...rts per trillion (ppt) levels achievable with suitable analyte enrichment provided by a pre-concentrator. Once the MS fingerprint of an unknown substance is measured, it can be compared online with a database of known substances enabling real-time rapid identification. In 2014 pre-prototype instrument was demonstrated in FP7 Project SNIFFLES. ChemSniff will develop a more compact MS-based than exi ...

...y and with a stand-off capability – critically it is able to detect trace levels below parts per million. Once the MS fingerprint of a unknown substance is measured it can be compared online with a database of known substances enabling real-time rapid identification. Sniffles will develop a LIT MS based device with a larger mass range than other comparable MS techniques. Methods for miniaturisatio ...
