New optical natural gas pipeline-applicable oxygen analyzers employ bio-tech, O2-sensitive fluorescence quenching technology

 

OXY4400 optical oxygen analyzers are introduced for natural gas pipelines.

They employ fluorescent quenching, a proven new bio-technology declared to eclipse conventional oxygen measurements in natural gas pipelines.

The technology uses a sensor (optical probe) that contains an indicator dye sensitive to O2. The dye is optically excited by an LED light source. Fluorescence emission of the indicator dye decays at a known rate, but if oxygen is present, an energy transfer occurs and “quenches” the fluorescence.

Fluorescent quenching is said to offer advantages over traditional measurement to include greater accuracy, much faster response, simplified calibration, and practically no maintenance.

OXY4400, with this new technology is especially applicable for areas with high H2S concentration including sour gas monitoring, production areas, or pumping stations, declares the manufacturer. In natural gas operations the new analyzer functions as a compact, stand-alone, one-channel meter with LCD display and data logger.

The instrument uses a light source (LED), an optical sensor probe, and a photo detector. Pulsed light from the LED is sent down a fiber optic cable to the sensor probe (optode) where energy from the light is absorbed by an indicator dye. The light (fluorescence emission) is sent back through the cable to the photo detector where it is converted to an electrical signal that can be read. The amount of “quenching” is determined by amount of O2 in a stream. Resulting performance is said to be exact — with almost instant measurement down to 0.5 ppm.
