Two of the most powerful GC introduction techniques, headspace (HS) and thermal desorption (TD), brought together in a new system

Designed to integrate with either the 70-position G1888 HS system or the 44-position G1290 (7694) HS system from Agilent Technologies, Markes HS-TD system opens up new possibilities to users who require enhanced sensitivity for HS applications and/or require a versatile sample introduction system capable of dealing with any matrix; soil, water or air; solid, liquid or gas.
The HS-TD incorporates Markes UNITY thermal desorber, with its market leading trapping technology and pioneering quantitative sample re-collection facility. UNITY is fully compliant with all standard TD methods. The combined system offers three modes of operation:
- Automated HS-trap – offering enhanced sensitivity and a wider volatility range over conventional headspace and without the foaming and complexity of purge-and-trap
- Method-compliant analytical thermal desorption
- Conventional automated equilibrium headspace
