2 If gas chromatography plays a role in your daily operations, you already know CDS Analytical as the world s leading manufacturer of pyrolysis instrumentation. What you may not know is that CDS has been producing Purge & Trap instruments for a quarter century first under the name Peak Master and later through an exclusive OEM relationship with a major U.S. supplier, in fact, you might already have one in your lab! Today the CDS 7000 E Purge & Trap is available directly from CDS, giving customers everywhere direct access to the best chromatographic resolution in the industry. Gases Water Analysis: EPA Method The CDS 7000 Purge & Trap The CDS 7000 was acknowledged as a workhorse in the industry for years, now the 7000 E delivers the same combination of qualities that made the 7000 such a workhorse, but in a smaller and more cost effective package. The 7000 E features our industry standard 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. Internal Electronic Flow Control Option The 7000 E Purge & Trap can be purchased with or without Electronic Flow control. The ability to vary the flow in each step of the process (purge, trap dry, trap desorb and trap bake) can result in increased throughput for each sample batch. However, some regulators will not allow you to use variable flows, so CDS has made it an option.
