For example, a good purity result on the ACT (ie. better than 70%), with a MPT of 1300
C would give confidence that
ingestion of 10gm of this sample will bring about a peaceful death. The test that is most likely to give spurious results (false negative or positive) is the DPT as there are external factors that cannot be totally controlled, eg. the age and quality of the test cassettes.
If, however, a sample fails all three tests, it would be wise to source an alternative sample, or seek a laboratory assay.
Additional Home Quantitative Tests Water Content Test (WCT)
The presence of water in any significant amount in a sample of Nembutal powder is an adverse finding. Nembutal powder will readily absorb water from the air. This is why it should always be kept tightly sealed in an air-tight container.
To determine water content in Nembutal powder, accurately weigh out and record ~1 gm of the powder and place it in a laboratory oven with the temperature controlled at 1000
30 minutes in the oven, let the powder cool in a desiccator and re-weigh to establish the percentage of water content. The percentage should be < 5%
Acid Titration Testing (ATT)
Reliable testing to quantify the presence of adulterants or degradation requires sophisticated equipment. A useful titration test can be carried out at home, but careful attention to detail is essential to ensure an accurate result.
