Empower3- Agilent HS-GC
Posted: Fri Jul 06, 2018 7:04 am
Good morning,
I am using an HS-GC method, developed on chemestation, to our head-space instrument HS-GC 7697A, connected to Empower 3.
I using 20 ml head space vials with 1 ml of standard solution containing CHCl3 + DMF + 100uL of H2O.
When inject the diluent, 1ml of 1-Methyl-2-pyrrolidinone (without 100uL of H2O), the injections take place without problems, but when inject the standard solutions the instrument goes to error.
The error that gives me the instrument is "vial leak", at the time of the sample extraction.
I suppose that the error derives from the parameters of method setting such as:
vial paramenter or loop parameter.
Can someone give me some suggestions on how to set them?
For example is better set: fill with constant volume, fill at flow to pressure or fill to pressure in the vials parameters?
Thank you,
Gianna
