In another thread, I had asked TSORon about these and what liquid explosives they are designed to detect but he stated he could not divulge any info on them. The container for these that I saw was unmarked. If I look up any other equipment that TSA uses, there is plenty of open source info on these. However, to date, I have not found any open source info on the non-dipping test strips.
