各位晚上好
請問欲分析植物萃取物的成分用什麼儀器比較好?
因為我的指導老師和小弟並非化學背景,所以對儀器分析方面很不懂
小弟先前是使用40%乙醇水溶液萃取植物
得到該植物萃取液後送去SGS分析
其分析的儀器是GC-MS
這幾天SGS傳回結果給小弟了
可是分析的組成不是小弟想要的活性成分
跟文獻落差很大
小弟推測植物萃取物的成分沸點太高,不易揮發
所以GC-MS分析出的成分都是不易揮發的物質
文獻是先經由HPLC純化後,再送入LC-MS分析
請問有獨立的LC-MS嗎?
小弟想直接把沒有純化過把萃取液打進去
因為想知道整體植物的活性成分組成
請問這樣可行嗎QQ?
還是有其他方法能分析組成請前輩告知一下無知的小弟,謝謝
