On-Site Trace Chemical Detection, Part 2: IMS and DMS Working Together
Last month we discussed how IMS and DMS are used for trace chemical detection. Now we consider how the two technologies can be used in tandem to achieve greater selectivity and sensitivity and fewer false positives.

On-Site Trace Chemical Detection, Part 1: Understanding Ion Mobility and Differential Ion Mobility Spectroscopy
The first installment of this two-part series discusses ion mobility spectroscopy (IMS), the leading contender for fast and reliable detection of trace chemicals, and differential ion mobility spectroscopy (DMS), a related technology that provides faster, smaller and more sensitive sensors capable of detecting chemicals in environments with greater concentrations of interfering substances.
