Design The NIR calibrator and its measuring, operating and evaluating componentsare contained in a water resistant IP54housing. A industrial fiber optic cable connects the probe so that measurements can not only be taken in the integrated analysisarea but also at other locations, in theMA35 or directly in the production process. Thanks to the device’s compact design, it can be quickly transported toother testing locations. Software The LMA500’s software is easy to use andintuitive. All data are protected. Onlyusers who have authenticated can access the system. User permissions can be indi- vidually modified to suit your needs. Noexpert knowledge is necessary to create,extend or adjust calibration settings. Verification made easy Multivariate evaluation offers index values for evaluating measurements. This information identifies anomalies or samples that have been categorized incorrectly so corrective action can betaken immediately. Applications The LMA500 is designed for analyzing the moisture content of pourable and granulated products, and viscous prod-ucts as well such as slurry. It measuresmoisture content within a range ofapproximately 0.1%–50%. Calibration with a direct measurement is required if you wish to use the NIR calibrator. The NIR calibrator is optimized for use withthe MA35 moisture analyzer. Naturally,other reference methods can be used. The major applications of the NIR cali- brator include laboratory analysis andat-line process control. Analysis does notmodify the sample, so the sample can still be used after measurement.

Sartorius LMA500Analyzing moisture content with optics— quick, reliable, non-destructive

Thermogravimetry The LMA500 uses spectroscopy. Itexploits the interaction between light and the sample. If the sample is exposed to near infrared light (NIR), a part of thislight is reflected and modified character-istically on interaction with the sample. This change in the NIR light, which is dependent on the water content of thesample, reveals its moisture content. Calibration The LMA500 calibrates itself by analyzingdata it has collected using sophisticatedmultivariate statistics (regression analy- ses, approximation procedures) practi- cally without the need for user input orexpert knowledge. If desired, you can quickly adjust the calibration by con- necting an MA35 rapid moisture ana- lyzer. This allows you to adjust to changes in sample characteristics, givingyou another method for updating your system to new batches. Or you can create calibrations for products that have justbeen added to your product portfolio.Calibration settings for many classes of substances are available from Sartorius.
