Sulphur and nitrogen process analysers

December 2007 Analytical Instrumentation & Environmental Monitoring

Antek Instruments' 6200 Series from OEN Enterprises, consists of sulphur and nitrogen process analysers, utilising pyro-fluorescent sulphur and pyro-chemiluminescent nitrogen technology to provide fast, precise measurement of liquid, LPG and gas samples. With a 250 ppb range the analysers have a programmable cycle time from 2,5 to 15 minutes per stream and built-in dual range and multistream capabilities. No environmentally hazardous catalysts, reagents, tapes or other wastes are utilised, nor is a radioactive licence required.

The highly reliable six-port rotary injection valve is isolated from electronic components, yet easily accessible for routine maintenance. A membrane dryer thoroughly removes moisture before the sample enters the detector and the built-in pressure regulators ensure dependable flow of utility gases.

A realtime on-screen view of the analysis progress is possible and a touch-screen provides access to calibration, validation, alarm and troubleshooting features.

Three types of analysers are included in the Series. The nitrogen model is designed for rapid analysis of liquid or gas samples for totally chemically bound nitrogen, while the sulphur model is designed for rapid analysis of liquid or gas samples for total sulphur. The third type is a combined nitrogen/sulphur analyser.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
