysis and manipulation.

Targeted at laboratories which use Tetrahydrofuran (THF) as a "mobile phase component" in chromatographic separations, the new product works using a process known as Charged Aerosol Detection (CAD).

Describing how the system works ESA explained how the HPLC column eluent is nebulised, with the resulting droplets evaporated at ambient temperature producing analyte particles.

A second stream of gas is positively charged as it passes a high-voltage, platinum corona wire.

Then, as ESA details, the "charged gas collides with and transfers charges to the opposing stream of analyte particles".

"A negatively charged, low-voltage ion trap removes high-mobility particles while analyte particles transfer their charges to a collector. The charge transferred to the collector is in direct proportion to analyte mass."

The result is what is termed a "robust HPLC detection technology that delivers advanced capabilities of interest to every HPLC user-lab".

ESA Biosciences has been in operation for almost 40 years and is one of the world's leading manufacturers of scientific and pharmaceutical analytical instruments.
