Moisture is defined as the loss of
mass seen when a sample is heated and is based, in principle, on the
evaporation of water during the drying process; however, this measurement does
not differentiate weight loss of water from loss of volatile components or
sample breakdown. Moisture analyzers calculate a material's loss-on-drying by
comparing the weight of a sample before and after heating. As a result,
moisture content as measured by thermogravimetric methods encompasses all
compounds that evaporate when a sample is heated and is quantified as weight
loss during the healing process.
Â
Moisture analyzers (or moisture
balances) in the MB Series measure moisture Thermo gravimetrically. When
utilising a thermogravimetric instrument, the phrase "moisture
content" is used instead of "water content."
Â
The Karl Fischer-type analyzer,
which titrates KF reagent containing iodine to sample electro-chemically, is another
technique of detecting moisture content. The Karl Fischer method allows for
measurements ranging from a few ppm to 100% (water), however the operation is
difficult and the device is costly, thus we advocate utilising moisture analysers.

4 Reasons Moisture Analyzers Should Be Trusted
Â
1.    Simple to Use
Â
Moisture analyzers are simple to
use in comparison to other approaches, such as wet chemistry or using an oven
and a balance, which might take hours due to the complexities of the operation.
Because of the intricacy of the water molecule and its strong intermolecular
bonding capabilities, measuring moisture content in particular materials can be
challenging.
Â
2.    Repeatable
Â
Moisture analyzers are
reproducible, but other techniques of determining moisture may result in
mistakes such as moisture recovery after the sample has been heated and
weighed. Because the portable
moisture analyzer is a single
device, it solves this issue.
Â
3.    Time-Efficient
Â
Moisture analyzers measure
moisture content quicker than most other methods. They dry a sample efficiently
by transferring energy via radiation (the transmission of energy in the form of
waves or particles across a medium—in this case, the sample) and convection
(heat transfer by mass motion).
Â
A traditional drying oven, on the
other hand, primarily employs convection to dry a sample. Infrared energy is
emitted by both metal and halogen heating components. The moisture analyzers
are automated devices that combine a heating element operated by a
microprocessor and an analyzer.
Â
The moisture content of a sample
may be determined in minutes rather than hours with such a device.
Â
Versatile moisture analyzers can
accept a wide range of materials and parameters. Moisture analyzers, for
example, include storage and numerous ways for testing materials. A technique
is a collection of parameters that govern how a sample is dried. It comprises a
drying programme, temperature(s), and other parameters that specify how the
results are shown, allowing you to find the optimum technique for drying a
sample to get the desired outcome.
Â
Debunking Some Common Moisture Analyzer Myths
Â
â—Â Â Â Â Â Â
Myth: Moisture
analyzers measure the amount of water in the air.
Â
While some people assume that a
loss-on-drying moisture analyzer analyses the moisture content of a sample, it
really measures the weight change of the sample. Anything that evaporates, such
as oils, fats, and other similar compounds, will be measured by a moisture
analyzer.
Â
Moisture analyzers are neither
exact nor accurate, according to popular belief.
Â
Truth: The
fundamental objective of a moisture analyzer is to be precise—to generate a set
of findings with very little fluctuation when many samples are tested under the
same conditions.
Â
To ensure accuracy, the user must
choose a method and prepare the sample properly. Accuracy and precision are
automatically assured when the samples are prepared the same way and the
circumstances and parameters are the same.
