This method involves accurately weighing out a small sample of powder (~200mg +/- 0.5mg), drying it in an oven at 1000
C
to determine the presence of any significant amount of water, then dissolving it in distilled water and, finally, titrating with 0.1N hydrochloric acid. Methyl Orange is used as an indicator to determine the point at which the pH rapidly decreases.
A detailed step-by-step account of this process has been provided to Exit by ‘htveld’ and is available on the ‘Prime Posts’ section of the Exit Forums. See: http://bit.ly/29LeP6a
Exit is also grateful for the work of ‘chriskay’ & ‘ billleboeuf’ in the Exit Forums <http://peacefulpillforums.com/ > for their suggested refinement to the quantitative testing proceedures described in this chapter.
Testing Nembutal - Summary
• Qualitative testing is simple screening test carried out using the Spot Test barbiturate strips. This provides no information on sample purity.
• Quantitative testing shows a samples purity. • The gold standard test is laboratory testing using gas chromatography (GC). Energy Control laboratory in Spain offers this service
• Home quantitative testing can be carried out using the Exit Bromson Test kit, but results are much less accurate.
• There are three tests that the kit enables - the mot useful are the acid conversion and melting point tests (ACT & MPT).
• The full potential of the new SCiO infrared scanner in providing qualitative and quantitative information on a Nembutal sample is still being assessed.
