Precision by Design: Horizontal Sample Introduction
Unlike vertical combustion systems, the CE440 features a unique horizontal sample introduction system that virtually eliminates sample residue and carryover. This innovation ensures improved baseline stability and greater consistency between runs, reducing the risk of contamination and improving long-term accuracy. Samples are combusted in a pure oxygen environment, breaking them down into measurable gases that are precisely detected and quantified using thermal conductivity detection. This system is especially beneficial for labs handling a diverse range of materials or requiring regular method changes, offering exceptional cleanliness and flexibility. The CE440 is compatible with a wide variety of sample types and sizes, including solids, liquids, powders, gels, and films. Capable of handling up to 2 grams of material, it delivers a wide analytical range, from trace to bulk analysis, with fast throughput and minimal downtime. With a simple, intuitive software interface, users can program sequences, monitor runs in real time, and analyse data with ease. Integrated diagnostics and real-time feedback help reduce troubleshooting and ensure reliable performance, even in high-throughput environments.
