7820A vs 7890B

[Arne]

Good afternoon all,

what is the word on the street on the quality and usability of the 7820A GC from Agilent.

When would you opt for a 7820A over the option of getting the 7890B?

I know that I do not need sample prep or headspace.

Thank you for the advice!

Hello Goodnight

currently agilent sells only the 7890 GC, which is more modern than the 7820. At the software level and ease of use are similar.

however the model 7890 tends to be faster to lower the temperature
