Our Lab is going to get a new GC-MS/MS system for analysing multi-class multi-residues in different commodities. Does anyone has hand-on experience using Varian 320 GC-MS/MS or TSQ Quantum GC in doing residue testing? In terms of sensitivity they are quite comparable (not the paper specification). How about their robustness, repeatability, flexiblity in changing from GC to LC-MS/MS mode, etc?

Not too confuse you, but, have you considered the Agilent GC/MS/MS. I have seen a few presentations and they seem to be quite exceptional...can't tell you how good they are since I am looking into them also.
