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 90^o 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.

Applications

VOC sampling and analysis are used in a wide range of applications in the following industries:

Environmental
Food and Beverage
Pharmaceutical
Flavor and Fragrance
