July 7, 2010 - The Servomex SERVOPRO Plasma on-line analyser measures trace nitrogen in argon or helium.Using Servomex’s plasma emission detector to provide an accurate, highly stable and reliable measurement, the Plasma can continuously measure Nitrogen in pure Argon for Argon production in cryogenic air separation plants, and can also be configured to measure Nitrogen impurities in pure Helium and Argon for gas bottling applications and specialty gas laboratories.The Plasma offers users a wide and highly accurate measurement range, with three standard ranges of 0-1ppm, 0-10ppm and 0-100ppm and an automatic ranging feature that changes the measurement parameters for optimal output resolution.
Other ranges are available from Servomex on request, with the exceptional sensitivity and accuracy of the Plasma’s measurement capabilities illustrated by a lowest measurement range of just 10ppb resolution/ 2 ppb noise.A microprocessor platform offers new ethernet and internet connectivity which greatly increases remote communication options when compared to the Plasma’s predecessor, the KA k2001. The Plasma can now be remotely controlled via a network or an internet browser, allowing operators to check all parameters or troubleshoot the unit offsite. The unit can also be calibrated to be manually driven by a remote monitoring system for troubleshooting, with a standard 4-20 mA output included to transmit process values to a remote system.
Operational safety is also increased and potential downtime further minimised by new fault alarm and contact alarm systems.With no moving parts and programmable auto calibration, the Plasma’s maintenance-free design offers exceptional ROI and low cost of ownership for users. Alongside the improved measurement capabilities and communication options, the SERVOPRO Plasma is the ideal analyser for a range of industries and processes including ASU production, Argon purification plants, speciality gas laboratories, process control, chemical plants, gas management systems, welding gas control, Helium liquification plants, truck loading and pure gas bottling.
