TF SPME
TF-SPME (thin-film solid-phase microextraction) is a novel sampling approach for ultra-trace-level analysis of VOCs and SVOCs using sorptive extraction. TF-SPME uses a carbon mesh strip impregnated with a sorptive phase with 100× greater volume than a typical SPME fiber.
- Applicable to a wide range of compound classes
- Environmentally friendly and solvent-free
- Split-flow re-collection on compatible instruments enables repeat analysis under different split conditions for analysis over a wide concentration range

Overview
As with traditional SPME, TF-SPME membranes can be used to extract volatile and semi-volatile analytes from solids and liquids using immersive or headspace techniques. However, the much greater surface area offers high extraction rates and sensitivity, making TF-SPME an ideal sampling tool for ultra-trace-level analysis.
Selectivity for certain classes is possible with starter kits for four sorptive phases:
- PDMS is suitable for non-polar VOCs and SVOCs
- PDMS/CAR is suitable for VVOCs
- PDMS/DVB is suitable for general analysis of VOCs and SVOCs
- PDMS/HLB has a balanced affinity for polar and non polar compounds, and is suitable for analysis of ‘unknown’ VOCs and SVOCs
