Markes - Model C-TF-PDVB-KIT -Thin Film SPME Starter Kit

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
• Robust fiber design for sampling in challenging environments
• 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
• Starter kits with a range of phases offer a cost-effective introduction

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
