求帮忙分析下刚做的固相微萃取-气质?本人刚接触固相微萃取- 气质联用 ,一点都不懂啊。下面是我固相微萃取(50/30μm DVB/CAR/PDMS fiber)一种 洋葱 挥发性成分后的气质图,出来我要的物质峰有点少(别人有十几种),前面是不是重叠了,且后面几乎没峰了(?)。参考文献程序升温: 35 ℃ for 2 min, raised to120 ℃ at 5 ℃/min and held for 5 min, increased to 150 ℃ at 3 ℃ /min and held for another 2 min, and finally raised to 220 ℃ at 10℃ /min and held for 5 min.不分流。是不是程序升温有问题,还是什么,求高手分析帮忙!QQ截图20141009222415.pngQQ截图20141009222611.png查看更多3个回答 . 16人已关注
