Summaries
The CDS-7000E was acknowledged as a workhorse in the industry for decades as the most cost effective Purge and Trap concentrator. The 7000 E features our patented foam sensor, a newly redesigned wet trap for moisture control, and our original exchangeable sample pneumatics system, all providing the highest available performance and unrivalled chromatographic 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
The 8 port high temp valve offers unique capability to isolate wet trap during desorption step, which improves the efficiency of the moisture management.
Optional Soil Transfer Line
7000E comes with standard sample transfer line to interface with any GC system. The optional soil transfer line is available to expand the 7000E to be a concentrator for headspace
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 Vesels
The 7000E is capable of handling both 5 ml and 25 ml sample volume; depending on the sensitivity requirement of your analysis
Powerful and User-Friendly PC Interface
The powerful windows based software gives full access on the purge and trap parameter settings.
Optional Electronic Programmable Flow Control
With the electronic flow controller, the gas flow rate could be individually set within different purge and trap steps. For example, the flow rate could be increased in bake mode to improve GC resolution while maintaining a different flow rate in purge mode.
