The most versatile and sensitive headspace sample handling and preconcentration system available.
The all-new 7650HS-CTS recovers a wider range of compounds at lower concentrations than any other headspace system available. The 7650HS-CTS supports sample analysis via large and small volume static headspace (1–1000cc) to accommodate a wide range of concentrations with quantitative recovery of compounds with boiling points from -50°C to >400°C. The 7650HS-CTS maximizes throughput while offering state-of-the-art performance in quantitative accuracy, sensitivity, and low carryover. The 7650HS-CTS resides to the right of the GCMS system, with an advanced preconcentration trapping system on top of the GC to ensure complete sample transfer to the GC column. The 7650HS-CTS is fully 1D/2D GC compatible, supporting the latest food, flavor, aroma, product testing, environmental, and clinical applications. The 7650HS-CTS uses a unique approach for sample enrichment that characterizes headspace concentrations more accurately than any other headspace solution. Using Entech’s OCMTS (On-Column Multi-Trapping System) the headspace first passes through a thick-film GC column to perform an “On-Column Extraction”, allowing far better recovery of heavy and thermally labile compounds than direct trapping onto Tenax® or other more reactive adsorbents. Downstream water management and cold traps recover lighter compounds unretained by the initial thick-film column and after a water bakeout step all traps are backflushed to the GCMS completing the quantitative recovery of the largest range of compounds currently possible. No other technique gives a clearer picture of what is in the sample headspace, covering boiling points of -50°C to >400°C, producing chromatograms that truly represent the amounts that are in the equilibrated headspace rather than the artificial picture created by SPME and other non-equilibrated headspace techniques.
