i am using MassHunter for LC-QQQ. Not sure if this question is version dependent but we are using the latest (9 or 10 I think). In the software you can set the depth of the needle in the auto sampler vial when making an injection. The default is 0 which sets the depth at the default position. You can adjust this by setting a negative or positive value instead of 0. My question is. Do I set the value as negative or positive to lower the depth of the needle in the vial? I am sure that there must be something in a manual somewhere but can’t find anything?
Any help would be appreciated
thanks in advance
