What is a Calibration?

Calibration refers to the method employed by ProSpect for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

The calibration process begins once the initial setup of ProSpect is complete. A range of NIR spectrometer measurements and corresponding samples are collected from a variety of constituents. The samples are tested and the calibration values are entered into ProSpect.

During operation, ProSpect analyzes and displays the concentration in the current product for each constituent in the calibration. This information can then be sent to the PLC and used for automatic process control.

ProSpect calibration advantages:

  • Calibration developed and achieved with minimal number of samples
  • Minimal calibration maintenance required
  • Internal reference compensates for lamp decay
