Qualitative screening of hazardous waste drum mixtures

Two Fourier-transform infrared (FT-IR) spectrometry techniques were used to identify major components of 11 hazardous waste samples previously analysed by gas chromatography-mass spectrometry. Method 1 was forward searching of the unknown spectrum against a library of known spectra. Method 2 used an...

Zusammenfassung:	Two Fourier-transform infrared (FT-IR) spectrometry techniques were used to identify major components of 11 hazardous waste samples previously analysed by gas chromatography-mass spectrometry. Method 1 was forward searching of the unknown spectrum against a library of known spectra. Method 2 used an automated rule-based program, PAWMI (Program for Automated Waste Mixture Interpretation). Forward searching was useful when unknowns were relatively pure compounds or commercial mixtures. It could be used to identify non-chromatographable components of mixtures. PAWMI was successful in identifying components with concentrations greater than 1 per cent. There are 35 references.
