We have been following IMX for some time here (#msg-2017907, #msg-2600884) I think you should know that they are not using a "gas chromatograph" but a an "ion mobility spectrometer". The laser is used to ionize the target analytes, prior techniques used mostly a radioactive ionizer (There are at least 5 other suppliers of explosive detection systems, many using IMS, though not laser ionized). A number of companies are working on similar systems, and while IMX had demonstrated nice results, they lack the finances to get this thing to market, that is the main problem. Last year we did quite well with INVN and the year before with MAGS in this "space". However, INVN is being acquired by GE, and INVN has a "possible" joint venture with IMX to help them launch their Laser IMS bomb detector. With the GE acquisition, it is very likely that the GE based IMS (they have their own technology, though, a little "bulkier" than IMX) system will become standard in INVN' future offerings, closing in essence IMX's "entry port" to the market place (I mentioned that at the time when INVN acquisition was announced). The main problem with IMX is availability of cash, if they get acquired or if they do a secondary here between $13 and $15, fine, if not, they simply do not have the cash to execute a plan that justifies their current market cap of $100 MM. The recent run up is simply a result of the recent publicity and because it is so thinly traded, once the hoopla from their "roadshow" dissipates, they could easily come back to the $10/$11 range. All IMTO, of course. Just like NVEC, the hype may continue and levitate this company.
