Hi. We recently got a new GC/MS from Agilent and want to transfer a method over from our old GC/MS to the new one. My difficulty is how to accomplish this with a Screening method. We are moving from Agilent MSSCREEN software to the new Deconvoluting Reporting Software (DRS) which requires us to change the entire configuration of the GC/MS - column, oven parameters, etc. It comes with the new software, but can anyone give ANY guidance on validating this new method. I am finding it difficult since I have qualitative standards but no quantitative ( I have vitually no method validation experience- nor does anyone in our lab.) Any guidance of where to turn would be greatly appreciated.
