Increased use of liquid chromatography/mass spectrometry (lc/ms) for structural identification and trace analysis has become apparent. Thermo-spray lc/ms has been used to identify by-products in phenyl isocyanate precolumn derivatization reactions Liquid chromatography/thermospray mass spectrometric characterization of chemical adducts of DNA formed during in vitro reaction lias been proposed as an analytical technique to detect and identify those contaminants in aqueous environmental samples which have a propensity to be genotoxic, t.e.. to covalently bond to DNA.

Stage that requires high efficiency as well as speed, due to the complexity of the sample matrix, and hence it is particularly challenging to achieve the goals. Therefore, the development of a rapid, sensitive, and reproducible method has been required for separation and determination of capsaicinoid compounds. The addition of ultraperformance liquid chromatography-mass spectrometry (UPLC-MS) method fulfilled these aforementioned demands and showed some complementary advantages to the conventional HPLC-MS, u-HPLC methods in terms of shorter analysis times, low sample volume, and much improved sensitivity [71]. Therefore, nowadays this UPLC-MS technique is routinely performed in pharmaceutical industries and related contract research institutes, laboratories concerned with biochemistry, biotechnology, environmental analysis, natural product research, and several other research fields. The UPLC-MS method has successfully been applied for the determination of n-DHC, C, DHC, h-C, and h-DHC present in the varieties of hot peppers [71]. [Pg.97]

Urine analysis for illegal drugs is increasingly performed in forensic laboratories (especially in Japan). Gas chromatography-mass spectrometry (GC-MS) is extensively used because of its versatility and reliability. By way of sample preparation for GC analysis, conventional liquid-liquid extraction has a widespread use, but it is not only laborious but also environmentally unfriendly due to the consumption of considerable amounts of organic solvents. Therefore, microintegration of the sample preparation procedure is required. [Pg.13]

Preliminary results from gas chromatography/mass spectrometry and high-performance liquid chromatography analysis of a solid intermediate recovered from the tetrytol testing identified several energetic compounds, including trinitrobenzoic acid (TNBA) and trinitrobenzene (TNB) (Winkler, 2001). Also, picric acid (PA) was identified in the solid intermediate (personal communication between John Coffey, senior environmental chemist, CH2M Hill, Inc., and Darren Dalton, PMACWA, February 21,2001).
