The new LMA200PM moisture analyser from Sartorius Mechatronics sets new standards in speed and accuracy for measuring moisture content in a wide variety of materials
From ketchup to moisturising cream to paint, moisture content is a decisive factor in determining the quality of a finished product.
This is especially true in substances with extremely high moisture content.
Utilising the loss-on-drying technique that heats the sample with microwave radiation and in just 40 to 120 seconds the Sartorius LMA200PM delivers precise results of the moisture content of the substance being tested.
This technique has proved to be the fastest and most effective drying method, particularly for materials that contain a high proportion of water.
At the same time, the LMA200PM's integrated analytical weighing system with a resolution of 0.1mg ensures unbeatable accuracy for determining wet and dry weights of the sample, which form the basis for calculation of loss on drying.
To achieve fast measurement times, the LMA200PM bombards the sample with microwave radiation from two fields located on the floor of the cylindrical sample chamber, directly below the sample.
The microwave radiation, in the 2.45GHz range, is thus focused directly on the sample ensuring homogenous distribution of microwave energy in the sample material, eliminating the hot spots and cold spots that can occur with conventional microwave heating units.
In addition, to prevent contamination, the water vapor emitted during drying in the LMA200PM is rapidly conducted away from the sample leaving it dry and ready for further analysis.
This is accomplished by applying the sample material to a glass fibre pad, which allows the water vapour to escape from both the top and the bottom.
An exhaust system draws the water vapour out of the sample chamber, thus preventing condensation.
User-friendly, automatic operation Simple, efficient and safe as the color touch screen on the LMA200PM provides excellent readability and easy operation of the unit.
Just one button is all that's required in routine operations; all other steps are automatic, and plain-language guidance texts support the operator.
The measurement results are locked into the display until the user presses a key to start the next analysis.
Complete moisture analysis technology form one resource.
From incoming inspection to production monitoring to laboratory QA and research and development, Sartorius Mechatronics has staked its claim to be the top instrument provider for moisture analysis.
Together with the LMA200PM, and their recently introduced high speed microwave resonance technology - an indirect detection method that works in just seconds and is ideal for use on or at the production line - and their well-known moisture analyser series with infrared dryers as well as a coulometer for selective detection of water in the low ppm range, Sartorius Mechatronics now covers all the bases.
