Hi everyone,

Someone has let me know that, twice now, the CO2 syphon tank in Ryan 2035 has been left open during the overnight bleed/depressurizing process.

Keeping the CO2 tank open overnight is a potential hazard, wastes CO2, and defeats the purpose of depressurizing.

Please remember to close the tank once you begin heating your sample. If you forget, it is also written in the SOP in front of the instrument.

Please let me know if you have any questions.

Best,

Julia
