Crime scene forensic analysis frequently encounters discarded single use (disposable) gloves. Latex gloves, developed in the 1960’s dominated the market and therefore the crime scenes. Each manufacturer has a unique chemical signature, which has been differentiated using FTIR, DSC, and TGA. Nitrile gloves entered the market in the 1990’s and has since taken over commercial prominence. Various glove manufacturers’ nitrile gloves were analyzed using X-ray fluorescence (XRF), differential scanning calorimetry (DSC), thermogravimetry analysis (TGA), pyrolysis mass spectrometry (Py-MS), transmission Fourier Transform Infrared Spectroscopy (FTIR), and Attenuated Total Reflection (ATR) FTIR to differentiate manufacturing source. The analysis would potentially aide crime scene investigations by correlating glove source.
