Luminescence Spectrometry

Four polycyclic aromatic hydrocarbons are identified in broiled hamburger at the part per billion level by low-temperature molecular luminescence spectrometry (LT-MLS). Hamburger extracts in a Shpol'skii solvent are injected onto a moving sample cooling device maintained at 15 K in a vacuum. Results obtained by the present system are compared with those obtained by constant energy synchronous luminescence spectrometry (CESLS) at 77 K and by high-performance liquid chromatography (HPLC) with multiwavelength detection.
