TITAN XL Large Volume PTV GC Inlet

Traditionally, GC injections have been limited to 1µL.  Larger injections create chromatographic issues by overloading the inlet and the column.  The TITAN XL was designed to overcome these limitations by introducing Large Volume Injection (LVI) to a standard GC or GC-MS system.  The TITAN XL's use of PTV allows it to make LVI injections up to 1000µL while maintaining the ability to inject traditional 1µL split/splitless volumes used with a standard GC inlet.  


  • Universal GC inlet that provides split/splitlesTITAN XL Installeds and large volume injection in a single inlet.

  • Proprietary coil and cartridge heater gives the TITAN XL the ability to reach an elevated temperature in short periods of time
  • Sample path coated in Inertium to reduce breakdown and eliminates carry over
  • Useful for a wide range of applications including wastewater extracts, food extracts, pesticides and PAH
  • Peltier Cooling Unit (PCU) eliminates the need for cryogenics while still allowing for sub-ambient and sub-zero temperatures 
  • Compatible with both the Agilent Technologies 6890 and 7890 gas chromatography

Peltier Cooling Unit (PCU)

In Large Volume Injections (LVI) the inlet temperaturPCU 1000 x 760 (1000 x 760)e starts at ambient or sub-ambient temperatures depending on the boiling point of the solvent. The ability to cool the inlet down to these reduced temperatures is often done using LN2 or LCO2. Cryogenic gases are expensive, consume large amounts of floor space and require the laboratory to add additional safety measures. In contrast, the Peltier Control Unit (PCU) from ASAP Analytical is low cost, has a small footprint and requires no other safety measures. The PCU can be programmed to begin cooling after an injection has been made to decrease the cycle time between sample runs. This critical feature helps labs to increase productivity and lower cost per sample. When installed in combination with the TITAN XL, labs can see immediate benefits in cost reduction, flexibility, and reductions in cycle time.

The TITAN PCU is compatible with other GC inlets including the Agilent MMI and Gerstel CIS.
