ABSTRACT:
A method of and apparatus for analyzing for low concentrations of organic material in the atmosphere without the removal of water wherein an air sample is collected and cooled to form a condensate consisting essentially of water and organic material. The condensate is analyzed by Raman spectroscopy to detect and quantify the organic material.
