CDS Analytical 7000C Purge & Trap Concentrator
In Stock
The CDS 7000C supports purge & trap workflows commonly used in environmental laboratories performing EPA‑aligned VOC and SVOC analyses. The 7000C provides the performance, temperature control, and reproducibility required for:
- EPA Method 524 (VOC in drinking water)
- EPA Method 624 (VOC in wastewater)
- EPA Method 8260 (VOC/SVOC by GC/MS)
Description
The CDS Analytical 7000C Purge & Trap Concentrator is a lightweight, space‑efficient system engineered for VOC and SVOC sample preconcentration prior to GC/MS analysis. With 0–999.9 minutes of programmable timing, high‑temperature desorption, and a proprietary Type X adsorbent trap, the 7000C delivers reliable, high‑sensitivity performance for environmental, industrial, and regulatory testing laboratories.
Its compact footprint makes it ideal for labs requiring purge & trap capability without the size or weight of larger concentrators.
Available from Alliant Scientific, an authorized CDS Analytical distributor, supplying the CDS Analytical 7000C Purge & Trap Concentrator with full support for system configuration, installation.
Flexible, Programmable Purge & Trap Control
The 7000C offers fully programmable timing from 0 to 999.9 minutes, allowing precise control over purge, dry purge, desorb, and bake cycles. This flexibility supports a wide range of sample matrices and method requirements.
High‑Temperature Desorption & Heated Pathway
The system features:
- Desorption trap temperature up to 425°C
- Wet trap temperature up to 425°C
- Valve oven up to 350°C
- Heated transfer line up to 350°C
These high‑temperature capabilities ensure complete analyte recovery and minimize carryover.
Proprietary Type X Adsorbent Trap
The Type X trap provides broad retention characteristics for VOCs and SVOCs, making the 7000C suitable for environmental water testing, soil extracts, and industrial applications.
Compact & Lightweight
Weighing only 9.5 kg, the 7000C is one of the most compact purge & trap concentrators available, ideal for labs with limited bench space or mobile/field‑based setups.
