High Reliability with TDL O2 Analyzer

When explosion risk is a concern in production tanks, oxygen sensor accuracy and response speed are critical. Mettler Toledo's GPro® 500 delivers high performance with nearly zero maintenance requirements for a leading performance additive manufacturer.

Safety Comes First

Phosphorus pentasulfide is an inorganic compound used in the production of lubricants, pesticides and flotation agents. As an extremely flammable substance, an inert atmosphere must be maintained during its production. A closed extractive measurement system and paramagnetic analyzer can be used to monitor O₂ levels in production line equipment. Maintaining the moisture content in the gas sample at very low levels prevents negative effects on the analyzer's response time and performance.

Italian Company Needed Fast and Accurate O₂ Measurement

Italian company Italmatch is a leading manufacturer of performance additives used in the lubricant, plastics, water and fuel sectors. At its Spoleto facility, it required an advanced oxygen analyzer and sampling system to reduce measurement time and increase measurement accuracy in phosphorus pentasulfide production.

Advanced Technology Ensures Measurement Accuracy and Confidence

Tunable diode laser (TDL) gas measurement analyzers use a laser beam tuned to a specific frequency to rapidly detect the amount of target element in a gas stream. Mettler Toledo's growing GPro 500 analyzer series enables TDL to be offered with a wide range of process adaptations. This gives the series great flexibility in terms of application compatibility and installation options. The GPro 500 requires no maintenance except annual verification and periodic cleaning of the analyzer optics; therefore, these analyzers can be relied upon to provide continuous and reliable measurements throughout production processes. The GPro 500 can be installed in situ when process conditions permit, or connected to an extraction system when there is a high particulate load or humid content in the gas stream, as is the case at Italmatch.

Six Months Without Maintenance

The GPro 500 demonstration at Italmatch's Spoleto facility convinced the operations team of the analyzer's ease of use, fast response and low maintenance requirements. Additionally, the team appreciated the two alarm thresholds on the connected M400 transmitter, which signal when a low or high O₂ level violation occurs in the production equipment. This was something not possible with the paramagnetic analyzer. A GPro 500 with extractive cell adaptation was installed in a new extraction system. Since the GPro 500 was commissioned at the Spoleto facility, the plant has been highly impressed with the measurement accuracy, fast measurement and trouble-free operation. Facility Manager: "I am very satisfied with the analyzer's performance. The installation was surprisingly easy, and since we installed it six months ago we have not experienced any downtime. I wish we had discovered this years ago." At Italmatch, confidence in the accuracy of O₂ level information in the production tank has been fully and unequivocally established.   Tolga Baydili Senior Sales Representative Process Analytics Division Mettler Toledo Turkey
