i have to analyse my product sample (1M ethanol solution) coming out from Fuel cell. problem is sample should be free from water only then sample can be injected in GC-MS.
how do i remove water from sample?
(water content in the sample is very high, was wondering if HPLC can do dat i am not sure though...do suggest a method for separating water from the sample)

in my case probable compounds that could be present in the sample are ethanol, (acetic acid, acetaldehyde, acetone ) in trace amounts. what column should i use a polar or non-polar ( if so which column in particular fused silica gel will do??)

I hope some one could help me in this.

Hi, u can do your Analysis on RPHPLC using the C18 Column with Methanol:Water as an Mobile phase (UV Detector). u can also do it by GC with non polar column by removing water with some dehydrating agent

Try this if possible

Thank you for you suggestions. i have tried using dehydrating agent but of no help. since the solution is 1M it contains nearly about 95% of water so removing is difficult.

ne way i will try if i can use this RPHPLC.
