Online Analyzers

Online analysis using Near-infrared Spectroscopy (NIRS) technology provides rapid and accurate monitoring of key parameters in refining and fuel blending, reducing the need for time-consuming and costly lab analysis.

SGS provides a full suite of NIR analyzer services, including equipment supply and installation, project start-up and technical support for in-laboratory application and on-line installation. We work in close cooperation with major equipment suppliers.

What is Near-infrared Spectroscopy (NIRS)?

Near-infrared Spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. It has wide range of applications for the oil and petrochemicals industries, including monitoring of:

  • RON, MON, benzene and aromatics content and RVP in reformat rundown streams
  • IBP and FPB, flashpoint, cloudpoint, CFPP in diesel during blending

The range of potential applications is constantly growing.

Advantages of NIR analysis

  • Provides test results of multiple parameters in just 20 seconds
  • Reduces the need for extensive sample preparation
  • Requires less manpower than conventional lab analysis
  • Eliminates the need for laboratory analysis and associated costs and delays
  • Does not require hardware changes if a product or formula changes
  • Ideally suited to support quality control processes

The SGS Near-infrared Analyzer Services (NIR) competence center

The center provides a full suite of services regarding NIR instrumentation, implementation, calibration and operation, including:

  • Supply of NIR equipment and NIR models
  • Start-up project management and execution
  • Calibration (either locally or through remote support from the SGS NIR competence center)
  • Back-up and support from qualified SGS laboratories in the area
  • Coordinated support with manufacturer(s) 

How we implement NIR

There are four basic steps for NIR implementation:

  • 1st step
    • Place NIR analyzer in your lab
    • Take spectra from products involved 
    • Perform lab analysis using validated methods
    • Send spectra and lab results to SGS NIR competence center
  • 2nd step
    • Development of models and installation through remote control/access of the NIR analyzer
    • Monitoring and comparison of real world samples 
  • 3rd step:
    • Regular correlation of NIR results against formal test results of real-life samples to provide essential input for updating the NIR calibration models
  • 4th step:
    • Develop and implement next steps to place NIR on-line
