Photothermal interferometry is an ultra-sensitive spectroscopic means for trace chemical detection in gas- and liquid-phase materials. Previous photothermal interferometry systems used free-space ...

Alkanolamines are polyfunctional molecules that include the properties of both alcohols and amines, and because of this they serve as key intermediates in the development of a wide range of products.

The microseepage of gaseous hydrocarbons often creates a soil atmosphere containing lighter hydrocarbons (C1-C5). The gases in the soil may be sampled and analyzed to determine the specific mix of ...
