The 7000C delivers the same combination of quality that made the 7000E such a reliable instrument, but with plug and play connectivity to the worlds leading autosampler platform - the CTC PAL Robotic systems. The 7000C features our industry standard foam sensor, a newly designed wet trap and our distinguished exchangeable sample pneumatics systems, all providing the highest available performance and unrivaled chromotographic resolution. 

Product Features
Valve Oven Reaching as High as 350 °C

This industries highest programmable valve oven expands the capability from VOC's defined in EPA 8260 into the sVOC range 

8 Port High Temp Valve

Unlike other brands, CDS adopts 8 port valve to offer a unique capability to isolate the wet trap during desorption step, which improves the efficiency of the water management.  

Plug and Play Connectivity with CTC PAL

The plug and play setup for the 7000C with CTC PAL autosampler is quickly adding Purge and Trap capability to your system. 

Hydroguard Wet Trap

The newly designed wet trap is coated with Hydroguard for optimized moisture control with maximized life span 

Quick Access Panel 

The quick access panel offers a convenient way to maintain the sample pathway to minimize any service downtime

Patented Foam Sensor 

This patented sensor eliminates the possibility of sample foaming and subsequent contamination of the sample path way.

Compatible with 5 ml and 25 ml Sparge Vessels

The 7000C is capable of handling both 5 ml and 25 ml sample volume, depending on the sensitivity requirement of your analysis

Optional Heated Sparge Vessel

The heated sparge vessel adds two folds of value to the system; purging at an elevated temperature to improve sensitivity, and reducing carryovers to help keep the sample path way clean.

Acquisition Software with Boosted Productivity

The 7000C Purge and Trap plugin is seamlessly integrated to the CTC control software and method editor. 

Optional Internal Standard Module

This optional module comes with two independent 5 ml reservoirs for an delivery of 2 µl internal standard and/or surrogate to the sample.  

Optional Hot Water Rinse Module

The hot water rinse module is designed to rinse the sample path way in both the CTC PAL and 7000C system to reduce carryover.
