Gc Ms liner cleaning

[batuhanqqqq]

Hello friends,

I use a lot of gc ms liner in the laboratory. I want to fill these liners and use them again to reduce the cost, but it is not always possible to fill the glass wool cotton in the same way. Is there any procedure to clean them or is there a company where I can fill these liners?

There is a number of such services:

Hi,
for analysis of mineral oil in GC-FID I tried to clean liners in this manner and I obtained a good result:
- wash with strong acid eg Nitric acid 2M
- wash with deionized water
- wash with methanol or similar solvent to remove water
- muffle at 450°C for some minutes.

I would like to try also deactivation with dichloromethylsilane 5% in toluene but I do not know If it will improve liner performance or not.
