Overview

This chapter gives you an overview of the NIR-MS-2000-C2F’s features, the

control panel and display unit, and a description of the operation.

The NIR-MS-2000-C2F Flour Analyser has been developed in Australia for

use by flour millers and grain processors, for measuring protein, moisture and

oil in grains and oil seeds as well as protein, moisture, water absorption and

starch damage in flour.

The NIR-MS-2000-C2F is a full spectrum NIR spectrophotometer. The NIR-

MS-2000-C2F uses a linear array detector and a spectrograph to provide the

NIR transmittance spectrum from 720 –1100 nm. Within this region of the

electromagnetic spectrum compounds such as protein, moisture, oil and

carbohydrates absorb infrared energy. By measuring the intensity of the

infrared energy that passes through a glass cell filled with grains, each of the

components can be measured.

The NIR-MS-2000-C2F has been designed to provide the following features:

• Grain Identification;

• Automatic Instrument Calibration;

• Spectral Matching;

Analysis Software

Your NIR-MS-2000-C2F comes ready to use, with all internal software

installed and calibrated. This internal software allows you to collect spectra and

analyse it to get protein, moisture, oil and other component readings. A serial cable

and interface software are provided for use with a computer so that data can be

uploaded from the NIR-MS-2000-C2F. A USB Memory device is supplied as a

means of uploading and downloading calibrations and data files.

A more extensive software package, NTAS, is available to allow greater

control of calibrations and data analysis. NTAS provides a Windows 95, 98, 2000

and XP Professional interface to the NIR-MS-2000-C2F allowing visualisation and

data manipulation of spectra collected from the field or in the lab.

Figure 1. provides a schematic of the optical and electronic layout of the analyser.

Light from tungsten halogen lamp is shone through a sample cell holder, focusing

optics and into a flat field spectrograph and then onto a silicon photodiode array

detector. The amount of light passing through the optics is measured by the detector

and stored in the internal computer’s memory. This is referred to as the “100%

reference” reading. A sample of grain or oil seeds is loaded into a sample cell, that is

placed into the sample cell holder. The amount of light passing through the sample is

measured by the detector and stored into the internal computer’s memory. This is

referred to the “sample scan”.

The calibration models for each product are stored in the instruments memory chip.

The computer board applies the calibration model to the “sample scan” and

calculates the protein and moisture, or oil and moisture values for the sample.

Principle of Operation:

Protein, moisture, oil and starch absorb NIR energy (light) at specific frequencies

(wavelengths = nm), ie, protein – 1020nm, moisture – 970nm, oil – 910nm and

starch 820nm. The NIR spectrum of the sample, shown in figure 3, represents the

amount of light absorbed at each wavelength, which is proportional to the

concentration of each component. A calibration model is stored in the internal

computer’s memory for each component, eg, protein and moisture, for each product,

eg, wheat, barley etc.

To analyse a sample, the instrument collects the NIR spectrum for the sample, and

the computer applies the calibration model and computes the % protein and %

moisture.

During the warm up period, the lamp is powered up and allowed to stabilise for a set

period of time, approx. 15 seconds. The instrument then measures the energy level

for the lamp. The 100% light level is recorded in the computers memory.

Once the instrument is calibrated, the LCD screen will prompt for the sample cell to

be loaded.

Take the appropriate sample cell (16 mm for wheat) and fill the cell above the

window and almost to the top. Also, note that the sample cells must be loaded in only

one direction. The gear teeth on the side of the cell must be facing the back of the

sample cell chamber. Once the cell has been pushed into the sample chamber the

motor will be activated and the cell will move down into five positions and then

come up into five positions.

For each position the constituents are calculated and displayed on the screen. When

all 10 scans are completed, the average of the results will be displayed.

Should the results be outside the ranges specified in the calibration, the screen will

display a message that the grains analysed are not consistent with the calibrations for

the selected product. Check that the correct product was selected.

Operations Manual

Bias and Slope Adjustment

Each calibration has one or several components, eg, protein, moisture and fat. Each

of these component calibration models have a Bias and Slope adjustment facility.

The Bias and Slope can be adjusted in order to correct the calibration to some

reference method of analysis for each component, ie, Kjeldalh for protein, Oven

Drying for moisture and Soxhlet Extraction for fat.

Bias adjustment is where all samples read high or low by a constant

amount. The average difference between the NIR readings and

reference readings = the Bias.

As shown above the NIR anlayser is reading 0.5 lower than the reference

method. As such, 0.5 is added to the existing bias to bring the NIR analyser

into alignment with the reference method.

Slope and Bias adjustment is where some samples read high and some

read low as compared with the reference readings. The Slope and Bias

is calculated by plotting the NIR Analyser readings vs the reference

readings in Excel. By adding a trend line in Excel to the plot, the Slope and

Bias can be taken from the equation shown.

Outlier Detection

This feature checks each scan and the results to see if they are consistent with the rest

of the results. If the software detects an “Outlier” it will reject the results and not

include the specific results in the averaged results.

There are two outlier detection methods;

1) Z Scores: uses a statistical calculation to detect results greater than 1.5 times

the standard deviation from the mean of all the scans.

2) Min Max: simply rejects the lowest and highest results.

Select either method or select 3) None for no outlier detection.
