DNPH cartridge/LC-MS 방법에 의한 카르보닐화합물 분석에 관한 연구 = Analysis of Carbonyl Compounds using DNPH Cartridge with LC-MS

다국어 초록 (Multilingual Abstract)

Several carbonyl compounds are important because of their irritant and toxic properties, mutagenicity andcarcinogenicity. Therefore, they are regulated in korean odor emission standard.In this study, atmospheric pressure ionization-mass spectrometry (API-MS) is used for the analysis of carbonylcompounds after derivatization with 2, 4-dinitrophenylhydrazine (DNPH) and liquid chromatographic separation.-H]- pseudomolecular ions are most abundant for the carbonyls. Analyticalparameters such as linearity, repeatability and minimum detection limit were evaluated. The linearities (r2) for carbonyls were 0.9977~ 0.9999 when analyte concentration ranges from 25 to 250g/L(n= ~ 3.51% for concentration of 100g/L(n= 5). The minimum detection limit (MDL) was 1.88g/L (0.27 ppb) for i-valeraldehyde. It was shown that LC-MS method has a great potential for carbonyl compounds analysis.
