I want to make a method for determination by GC-MS. There is methods for GC-FID but i want to analysis alcohols with GC-MS
I am trying to analysis Methanol, Ethanol and isopropyl alcohol.
I am using DB-VRX Column.
My solvent is water.
Oven program is 40 °C (5 min)
7 °C increase 100 °C
When i try this method i want to find alcohols. But methanol peak comes so close with solvent peak. I can not seperate them.
Question 1: Is water harmful for column or anything else ?
Question 2: Which solvent can i use except water ?
