CIS Glass Liners from Gerstel

The GERSTEL CIS is a temperature programmable PTV-type GC inlet. The CIS offers septumless, cold injection of volumes of up to 1000 µl for liquid samples. The integrated split function enables the CIS to handle ultra-trace concentrations as well as undiluted samples. Programmed linear heating ensures quantitative, discrimination free transfer of sample components to the GC column for best possible GC analysis results.

The CIS is a general purpose, universal GC inlet. When working with Thermal Desorption or Headspace techniques, the CIS is used for enrichment, focusing and quantitative transfer of analytes to the capillary column.

The dimensions of the glass liners (unless otherwise specified) are:

CIS 3 - OD 2 mm (ID 1.5 mm); length 93 mm
CIS 4/6 & Agilent PTV - OD 3 mm (ID 2 mm); length 71 mm
CIS 4/6 with GERSTEL TDU/TD 3.5+ - OD 3 mm (ID 2 mm); length 78 mm
CIS 3 with TDU - OD 3 mm (ID 2 mm); length 78 mm
CIS 4/6 with TDU - OD 3 mm (ID 2 mm); length 78 mm

Straight with notch, deactivated or non-deactivated

  • For initial system evaluation
  • Recommended for splitless injection
  • Can be used for custom packed liners
  • Maximum temperature deactivated liner: 275°C
  • Maximum temperature non-deactivated liner: 400°C

 

Straight without notch, non-deactivated

  • For special uses e.g. in combination with TDS
  • Enables analyte trapping on the column
  • Maximum temperature: 400°C

 

Baffled, deactivated or non-deactivated

  • For cold split injections, baffles create good mixing of sample and carrier gas
  • Deactivated liner for liquid injections of moderate/high boilers and for labile compounds
  • Non-deactivated liner for liquid injections of stable and unproblematic moderate/high boilers
  • Maximum temperature deactivated liner: 275°C
  • Maximum temperature non-deactivated liner: 400°C

 

For SPME ID 1 mm, deactivated

  • Maximum temperature: 275°C

 

Siltek coated baffled liners, deactivated

  • For cold split injections, baffles create good mixing of sample and carrier gas
  • Siltek coating withstands high temperatures up to 350°C
  • Suitable for labile compounds

 

Packed with silanized glass wool, deactivated

  • Suitable for large volume injections into the CIS
  • Large surface area helps retain analytes while solvent evaporates
  • Packing acts as a filter for particulates
  • For liquid injections of moderate/high boilers, stable compounds
  • Maximum temperature: 275 °C

 

Packed with quartz wool,deactivated

  • Suitable for large volume injections into the CIS
  • Large surface area helps retain analytes while solvent evaporates
  • Packing can act as a filter for particulates
  • More inert than glass wool
  • For liquid injections of difficult compounds (acidic, alkaline etc.)
  • Maximum temperature: 275°C

 

Packed with glass beads,deactivated

  • Suitable for large volume injections into the CIS
  • Usage similar to the glass wool liner, but the glass beads provide a larger surface area and better retention of low boilers
  • Packing can also act as a filter for particulates
  • Maximum temperature: 275°C

 

Packed with Tenax TA

  • For PTV injection combined with solvent venting during large volume injections
  • Low affinity to methanol and water (Best water elimination at 40°C)
  • Usable for trapping from C5 to C26
  • Particularly suitable for headspace analysis
  • Maximum temperature: 350°C

 

Packed with glass beads and Carbotrap C

  • For trapping of analytes over a wide boiling point range in combination with large volume injections or headspace analysis
  • Maximum temperature: 400°C

 

Packed with PDMS foam

  • For trapping of non polar analytes covering a wide range of volatility up to n-C40
  • Well suited for large volume injections
  • Maximum temperature: 300°C
  • Minimum temperature: -10°C (glass transition temperature)
  • 5 mm packing length for semi volatiles
  • 10 mm packing length for intermediate volatiles
  • 30 mm packing length retains very volatile analytes

 

 

Adsorbent Properties

Tenax TA is a is a porous material based on 2,6-diphenylene oxide polymer, with a specific surface area of 35 m2/g. The material has a low affinity for water and methanol and can be used to trap and thermally desorb compounds in the C5-C26 range. The particle size is 60/80 mesh.

Carbotrap B has a mesh size of 20/40 mesh, with a specific surface area of 100 m2/g. This adsorbent is especially suited for trapping and thermally desorbing compounds in the range from C5 to C20 (depending on the structure of the molecule).

Carbopack C has a mesh size of 20/40 mesh with a specific surface area of 10 m2/g. This adsorbent is especially suited for trapping and thermally desorbing compounds in the range from C9 to C30 (depending on the structure of the molecule).

The GERSTEL Polydimethylsiloxane (PDMS) foam has an open porous structure. It is suitable as a trap or “guard column”. The highly inert and non polar material is well suited for large volume injections with analytes covering a wide range of volatility. PDMS provides strong retention of non polar analytes. Can be used for analytes as high boiling as n-C40. Ideal packing if glass wool trapping is too weak and Tenax TA too strong. Allows trapping at moderate temperatures, reducing the need for cryogenic cooling compared to glass wool. Maximum temperature: 300°C. Minimum temperature -10°C (glass transition temperature).
