hum-- well first of all, know the difference in how a desktop vs a hand held is used operationally by TSA. Swabb ( contact ) vs IMSC Vortex collection in a handheld or conveyor configuration present two different uses, operationally speaking.
Think DOGS = IMSC Hand Held...if TSA had a reliable hand held that met certain specs, it would mix that in with dogs and create a flexible ETD layer that roams and can be concentrated. Further, TSA is indicating need as they paid IMSC some $2M to develop non-contact.
In terms of your statement: no one is buying. Not true, the purchase process by gov. is long and very difficult to see. To date, besides govs and gov. regulated "shippers", the rest of the market has not really been born. Every now and then a State Police unit will request info on one but their buying is sparodic, minimal and negligable. All of DHS will be buying thru TSA's purchase vehicle ( coast guard, SS, border, transit etc). So until the protest is removed, there is no buying.
Fear not, the loneliest/homeliest DOS/CMOs are at S-M-- they have nothing new approved or nothing approved that does NOT contain nuclear material. Bolduc/McGann/Jones ran circles around them.
