Technical overview of the PerkinElmer Clarus 680 gas chromatograph with dual‑channel, programmable flow control and fast temperature programming.
The Clarus 680 gas chromatograph from PerkinElmer features a dual‑channel design and a fully programmable pneumatic control (PPC) system, allowing precise pressure, flow‑rate and split‑ratio settings. Its touch‑screen interface supports multiple languages and provides intuitive graphics for method development and monitoring.
The instrument offers rapid temperature programming with a heating rate of up to 140 °C/min and cooling from 450 °C to 50 °C in under 2 minutes. A variety of detectors (FID, FPD, ECD, NPD, TCD, PID) can be configured, and the built‑in liquid auto‑sampler supports up to 108 samples and large‑volume injections.
