Headspace Sorbent Pens™
The Sorbent Pen™ uses an entirely new approach for sample extraction. Direct insertion of the Sorbent Pen™ with its internal adsorbent into the vial headspace allows a new technique called “Vacuum Assisted Sorbent Extraction”, or VASE, to recover a far wider range of compounds than ever before. With Sorbent Pens™, both VOCs and SVOCs can be measured in wastewater, breath condensate, alcoholic beverages, and virtually all other matrices. VASE offers a tremendous advantage over other extraction techniques that perform extractions at atmospheric pressure where diffusion rates are suppressed. Sorbent Pens™ perform sample enrichment offline from a GCMS, allowing all samples to extract simultaneously and for longer periods of time. This approach results in high throughput while yielding a more complete and reproducible extraction for more sensitive and quantitative measurements. The low cost 5800 Sorbent Pen™ Desorption Unit (5800 SPDU) makes this exciting new technique both affordable and practical for virtually any laboratory’s budget. Then move up to 90 sample automation with the 7800 Autosampler for the ultimate in laboratory productivity. Join the Sorbent Pen™ movement and take advantage of the next generation in GCMS sample preparation.
