The polar metabolites of polycyclic aromatic compounds (PACs) are of significant oncological interest. In contrast to parent PACs, isomer selective detection of polar PACs by laser excited Shpol'skii spectrometry (LESS) is severely limited by excessively broadened spectra and rapid photodegradation in n-alkane solvents. To minimize these limitations a 10-min derivatization procedure was developed to produce corresponding methoxy compounds, that exhibit the Shpol'skii effect. By use of the extraction and permethylation procedure, the selective detection of a mixture of hydroxy-benz[a]anthracene isomers spiked at the low picogram level into urine and blood matrices was achieved. A detection limit for 1-hydroxybenz[a]anthracene was 0.6 part per trillion, or 12 fg (0.05 fmol) on a 20-microL sample.

“…It is for this reason that many detection schemes are being borrowed from GC and adapted to SFC. Some examples of this include SFC/MS (6,7), SFC/FTIR (8), and SFC/FID (9)(10)(11), as well as thermionic (12), dual flame photometric (13), and ion mobility (14).…”

“…Then, the temperature should be carefully controlled for quantitative analysis, but it is practically difficult. An alternative approach for quantitative analysis might be the use of a deuteriated compound as a standard (14). But, it is also impractical, since it takes a long time for synthesis of such compounds.…”

Supersonic Jet spectrometry Is combined with synchronous scan luminescence spectrometry; the fluorescence wavelength Is synchronously scanned with the excitation wavelength. When the wavelength difference Is adjusted to 0 nm, a single component gives a single peak In most cases, like chromatography. The resolving power, the ratio of the dynamic range and the line width, is 2.5 X 10\ which corresponds to chromatography having a theoretical plate of 1010.

“…In this work we evaluate the analytical potential of cellulose substrates by the fluorescence line-narrowing (FLN) technique. Fluorescence line-narrowing, often referred to as optical site-selection or energy-selection technique, has been demonstrated and used for a variety of sample media, including frozen alkane solvents (4)(5)(6)(7)(8), alkane single crystals (9), matrix isolation media (10), organic glasses (11)(12)(13), and most recently, in thin-layer chromatographic plates (14). Previous analytical applications of the FLN technique for the analysis of a coal liquid sample (15), metabolites, and DNA adducts of polycyclic aromatic compounds (16,17) have been conducted with frozen organic glasses.…”
