INTRODUCTION TO STATIC HEADSPACE AND HEADSPACE–TRAP

INTRODUCTION TO HIGH-CAPACITY SORPTIVE EXTRACTION WHAT IS IT? Sorptive extraction is a technique for getting VOCs and SVOCs from a sample into a GC–MS. Uses a focusing step to enhance sensitivity Uses a relatively large volume of polymer sorbent to…

INTRODUCTION TO SPME AND SPME–TRAP WHAT IS IT? Solid-phase microextraction (SPME) is a technique for getting VOCs and SVOCs from a sample into a GC–MS. Uses a thin fiber to adsorb/ absorb compounds Suitable for solids (headspace) and liquids (headspace…

INTRODUCTION TO TUBE-BASED THERMAL DESORPTION WHAT IS IT? Tube-based thermal desorption is a technique for getting VOCs and SVOCs from a sample into a GC–MS. Samples vapours onto a sorbent-packed TD tube Uses a focusing step to enhance sensitivity Complete…
