While I know this is a chromatography forum, I need to ask some fellow chemists about their opinions on Thermal Analysis. My lab is looking to replace an old TGA from TA instruments, and while upgrading to a new one from TA is an option, we want to look at others. Has anyone else ever used Perkin Elmer thermal analysis instruments? (Specifically TGA 4000 and STA 6000). What about other companies?

Thanks,
Tim
