Product Details
- Focusing traps, known as TD cold traps, are constructed of quartz and packed with a sorbent bed up to 60 mm. Traps can contain multiple sorbents for use with an extended range of analytes.
- Long-term (brass) storage caps ship as standard with Agilents preconditioned sorbent tubes. Ferrules should be replaced routinely or when switching applications.
- Short-term or DiffLok caps are convenient for in-lab use. For transport or storage longer than three days, long-term storage caps should be used.
- Markes CapLok is a two-part tool specifically designed to simplify the capping and uncapping of sorbent tubes without overtightening.
- Gold-plated flexible metal ferrules are recommended for use with Agilents Ultimate Union and other Capillary Flow Technology (CFT) products.

New Agilent UltiMetal Thermal Desorption Tubes for GC, GC/MS
Agilent has expanded its thermal desorption offering with the new UltiMetal Thermal Desorption (TD) Tube portfolio, extending the Agilent Inert Flow Path from sample collection through detection. The tubes feature Agilent’s proprietary UltiMetal surface treatment, which reduces analyte interaction with active metal sites for more consistent recovery and improved reproducibility. Available in single- and multi-sorbent configurations in industry standard dimensions, the portfolio is compatible with leading TD platforms and supports air toxics, materials emissions, and PFAS workflows.
