A new Thermal Energy Analyzer for direct high-performance liquid chromatographic and gas chromatographic analysis of N-nitrosamides.

The Thermal Energy Analyzer (TEA) has been modified to make it capable of detecting compounds such as N-nitrosamides. This modified TEA(amide) can be used with both gas chromatography (GC) and high-performance liquid chromatography (HPLC). Analysis of underivatized N-nitroso amides by GC-TEA(amide) and HPLC-TEA(amide) are also described.
