Accurate and repeatable gas flow measurement. Accurate and repeatable gas flow measurement is fundamental to obtaining good results from your thermal desorption-gas chromatograph. The traditional bubble flowmeter, relying as it does on the reaction time of the operator, is a potential source of error.The digital flowmeter eliminates this source of error and makes gas flow easement easier and more accurate. The flowmeter allow…

Viva columns are based on a wide pore material we designed for optimal large-molecule separations.In developing Viva silica, we found that although many commercial wide-pore silicas meet the standard 300 Å mean pore size, most have very broad distributions about this mean, with a significant portion of their pore volume falling below 150 Å.This means a large portion of the surface area is unavailable to larger molecules. Viva…
