    5. Preparing the main unit * Clean the measurement window. If it is not clean, measurement may not be performed correctly. * When closing/opening the light shielding cover, be careful not to pinch the fingers. * Be careful of protrusion provided on the top plane or edges of the main unit. Otherwise, it may cause an injury, etc.

Selecting the sample cell (container) According to the form of the measuring sample, select a sample cell from four types listed in the following. * Make sure that the selected one fully covers the measurement window. Also, use the same one in making calibration curve and actual measurement. * When measuring the liquid sample, be careful not to spill on the unit. 1.

    6-2. Deciding whether to use the light shielding cover The light shielding cover can avoid effects from external light. It is preferable to use the cover in order to avoid external light. * Perform measurement closing the light * The cover may not be usable depending on the shielding cover if possible. sample cell or sample form. In the case of not using the cover, it can be removed.

    6-4. Setting the sampling amount Put the sample in the sample cell selected in section 6-1 and measure the absorbance to determine the sampling amount. * If the sampling amount (sample height) is not consistent, it may affect the absorbance. * When not using the light shielding cover, determine the sampling amount under the same condition of external light as measurement.

  • Page 14: Making The Calibration Curve

    7. Making the calibration curve ● Necessity of calibration curve The NIR Composition Analyzer measures the near-infrared absorption of the measuring object, and converts the obtained data to the percentage of composition.Therefore, a conversion formula that calculates the actual composition from the near-infrared absorption is required. This is called "calibration curve". The calibration curve differs depending on the measuring object. Therefore, it is required to make calibration curve per object in advance. This unit is capable of making calibration curve easily using the supplied PC software. 7-1. Setting the measurement range and the number of samples Set the composition to measure and the number of samples required for making calibration curve. The samples with different composition percentages that fully covers the measurement range are required.

  • Page 15: Moisture Preparation

    7-4. Moisture preparation In the measurement of moisture content, if samples to fully cover the measurement range cannot be prepared in the regular moisture control process (drying or adding water), prepare the samples by moisture preparation. To derive a sample with different moisture by moisturising or drying a source sample is called "moisture preparation". There are various ways to change the moisture content, such as spraying water using an atomizer or drying the high moisture content sample. Make samples with different moisture by selecting an optimum method according to the measuring object. Also, when samples are made by moisture preparation, it is recommended to wait five to seven days until added water is well soaked to obtain better consistency of moisture. Then, perform...

  • Page 18: Zero-Adjustment

    9. Zero-adjustment ● What is zero-adjustment? If errors occur in the measurement results due to light source consumption or other causes, read the absorbance obtained from reflection on the zero-adjustment plate. The measurement result will be stabilized by setting the absorbance as zero. Make sure to perform this operation when making calibration curve or in the regular measurement as well.
