Online Analyzers

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
