Low molecular weight aldehydes have been quantitatively measured in distilled water at levels similar to their published threshold odour concentrations by a simple and sensitive purge and trap method. Isobutyraldehyde, isovaleraldehyde and 2-methyl-butyraldehyde were isolated from aqueous samples by purge and trap onto Tenax-TAm adsorbent. The aldehydes were thermally desorbed onto the head of a cryogenically cooled gas chromatography column and eluted by temperature programmed gas chromatography. The method has a linear range of 0.5 μg-1 to 100 μgL-1 with an average precision of 10.9% relative standard deviation for the aldehydes studied. |
