I'm looking for some starting-out information on detection of peroxide based explosives (like the ones brutally used previously against civilians). everything on the internet is too basic and everything on Web Of Science is too far from applications. specific questions you may have answers to:
1. what are the forms of these explosives? i wouldn't think they're hydrogen peroxides, so what are they?
2. how is detection possible spectroscopically/instrumentation-wise? i'm not talking like a catalase assay, i think that would be horribly inefficient in an airport line. spectroscopists? why wouldn't GC-MS work? I don't think a peroxide would do very well in either one of these (probably destroy the GC column and get obliterated in the MS), but do you know why/can you give me a link to a paper?
3. all explosions are radical reactions... is this true or false. one of my classmates told me this, but i don't see how it could be true.
please, no conspiracy theories, i'm just interested in the science behind these things.
Take a look at GE manufacturer explosive detection devices like vaportracer and itemizer. I can send you shematics on detection process if it helps.

Hi everybody! Some bits and pieces, not very useful:
Peroxides are more general than hydrogen peroxide.
Have a look at the Handbook of Chemistry and Physics, at Safety section
is your basic target.
Hydrogen peroxide is not just an oxygen supplier. The molecule itself is unstable, meaning that the decomposition in water and oxygen provides heat. Over 70% peroxide among water, this heat is enough to vaporize the liquid, hence boom - no fuel needed
. However, it makes a bad rocket fuel: Very limited specific impulse, but very dangerous.
Detecting them: Do they all have some vapour pressure? Or at least, the ones used in explosives? Maybe you could adapt a method that detects ozone in minute quantity: Mix a di-ene with the air, observe faint light emission at room temperature.
Remember that packaging can make explosives undetectable by smell nor spectrum.

I have found over the internet the ATSC LTD website. Which is an explosives detector.
What do you think about that?
