CDS’s2nd generation Purge and Trap autosampler (water only) with improved precision.

The 7350 autosampler is a competitively priced, 72 position autosampler for EPA methods 524, 624 and 8260 waters, and built on our 2nd generation autosampler with a more precise handling for sample loading. A perfect match for the 7000 Purge & Trap concentrator.

Key features

72 positions autosampler for 40 ml VOC vials in three separated racks
Equipped with a 5 ml reservoir for internal standard addition
Accommodate 5 mL (default) and 25 mL (optional) sample transfer
Position accuracy is improved by 50% to 1 mm (X, Y and Z) 3D placement accuracy due to a high precision drive mechanism
Alignment calibration in under 10 minutes
Extend the life of the system by using SMART acceleration control to lower the impact on the driving mechanism by 40%
The chemically inert sample pathway guarantees the success of your purge and trap testing even with challenging liquid samples
The sampling double-jacketed needle could be configured to reach the bottom of the VOC vial to perform multiple aliquots runs from the same sample

CDS's 2nd generation Purge and Trap autosampler for both water and soil samples.

The 7450 autosampler is a 72 position autosampler with dynamic headspace sampling function for EPA methods 524, 624 and 8260 (both water and soil), and built on our 2nd generation autosampler with a more precise handling for sample loading. A perfect match for the 7000E Purge & Trap concentrator.

Key features

72 positions autosampler for 40 ml VOC vials in three separated racks
Equipped with a 5 ml reservoir for internal standard addition
Accommodate 5 mL (default) and 25 mL (optional) sample transfer
Equipped with a soil tower for dynamic headspace sampling in compliance with EPA 8260 soil samples
The soil tower is equipped with a water station to process water samples, and a separate needle is used for soil samples to prevent carry over
The magnetic stirrer drives the magnetic bar in the soil vial based on EPA 5030 and 5035 sampling requirements for soil samples
Position accuracy is improved by 50% to 1 mm (X, Y and Z) 3D placement accuracy due to a high precision drive mechanism
Alignment calibration in under 10 minutes
Extend the life of the system by using SMART acceleration control to lower the impact on the driving mechanism by 40%
The chemically inert sample pathway guarantees the success of your purge and trap testing even with challenging liquid samples
The highly reliable VOC vial gripper has an optical sensor as a safety measurement to give you peace of mind when transferring samples to the soil tower.
