Empty sorbent tubes

Empty - stainless steel tubes

C0-AXXX-0000

Empty industry-standard thermal desorption tubes are available in stainless steel, inert-coated stainless steel and glass. They are typically used as carrier tubes: stainless steel and inert-coated tubes are primarily used to hold HiSorb probes or radial sorbent cartridges in a thermal desorption instrument, and glass tubes are primarily used for direct desorption.

  • Suitable for use with any industry-standard thermal desorption instrument
  • Unique ID number in clear numerical and barcode format
  • Sampling arrow to indicate the direction of flow though the tube
  • Inert-coated tubes are coated inside and out with industry-leading SilcoNert™
  • Glass tubes use a restriction as opposed to a frit to allow for better recovery of reactive and high-boiling species

Overview

Empty stainless steel and inert-coated tubes come fitted with a primary gauze (also referred to as a sorbent-retaining gauze), located 15 mm from the sampling end of the tube. The gauze ensures the HiSorb probe or radial sorbent cartridge is retained in the tube. If the tube is used for direct desorption, the gauze prevents material passing into the flow path of the instrument.

Empty glass tubes have one of three types of restriction: standard, central (direct desorption) and unrestricted, and are primarily used for direct desorption. This is because the analyst can see the material in the tube and ensure it is positioned correctly (or hasn’t become damaged).

  • For large samples, tubes with a standard restriction (C0-BXXX-0000) are recommended.
  • For small samples, tubes with a central restriction to ensure the sample is held centrally in the tube (C0-NXXX-0000) are recommended.
  • For materials that are difficult to pack into a sorbent tube, unrestricted tubes (C0-FXXX-000) are recommended. Note: A torsion spring and glass wool are required at both ends of unrestricted tubes to prevent material flushing into the flow path of the instrument.

Stainless steel and inert-coated tubes can be used in conjunction with PTFE liners for direct desorption of semi-solid materials or those that are otherwise difficult to handle. The PTFE liner is disposed of after sampling, leaving the tube free of residue and ready for conditioning prior to re-use.

Self-packing

For advanced users with expertise in sorbent packing and the appropriate equipment, purchasing empty tubes is a viable option.
