For the chemical trade, measuring and controlling moisture content material is vital to make sure product high quality and environment friendly manufacturing for the reason that quantity of moisture in deliverables can have various results when changing feedstock into merchandise resembling plastics, polymers, pigments, artificial rubber, resins, salts, acids, components, fertilizers, cleaners or cosmetics. Moisture degree can even considerably have an effect on the price of uncooked supplies, finish product and transport.
Nonetheless, when deciding on the very best moisture measurement know-how for chemical processing, you will need to keep away from selecting solely on the preliminary buy value of the instrument.
Weighing the advantages of proudly owning and utilizing a moisture meter and understanding the way it can impression each effectivity and revenue is vital to creating a profitable long-term acquisition.
In comparison with conventional moisture measurement strategies resembling Karl Fischer or Loss On Drying, a complicated know-how using Close to Infrared (NIR) measurement gives vital advantages.
As we speak, NIR moisture meters may also help chemical processors obtain substantial manufacturing labor financial savings and superior product high quality, whereas optimizing uncooked enter buy value, finish product gross sales value and transport price.

The Benefits of NIR Expertise
Understanding the fundamentals of how NIR know-how works, and for which makes use of it’s best suited, will assist chemical plant managers recognize the way it can save them cash and enhance their backside line.
NIR measurement makes use of reflectance and absorbance ideas for calculating the moisture content material of an merchandise. The meter bounces a beam of sunshine off the product and in some circumstances transmits the sunshine by means of the pattern.
The sunshine is filtered to a wavelength or a number of wavelengths that excite the moisture molecules, in accordance with John Bogart, Managing Director of Kett US, a producer of a full vary of moisture and natural composition analyzers.
“The upper the moisture content material, the upper the quantity of sunshine absorbed. The instrument measures the sunshine mirrored again and an algorithm determines the sunshine absorbed by the pattern,” stated Bogart.
He notes that the moisture meters allow very correct measurement of solids, pastes and liquids with out contact or pattern preparation, so there is no such thing as a contamination in handheld and on-line fashions.
Chemical processors can profit from NIR know-how in 3 notable methods:
1. Extra Environment friendly Personnel and Manufacturing
If a chemical processor continues to be utilizing the Karl Fischer (KF) or Loss on Drying (LOD) technique for figuring out moisture, chances are high {that a} appreciable quantity of personnel time is being tied up conducting these exams when they need to be finishing up extra worthwhile actions.
The KF check entails including chemical reagents to the pattern to separate the water from the remaining product. The water eliminated is then in contrast with the preliminary mass or quantity. Since chemical reagents are used, expert personnel should decide the preliminary parameters, affirm that the system is correctly calibrated and maintained and, at occasions, are required to conduct the exams. These exams take time and destroy the pattern.
Disposal of the waste merchandise will be very pricey and time consuming as properly.
The LOD check, which measures the overall materials weight change after drying, usually requires a pattern to be ready and dropped at a lab. The check takes not less than quarter-hour to a number of hours to carry out, which is simply too sluggish when extra instant measurements are crucial. It additionally requires the pattern to be altered or destroyed.
In distinction, NIR know-how allows the person to get the correct measurement outcomes wanted immediately and is easy sufficient for nearly anybody to make use of with minimal coaching. Usually, solely 7-10 samples are wanted for a legitimate calibration and as soon as calibrated the moisture degree in a product is decided instantly.
For instance, with Kett’s KJT130 Handheld Transportable Prompt Moisture Meter, the person merely factors the instrument on the product and the moisture content material is immediately proven on a digital show, with outcomes correct to .01% in a 0-100% measurement vary.
For ease of use, the unit is operated through person pleasant menu instructions that any employee can function. The unit, which is the dimensions of a camcorder, is designed for frequent spot checks wherever crucial, on each stationary and transferring (course of line) merchandise.
Moisture measurement information could also be saved within the instrument, downloaded constantly or manually recorded.
2. Improved High quality Management
High quality will be compromised if chemical processors would not have the right amount of moisture of their product. This can lead to both product loss or lowered shelf life. Simply as necessary, it may additionally lead to sad clients who might forgo future purchases and even share their displeasure on social media.
Luckily, the velocity and accuracy with which chemical processors can acquire outcomes from NIR know-how will allow them to conduct extra exams inside a given time interval. As a result of services can conduct extra exams and at a better frequency, manufacturing managers will obtain tighter management of their product high quality.
“Since no direct contact or pattern alteration is required with NIR moisture meters, particle dimension variation and weird textures aren’t a difficulty. This may be necessary when used with a variety of feedstocks, formulations or finish merchandise in numerous settings,” stated Bogart.
The flexibility of this know-how means the chemical trade can obtain correct moisture measurements when wanted, whether or not on the method line, within the lab or within the discipline. All of this equates to quicker check outcomes and suggestions. The method allows managers to make sure prime quality in any respect ranges of manufacturing.
As a result of the method is non-destructive, samples additionally stay unaltered to allow them to be used for extra exams or, if eliminated for a desktop check, could also be returned into the product stream.
3. Optimized Purchase/Promote Transactions and Transport Value
When moisture degree is an element within the buy value of uncooked inputs or the tip product gross sales value, correct moisture measurement and adjustment may also help to safe the very best deal.
For example, if buying uncooked inputs with excessive moisture content material, negotiating a reduction is perhaps attainable in some circumstances. If promoting a product by weight, moisture content material might be stored inside acceptable limits, however modified to safe the very best value.
Having the wrong quantity of moisture in a product can even cut back revenue by rising the price of transport. With additional moisture within the product the overall cargo can be heavier, leading to larger transport prices. Correctly drying a substance to acceptable limits earlier than it’s transported can considerably cut back transport prices.
Though chemical processors are extra accustomed to conventional moisture measurement strategies like KF and LOD, the supply of superior NIR know-how is presenting a chance to the trade.
By benefiting from the velocity, accuracy, versatility and ease of NIR moisture meters, chemical producers can dramatically enhance manufacturing, high quality and revenue.
Because of this, NIR know-how for moisture measurement is rising in recognition throughout many industries together with chemical, pharmaceutical, meals, pulp/paper and textile.
