Gas Chromatograph % and ppm analysis using a Thermal Conductivity Detector Features The new NovaCHROM 4000 GC is built on the platform of the successful AGC Series 100 TCD Gas Chromatograph. This versatile and robust detector design, of which AGC Instruments is a leading supplier worldwide, is ideal for permanent gas analysis and its universal applicability ensures that it is both cost effective and reliable. Utilising the latest advanced technologies, this GC provides customers with the precise results they require with the ease of use and support features expected. Thermal Conductivity Detector (TCD) Accuracy to <5ppm (application dependent) Fast Detector Response time of < 1 Ideal for Permanent Gas Analysis Versatile & Robust Detector design Universal Detector Cost Effective and Reliable The NovaCHROM 4000 GC uses an industry proven method of analysis for the quality control of gases: the Thermal Conductivity Detector (TCD). This detector is ideal for measuring impurities from % to ppm and minimal training is required. The interactive touch screen uses an easy-to-use user interface for guided functionality and this enables the operator to achieve guaranteed applications with ease. Therefore, the NovaCHROM 4000 GC provides a top class service to you at all times. Large Colour 6.5” LCD Touch Screen Long Term Stability & Sensitivity Electropolished Stainless Steel Tubing Integrated Configurable Alarms System Packed, Micro-Packed & Capillary Columns for Maximum Sensitivity 1/8” Stainless Steel Swagelok fittings are combined with Vici Valco high purity rotary valves to guarantee a contamination free environment that will provide excellent stability, sensitivity and a long working life. The AGC engineering design team will devise a solution specified to suit the application at hand. Furthermore, all systems can be designed for corrosive applications with corrosion resistant materials employed throughout. Independent Column Ovens with individual Temperature Control Integrated Diagnostics System Full Control by TrendVision PLUS Software Increased Connectivity with both USB, RS-232 and RS-485 Drop Down Front Panel for easy access to electronics

Principle Of Operation The AGC NovaCHROM 4000, using the Thermal Conductivity Detector (TCD), is typically used for the precise analysis of the components in multiple gas mixtures at percentage and ppm levels. The TCD has four sensing elements which are connected to form an electrical Wheatstone bridge circuit. These elements are typically miniature rhenium-tungsten filaments which are mounted in a metallic cell block. A flow through type thermal conductivity cell is normally used in this analyser. This cell contains a sample and reference gas flow geometry and two elements are installed in each...
