Conclusions:
The vapour pressure of tetraammineplatinum(II) hydrogen carbonate was determined to be approximately 1 x 10^-6 hPa at 25 deg C.
Executive summary:

In a guideline study, conducted to GLP, the vapour pressure of tetraammineplatinum(II) hydrogen carbonate was determined by the vapour balance method to be approximately 1 x 10-6 hPa (1 x 10-4 Pa) at 25 deg C.
