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.

Product Features
72 Position Autosampler

The autosampler comes with a high capacity of 72 positions for 40 ml VOC vials in three separated racks. 

Internal Standard Addition

CDS purge and trap autosampler adopts a unique 10 port valve with micro-loop technology to precisely inject 2 micro liter of internal standard into the sample, which guarantees the RSDs under 3%. 

5 mL and 10 mL Sample Loop

Depending on the sample size from the Purge and Trap concentrator, the autosampler could accommodate both 5 mL (default) and 25 mL (optional) sample transfer.  

Precision Robotic Arm

The position accuracy of the 2nd generation autosampler is improved by 50% to 1 mm (X, Y and Z) 3D placement accuracy due to a high precision drive mechanism

Ease of Alignment

The alignment calibration has been significantly improved in the 2nd generation autosampler. The user friendly software tool helps make alignment calibration in under 10 minutes.

Longer Life Expectancy

The 2nd generation autosampler comes with a SMART acceleration control to lower the impact on the driving mechanism by 40%. This extends the life of the system due to less strains. 

PEEK Sample Pathway

The chemically inert sample pathway guarantees the success of your purge and trap testing even with challenging liquid samples.

Powerful and User-Friendly PC Interface

The PC software has a friendly interface to configure each run with programmable rinses, programmable blanks and internal standard addition.

Multiple Aliquots

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.
