Manual spiking of thermal desorption tubes is time consuming and repetitive. Automated tube spiking can offer many benefits including improvement in precision and accuracy as well as time savings and fewer health and safety concerns for analysts. The GERSTEL TSS was used to spike replicate tubes at low (25 ng) and high (200 ng) concentrations of a selection of Volatile Organic Compounds (VOCs). Tubes were subsequently thermally desorbed using the TD3.5+ directly into the GC-MS with Selected Ion monitoring (SIM) acquisition. Good Linearity (R2> 0.995) and precision (RSDs ≤5%, n=9) were obtained for all the 12 analytes, demonstrating the benefits of automation to provide quality data.
