WebGC/MS analysis of TATP is hindered by stationary phase activation in very short periods of time. Due to the lower temperatures used in LC, this problem is not encountered. This study presents a method that is suitable for the detection of TATP at levels as low as 100 pg μl −1 (10 ng per 100 μl). WebDec 3, 2024 · The small amount of TATP used in the experiment was synthesized according to a method described in the previous literature . The purity of the TATP sample was analyzed using gas chromatography mass spectrometry (GC-MS) (Figure S1). The results showed that there was only a little residual acetone in the TATP sample.
WebTATP in post explosion exhibits was reported earlier to be best recovered from vapor phase. A typical procedure includes its adsorption on Amberlite XAD-7, elution with acetonitrile and analysis by GC/MS. In this work, improved recovery of TATP from the vapor phase was achieved by SPME using PDMS/DV …
