Solid Phase Microextraction (SPME) with TDU to perform the Hot Injection and Trapping Technique (HIT)
Automated Solid Phase Microextraction (SPME) into a gas chromatograph with a mass spectrometer detector is shown using the GERSTEL MultiPurpose Sampler (MPS) and Thermal Desorption Unit (TDU). This technique allows for better chromatographic performance when performing SPME analysis and has the unique benefit of allow multiple injections to achieve lower detection limits.
