Spark CH4

Spark CH4, offers powerful advanced spectroscopy for a range of applications, from process control to quality and safety assurance in Air Separation Plants.

Other applications include monitoring of cylinder filling, bulk delivery and distribution transfer points, as well as welding, medical, industrial and high-purity gas production, and more. Sensitivity as low as 6 ppb with full range measurement as high as 80 ppm CH4 makes the Spark an ideal solution for these applications.

There is no need for calibration, spare parts, limited measurement ranges, and worries about drift and downtime usually associated with NDIRs. And without the need for H2 fuel gas and with plug-and-play installation within minutes, the Spark CH4 is a faster and safer alternative to FIDs. 

Features:

  • Powerful, proven Cavity Ring-Down Spectroscopy (CRDS) technology
  • Drift-free measurement
  • Increased laboratory safety without the need for fuel gas
  • Self-tuning and auto-calibration
  • Extremely low Cost of Ownership
  • Ethernet, 4–20 mA and RS-232 connectivity
  • Fast response with low gas consumption
  • CH4 analysis over a vast range: 6 ppb to 50 ppm (in O2)

Applications

  • Air Separation Units & Nitrogen Plants
  • Gaseous CRMs & Calibration Gas Mixtures
  • Semiconductor
  • Medical gases
  • High-Purity (UHP) Gases & Systems
  • Hydrogen Fuel Cells
  • Research & Development

Process Insights also offers a new CRDS analyzer performance upgrade, the Speed+™ Analyzer Performance Upgrade Software adjusts your analyzer’s response automatically and in real-time to deliver the best performance.  Benefits of Speed+ for your operations include real-time process control to ensure quality, as well as faster throughput and increased capacity to improve efficiency and profitability.

Serani™ Max Analyzer Interface Software allows you to have remote access from your computer or laptop for our latest CRDS generation analyzers, such as the Halo KA Max and T-I Max. The Windows-based software package communicates with the analyzer through Ethernet and allows control of the system conveniently from your desk.
