Gas Chromatograph ppm to low ppb SULPHUR analysis using a Flame Photometric Detector Features The new NovaCHROM 5000 GC contains the latest GC technology based around the industry proven double Flame Photometric Detector (FPD). This sulphur selective detector, of which AGC Instruments has extensive experience, is ideal for characterising and quantifying a wide range of low level sulphur species in gaseous streams. Utilising the latest advanced technologies, this GC provides customers with the precise results they require with the ease of use and support features expected. The NovaCHROM 5000 detects and identifies individual sulphur species as opposed to total sulphur values and there is no interference from matrix gases which occurs in spectrometry analysers. Multiple column ovens, with heated valves to eliminate cold spots, are combined with passivated tubing to maximise sensitivity and achieve ultra low ppb levels. As a result, quick analysis times are achieved of between one to five minutes typically. AGC Instruments will custom design an analytical solution to meet your application. All systems are constructed using pipework not exceeding 1/8” in diameter and using only Swagelok® stainless steel fittings. The flow paths are contamination free and allow a fresh sample to reach the detector with speed. This is coupled with the ability to purge the valves and column ovens with an inert gas. Teflon tubing and heated lines are employed where necessary as well as flame-off and flow restrictor safety features. Furthermore, the NovaCHROM 5000 can be used with Natural Gas and ATEX versions are available upon demand. Measurements are achieved with ease and with minimal training required using the new interactive touch screen. The new Electronic Pressure & Flow Management System has ensured all functionality is easy and accessible also. The constant monitoring of critical status information such as flows, pressures and temperatures is readily available to the operator and is backed up with the Alarm activation function. This allows feedback locally to other locations such as the Control Room or DCS. As a result, this robust system ensures a consistent performance with excellent stability, sensitivity and a long working life.

Principle Of Operation The AGC NovaCHROM 5000, uses a double Flame Photometric Detector (FPD) which is designed to give a selective response to sulphur (or phosphorous) compounds. When an excitation energy is applied to the atoms of an element, a photometric emission spectrum is obtained whose wavelength is characteristic of the element. The intensity of the emitted light is proportional to the number of excited atoms. Within the flame photometric detector, the excitation energy is derived from the dual-heat zone combustion of the sample in a hydrogen-rich flame. This double flame...
