AQUATek LVA – Water Autosampler

The AQUATek LVA is a full automation solution for routine analysis of waters by purge and trap concentration.It utilizes a fixed volume loop that is filled with liquid sample, internal and/or surrogate standards are added, and then the sample is transferred to the Lumin or Stratum PTC. Upon completion of the purge step by the concentrator, the AQUATek LVA then initiates a clean up cycle where the sample loop and concentrator sparger are cleaned with 90°C water via the two-stage water heater.

Description

The AQUATek LVA is a full automation solution for routine analysis of waters by purge and trap concentration. It utilizes a fixed volume loop that is filled with liquid sample, internal and/or surrogate standards are added, and then the sample is transferred to the Lumin or Stratum PTC. Upon completion of the purge step by the concentrator, the AQUATek LVA then initiates a clean up cycle where the sample loop and concentrator sparger are cleaned with 90o C water via the two-stage water heater.
The AQUATek LVA offers all the capabilities you need for compliance with USEPA Methods for the analysis of aqueous volatile organic samples, including a true closed-system technique for sample handling and vial cooling. The closed-system sampling technique and vial chiller ensure the integrity of the sample during the sample preparation process, greatly minimizing volatile organics loss as well as reducing labor cost.
