Seized Drug Analysis Using FTIR with Mixture Searching 
FTIR spectroscopy is a SWGDRUG Category A technique for illicit drug identification. However, it is underutilized in many forensic laboratories. This is largely due to the ambiguous results it can provide when analyzing seized drugs that are mixtures. These results are difficult for the forensic scientist to confidently support when giving expert testimony.

Most labs rely heavily on GC/MS and are confident in the results it provides. This presentation discusses the use of new FTIR mixture searching software and simple ATR sample analysis for rapid screening of seized drugs with a focus on using infrared mixture search data to confidently support GC/MS results for more effective expert testimony.

Real-Time, Continuous Hazardous Air Pollutant (HAP) Detection by GC-MS alternative
US EPA methods for measuring hazardous air pollutants (HAPs) in ambient air include TO-14a and TO-15. Traditionally for these methods, samples have been collected in specially prepared “Summa type” canisters and transported to a laboratory for analysis by gas chromatography mass spectrometry (GC-MS). GC-MS allows for speciation and quantification of many HAPs and non-HAPs within the sample at ppm to ppb levels, but in many cases, the customer must wait weeks for a result. Novel technologies have been recently developed that allow for 10s - 100s of compounds to be monitored simultaneously in real-time by FTIR gas analysis. Similar detection limits as those required in TO-14a/TO-15 can be achieved within 1 minute with minimal concern for sample integrity. This presentation will discuss both the hardware and software advances that now allow for ambient air monitoring of HAPs in real-time by FTIR.
