Analysis of cave atmospheres by comprehensive two-dimensional gas chromatography (GCGC) with flame ionization detection (FID)

---

a b s t r a c t:
In this paper, we describe a simple method for sampling, pre-concentrating, and separating volatile and semi-volatile components from two different cave atmospheres. Sampling is performed by capturing a volume of cave atmosphere in a Tedlar bag or Suma canister for sample storage and transport back to the laboratory. Loading a portion of the sample on a multi-bed sorption trap allows for sample preconcentration prior to separation and detection of components on a comprehensive two-dimensional gas chromatograph (GCGC).Comparison of two Texas caves reveals the power of comprehensive
two-dimensional gas chromatography (GCGC) for volatile separation and detection, and to our knowledge marks the first use of GCGC for the analysis of cave atmospheres. Analysis of the results revealed 138 and 146 chromatographic signals over an S/N threshold of 500 and direct comparison of
the two samples revealed 50 identical chromatographic signals. This study is a first step toward demonstrating the ability of GCGC to separate the complex volatiles and semi-volatiles in the cave atmosphere as a fingerprinting tool
