Hi Elliott,
I have submitted a request to get Orbitrap Exploris GC 240 MS added to the standard list of instruments maintained by the HUPO Proteomics Standards Initiative (PSI). This could take a few days. In the meantime, you can submit your data with a different Orbitrap Exploris model selected in the instrument field. I will change it to Orbitrap Exploris GC 240 as soon as it is added to the list.
Please let me know if you have any questions.
Best regards,
Vagisha
