Analysis of ergosterol for the detection of mold in soils by automated on-fiber derivatization headspace extraction-SPME-GC/MS.

The estimate of ergosterol ([5,7,22-ergostatrien-3beta-ol] has been used by many to relate its concentration to the amount of mold in soils. This new method using on-fiber derivatization-solid phase microextraction-GC/MS method for the analysis of ergosterol presents a quick and straightforward method where low detection limits (1.5 ppb) and good limit of… CONTINUE READING
