Detection: quadrupole - and/or ion-trap mass detector, scanning mode and/or MS daughter ion MS detection; DAD: for wavelengths, see A.2.1; Spray gas: nitrogen (bottled/generator); Ionization: API electrospray positive, fragmentor 120 V. 检测器:四极杆和/或离子阱检测器,“扫描模式和/或质谱二级质谱检测器”---可以这么理解吗? Spray gas: 什么意思 是什么气?载气?喷雾气? 离子化: API阳极电喷?电压120V? 没见识过液质 哪位老师帮忙翻译一下
