benefits of mks-precisive on-line process analysers

Tried and tested in some of the harshest field environments, MKS-Precisive aims to develop real-world solutions for the environment you work in. This technology has resulted in astounding benefits:

  • Built in, permanent span analyser calibration
  • Real-time response for analysis
  • Wide variety of gases can be measured from ultra violet, near infrared and infrared spectrums
  • Remote and completely unattended operation
  • Multi-compound detection
  • GC-like speciation
  • High sensitivity (can measure ppb, ppm, %)
  • Excellent linearity and stability
  • Wide operating and sample gas temperature performance
  • Through-mode analysis of gases and liquids (no sampling)
  • Extremely robust design
  • No calibration or carrier gas, no consumables
  • Less than half the cost of traditional GC-based systems

Quantitative analysis of alkane gases specifically C1 to C5 (methane, ethane, propane, butanes and pentanes) are important in a variety of applications, including BTU measurement and quality analysis of natural and biogas products. The predominant technique until now has been Gas Chromatography (GC) given the ability to separate individual compounds with high selectivity. Alternative approaches have included calorimeter (also referred to as residual oxygen) based platforms but these are often very expensive and require extensive maintenance and servicing.

patented tunable filter spectroscopy

MKS-Precisive’s online and real-time infrared gas analyser employs an innovative all-optical technology that has the sensitivity and specificity required to provide a solution that is as effective, more efficient, and with significantly lower cost of ownership than traditional GC-based monitoring systems.

The hardware platform is based upon patented Tunable Filter Spectroscopy (TFS) providing fast, rugged and high-precision spectral scanning in the ultraviolet, visible and infrared wavelengths. The stand-alone analyser enables measurement of the individual C1-C5 species in various fuel vapours including natural gases and alternative fuels with 0.01% measurement resolution and high selectivity.

As the table below shows, there are several notable qualities of a TFS-based analyser. Applications that align well to the TFS approach include:

  • Power system balancing and control (Turbine optimization & Fuel Cells)
  • Pipeline & Custody transfer
  • Refinery gas analysis
  • Combustible gas monitoring

The new TFS-based approach yields a technique that is often as effective analytically as GC but significantly more efficient due to lack of analyser calibration infrastructure with associated gas cylinders.
