Cyanide purity testing is relatively simple with the use of graded immunoassay test strips. ‘Quantofix’ manufacture a cyanide test kit with 100 strips, able to read between 1 - 30 mg/ litre (see above). The cost of the kit is ~ US$100. To establish purity, one dissolves 30mg of potassium cyanide powder into distilled water. A colour change on the test strip will indicate a positive reading.
Using Cyanide for a Peaceful & Reliable Passing
Only a small amount of cyanide is required for a peaceful death (ie. 1-2 gms: a teaspoonful). The sodium or potassium cyanide can be dissolved into half a glass of water. The solution is stable in neutral or alkaline solutions, so do not use carbonated water. The solution should be drunk quickly.
Alternatively, the powder can be packed into ‘OO’ gelatin capsules and then taken with a glass of water. The powder density is 1.5gm/cc and a single ‘00’ capsule will contain
