We present pen-probe analyzers based on ion-mobility spectrometrymass spectrometry for in-situ detection of volatile organic compounds (VOCs)mapping of VOCs emanating from surfaces. User approaches probe to the analyzed object,presses a button on the probe. The collected data are uploaded to the Internet cloud for retrievalprocessing. Every data file contains the exact timegeographical co-ordinates of sample collection site. In another embodiment, the pen-shaped probe has been robotized to enable open-space samplingmapping of VOCs emanating from solid specimens.

Our portable mass spectrometer is the first miniature high resolution high mass range mass spectrometer in the world, breaking through the bottle neck of conventional instruments to offer competitive performance to the commercial counterparts,performs even better in high mass range. This instrument has been successfully applied to microbial identificationhelped with samples which are difficult to detect in conventional instruments, exhibiting the advantage of precision analysis.

Through combining the cutting-edge technology of TD-ESI/MS to its comprehensive database library of toxicants, a fast-track toxicant analytical platforma set of standard operating procedures are developed that enables the emergency physicians to access correct toxicological information within a short turnaround timerescue the poisoned patients based on accurate laboratory data.
