After heating a blood or urine sample containing each alkyl alcohol and t -butyl alcohol (IS) in a 7-ml vial at 55℃ for 15 min, 5 ml of the headspace vapor was drawn into a gas tight syringe and injected into a GC port. All vapor was introduced into an Rtx-BAC2 middle-bore capillary column in the splitless mode at 0℃ of oven temperature to trap entire analytes, and then the oven temperature was programmed up to 240 ℃ for GC measurements by flame ionization detection. The present conditions gave sharp peaks of each compound and IS, and low background noises for whole blood or urine samples. Isobutyl alcohol and methemoglobin in human whole blood, after inhalation of isobutyl nitrite gas for 2 min, could be actually determined.}, pages = {138--139}, title = {低温オーブントラッピングキャピラリーガスクロマトグラフィーによる生体試料中アルキルナイトライト分解産物の高感度分析}, volume = {20}, year = {2002} }
