when spinnin down the dcm using a rotary vane pump, I felt spaced out for a couple mins. could’ve just been the solvent vapors, but wasn’t placebo "Nothing is true, everything is permitted." ~ hassan i sabbah

but wasn’t placebo Rotary vane pump? Were you pumping the rotovap? Too much vacuum, I think. If you did not have a cold trap between the pump and the system some DCM was unable to liquefy in the condenser and was pumped into your lab environment. I saw that happening even with a 2-stage diaphragm pump at vacuum around 300 mbar or less. There is a definite smell of DCM in the air. Usually I remove most of DCM at 500 mbar and 35-37C. The higher the temp and the pressure, the better, because the water feeding the rotovap condenser is around 12C these days and I need the temp difference to be as high as possible for the condenser to work efficiently. When the DCM stops dripping from the rotovap condenser I gradually lower the pressure to ~10-15 mbar (my diaphragm pump would not go lower than that and I am too lazy to switch to a rotary vane). P.S. Sorry for telling some obvious things to real chemists, but it could be of some help to aspiring ones. Do not seek the truth, just drop your opinions.

yeah, I would partially close the vac reg. valve, open the coldfinger condenser valve, evacuate for a few secs, then close the condenser valve. "Nothing is true, everything is permitted." ~ hassan i sabbah

the Cerilliant standard above shows a parent ion peak at 189.125 m/z (the mass specs at work are triple-quads, much higher resolution). this is my sample, and my spectra. benzyme attached the following image(s): IMG_5907.jpg (1,763kb) downloaded 362 time(s).

Hmmm, black holes and lots of pretty 5-meo on the same page! Coincidence? I think not!!! -the 5 is there, you are not. Sine experientia nihil sufficienter sciri potest -Roger Bacon
