Der HT3 vereint traditionelle statische mit dynamischer Headspace-Probenvorbereitung mit einem Probengeber mit 60 Positionen. Temperaturen von bis zu 300°C können im gesamten Probenweg konstant gehalten werden.
HT3 Static and Dynamic Headspace Vial Sampler
The HT3 incorporates traditional static headspace with the option to perform dynamic headspace.
In the Dynamic mode, upon completion of heating and mixing, the headspace is continuously swept with an inert sample gas that is routed through a sorbent trap thus removing more of the analyte and concentrating it on the trap. The trap is then heated and back-flushed to the GC column for separation and detection.
Static Headspace analysis is a time-tested and robust technique for the analysis of volatile compounds in almost any matrix. The popularity of the technique is due to Headspace analysis providing a clean, reliable result.
Teledyne Tekmar draws on our experience as a leader in low-level VOC analysis with the introduction of a next generation Headspace instrument, the HT3™ Static and Dynamic Headspace System.
Dramatic improvements in sensitivity are achieved with the new Dynamic Headspace option, while maintaining the ruggedness and reliability of a traditional Static Headspace instrument.

Autosampler - The HT3 comes with a standard integrated, 60-position autosampler, providing true walk away automation. Vials are automatically queued into the platen heater ensuring reproducible dwell times. Vials may also be added during a run to increase productivity. (Optional 9 or 12mL vial inserts sold separately.)
Valve/Loop System - The HT3’s valve and loop sample method has proven to be the industry’s most reliable technique for headspace sampling. The entire sample path is Siltek™ and can be heated up to 300oC thus minimizing analyte carryover. Different loop sizes ranging from 100μL to 5mL may be used depending on application.
Removable Sample Path - Easy access to sample path allows for trouble-free removal, maintenance and safety.
Platen Heater - The platen heater offers a 10-position, highly regulated heating chamber. Temperatures are controlled up to 300oC in increments of 1oC. A strict control of the platen heater chamber allows for superior reproducibility in sample preparation achieving greater sample accuracy.
Electronic Mass Flow Controller (MFC) - The patented MFC has the ability to control pressure and flow to assure consistent volume control regardless of external conditions for all samples.
Two-Stage Needle - This unique design allows for the continuous sweeping so critical to dynamic headspace analysis.
Trap - Sorbent traps allow for dynamic compound concentration and are available in a variety of sorbent packing materials. Some typical sorbents are listed below:
• Tenax - General purpose trapping agent
• Silica Gel - Choice for polar compounds
• Carbopacks™ - Variety of types for extended range compound trapping capabilities
• Carbo Sieve III - Extremely strong sorbent for extremely volatile compounds
Dynamic Option – This dynamic headspace sampling option concentrates the headspace sample and thereby increases your sensitivity requirements compared to that of the conventional static mode. Dynamic headspace allows for flexibility by allowing the user to set up a schedule utilizing both static and dynamic modes interchangeably.
Variable Fill Pressure Control – (patent pending) Utilization of a Mass Flow Controller, which reads and controls both pressure and flow in order to meet user-defined requirements for pressurization loop filling and static pressure assuring sample volumes are consistent from one sample injection to another.
