Orbitrap any day and above ToFs and triple quads in my experience!

Never been so satisfied with a GC-MS system before! : )

Thanks,

Hello,

thank you for your suggestion. Unfortunately, we have to choose from the triple quad models mentioned above.

With best regards,

I am pretty sure that WU has the Agilent model. I don't use it myself as we find problems making the complexes 'fly' well. But it has been working for many years. Sorry I can't be more helpful, they are all good systems, it'll come down to price.

Thank you again for your answers and suggestions. One of the hard limits is our budget, which has been set. The companies that are being considered are those that came forward with their offer after our intention to purchase the instrumentation and the budget have been announced. Therefore, I assume Sciex and Waters are absent as they might not be able fit within the budget we have.

Buy agilent, for sure it is the best.
