The Varian 490-GC PRO is a micro gas chromatograph used for process monitoring. It offers repeatable, fast, and accurate monitoring capabilities. It allows for data collection, data integration, and result transfer via industrial communication protocols, enabling quick and accurate process monitoring and control. The product does not use flammable gases and requires only small quantities of sample gas for analysis and monitoring, contributing to operational safety. With its high measurement accuracy, it can be used for various industrial applications such as refinery gas composition and trace detection of components.
The Agilent 490-GC PRO Micro-GC is designed for fast, accurate, and repeatable monitoring of industrial processes. It supports up to four independent channels and can be used for applications ranging from refinery gas composition to component trace detection at parts per billion levels. The instrument features in-board data handling, allowing for unattended, round-the-clock measurements without the need for a local operator.
The device utilizes a micro-machined Thermal Conductivity Detector (TCD) and offers various carrier gas options including Helium, Hydrogen, Nitrogen, or Argon. It is housed in a 19-inch rack format and supports industrial communication protocols such as Modbus and TCP/IP for integration into existing process control systems.
