Product catalog summary

Introduction
This document serves as a comprehensive guide for the moisture analyzers MS-70, MX-50, MF-50, and ML-50 by A&D Company, Limited. It covers the basics of moisture measurement, calibration, application, data analysis, and maintenance.

Basics of Measurement

Moisture Content: Defined as the percentage of water in a material, including hygroscopic moisture and humidity. Types of moisture include water of adhesion, absorbed water, and crystal water.
Method of Measurement: Various methods are discussed, with the heating method highlighted for its simplicity and cost-effectiveness.
Accuracy: Accuracy is defined as the repeatability of results under the same conditions, with a standard accuracy of 0.02%.
Samples: Sodium Tartrate Dihydrate is used as a standard due to its stable moisture content.

Calibration

Calibration can be performed for weight and temperature, with specific accessories recommended for accuracy checks. Results can be documented according to GLP, GMP, or ISO standards.

Application and Data Analysis

Data analysis is facilitated by Windows communication software, WinCT-Moisture, which aids in determining heating temperatures and analyzing results.

Maintenance

Regular maintenance includes checking the halogen lamp and cleaning the device to ensure accurate measurements.

Key Considerations

Not all materials are suitable for testing with the heating method, especially those that are explosive, flammable, or form a membrane when heated.
Sample placement and weight are crucial for accurate measurements, particularly for low moisture content samples.

Specifications and Calibration
The analyzers come with a traceability certificate and a certificate of measurement. Temperature calibration is possible for certain models (MS/MX).

Heating Methods
The analyzers use halogen lamps for efficient heating, with the SRA filter ensuring even heating.

Measurement Procedures
Users can observe samples during heating, enhancing safety and data evaluation. The analyzers incorporate a Super Hybrid Sensor (SHS) for high-speed and accurate weighing.

Comparison with Karl Fischer Method
The MX/MF analyzers provide comparable results to the Karl Fischer method with better repeatability and reduced measurement time.

Typical Measurement Results
Tables include measurement results for various commodities, detailing sample weight, measurement mode, pan temperature, process time, mean moisture value, repeatability, and coefficient of variation.

Software Tools

RsFig: Processes data into graphs, supporting overlapping display and data storage in CSV files.
RsTemp: Determines the optimum heating temperature, displaying moisture content and loss in graphs.
WinCT-Moisture: Facilitates data transfer from analyzers to PCs for storage and analysis.

Recommendations

For high heat resistance samples, use the highest possible temperature for quick measurement.
For volatile oils or dark-colored samples, use consistent conditions and consider glass fiber sheets to prevent carbonization.
Visual and olfactory evaluations are crucial alongside software analysis.

Advanced Usage and Data Analysis
Advanced tips focus on the RsTemp feature for analyzing temperature-related data.

Halogen Lamp Information
Halogen lamps have a lifespan of about 5,000 hours and can be replaced following the instruction manual.

Maintenance and Cleaning
Cleaning instructions emphasize using water-based or neutral detergents and avoiding organic solvents to prevent affecting measurement accuracy.
