摘要
研究依托四极杆飞行时间气质联用仪(GC-Q-TOF),证实环己基氨基磺酸钠衍生产物为环己醇亚硝酸酯。结合火焰离子化检测器(FID)检测器的原理,解释了环己醇亚硝酸酯和环己醇的峰面积之和在气相色谱测定过程中稳定的原因。通过对比酸性环境和脱水处理对衍生产物环己醇亚硝酸酯和环己醇峰面积变化,推断出环己醇亚硝酸酯向环己醇转化的反应机制,为气相色谱法(GC)和气相色谱-质谱法(GC-MS)准确测定食品中环己基氨基磺酸钠提供了建议措施和理论依据。
This study confirm that the sodium cyclamate derivative product was cyclohexanol nitrite by gas chromatography-quadruple time of flight mass spectrometry(GC-Q-TOF). Combined with the principle of the flame ionization detector(FID), the reason for the stability of the sum of peak area of the cyclohexanol nitrite and cyclohexanol in the process of gas chromatography was explained. By comparing the peak area of derivatives of cyclohexanol nitrite and cyclohexanol on acid environment and dehydration treatment change, the reaction mechanism of the conversion of cyclohexanol nitrite to cyclohexanol was deduced, which provides proposed measures and theoretical basis for the accurate determination of sodium cyclamate in food by gas chromatography(GC) and chromatography-mass spectrometry(GC-MS).
