Brochure : Guide to Moisture Analysis
Moisture affects the processibility, shelf life, usability and quality of many products such as pharmaceutical substances, plastics and foods. Information about and monitoring of moisture content is therefore very important. Most substances have an optimum moisture content for obtaining the best possible processing results and therefore attaining maximum quality. Furthermore, moisture content impacts on price and there are statutory rules for some products governing the maximum permissible moisture content (e.g. as defined by national food regulations).

White Paper: Drying Oven vs. Halogen Moisture Analyzer
A Practical Guide to Compare Methods
Moisture content is a key quality parameter in most industries, including food, chemical, and pharmaceutical industries. Moisture content determines the quality and the cost of raw materials; it affects product quality (e.g. shelf life) and often influences the financial margin of finished goods. Moisture is also a key parameter for process control in many production processes. For these reasons, monitoring of moisture content is very important. These moisture determinations need to be carried out rapidly and reliably so that any interventions in the production process can be made promptly, to avoid costly interruptions.

1. What is a moisture analyzer?
A moisture analyzer determines the moisture content of a sample with the loss on drying method and consists of a weighing and heating unit (infrared). It is often also called moisture balance or moisture meter.

2. How does a moisture analyzer work?
The Moisture Analyzer works according to the thermo-gravimetric principle, also often referred to as the 'Loss on Drying' (LOD) principle. The moisture analyzer consists of two components, a balance unit and a heating unit. In order to measure the moisture content the sample's start weight is recorded, afterwards a halogen lamp or other infrared radiator heats and dries the sample while the integrated balance continually records the sample weight. When the sample no longer loses weight the instrument shuts off and the moisture content is calculated. The total loss in weight is used to calculate the moisture content.

Finding the right moisture analyzer for your application is not always easy. The best moisture analyzer is the one that fits to your specific requirements. Typically, requirements not only concern measurement performance but also other factors such as ease-of-use, data management capabilities, robustness (long instrument lifetime) and compliance features. METTLER TOLEDO offers a wide range of reliable instruments that cover basic, all-round and high-performance requirements.
4. What is the heating system of a moisture analyzer?
The heating source (halogen lamp, metal rod, ceramic, quartz lamp) and its regulation are defined as a heating system. All mentioned heating sources are infrared radiators. This means the sample is heated by absorption of infrared radiation.

5. What are the advantages of halogen heating?
The most important performance factor is precise and fast temperature regulation, which is best delivered by halogen lamps because of their low mass and therefore fast reaction time. This ensures repeatable results starting from the first measurement (while some other heating sources either deliver different results in the first measurement or require a warm up measurement which is wasting time and resources). Furthermore, an even heat distribution on the sample surface is essential for repeatable and reliable results. We advise to ask the manufacturer for a demonstration and experience the performance in real-life.
6. What is the best moisture analyzer for laboratory or production workers?
Typically, laboratory and production workers require an instrument which is intuitive to use and guides operators through the process. This ensures that users are following the right procedures thus preventing handling errors. Graphical user guidance, method shortcuts, user management and many languages are helpful instrument functionalities.

7. Which moisture analyzer is recommended for best repeatability?
The HX204 moisture analyzer is recommended. A high-performance weighing cell with 0.001% moisture content readability separated from the heating source ensures best moisture results even when measuring very low moisture contents.

8. How does the moisture analyzer support me in being compliant to regulations such as USP, FDA, ASTM or 21 CFR Part 11?
Basically, two topics are important with regards to compliance: data management and performance testing. Ensuring data integrity means that every result record needs to be attributable (who has done the measurement), legible (traceable, readable), contemporaneous (recorded at time of generation), original and accurate (correct, complete). Please keep in mind that an instrument is never compliant by itself but it can support the user in being compliant. The HX204 is the moisture analyzer for industries with the highest demands in compliance. It supports the user with safety and data integrity functions such as user management (prevention of changes & unique user log-ons), tailor-made reporting (including non-modifiable PDF reports) and with integrated performance testing of all relevant measuring systems (heating unit, balance, overall instrument test) at point of use.
