Main 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

The autosampler is equipped with a 5 ml reservoir for internal standard addition.

5 mL and 25 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.

Dynamic Headspace

The 7450 is equipped with a soil tower for dynamic headspace sampling in compliance with EPA 8260 soil samples.

Water station

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.

Magnetic stirrer

The magnetic stirrer drives the magnetic bar in the soil vial based on EPA 5030 and 5035 sampling requirement for soil samples.

PEEK Sample Pathway

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

Powerful PC Interface

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

Gripper with Optical Sensor

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.

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 to 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.
