Some Common Applications Of A Lab Moisture Analyzer

Maintaining a healthy level of moisture in an enclosed space, whether it's a home or an office, is important to avoid mould formation. So what do you do when your lab requires some extra love and attention? You could grab that humidifier from the basement and set it up in the lab overnight. Instead, how about taking advantage of modern technology and using a laboratory moisture analyzer?

A moisture analyzer works by using principles like psychrometry to determine water vapour pressure for a given sample. It does this by extracting molecular water vapour from the air sample inside the instrument with cool condenser surfaces. The system then measures any condensed water droplets before releasing them into the airstream.

Structure of Lab Moisture Analyzer

A Moisture Analyzer, or as I like to call it, a "moisture analyzer," is a small handheld laboratory device that can measure air moisture in an enclosed space. It usually consists of two main parts: an instrument, which has a condenser attached to its front and a diffusion cell, often made from quartz, which sits inside the instrument.

The diffuser is where condensate is collected for analysis. The front of the instrument contains dials and buttons for controlling temperature and humidity levels during testing. There are also knobs on the backside for data logging.

Applications of Moisture Analyzer

These amazing quality moisture analyzers have many applications across different industries. Here's a list of industrial applications of Lab Moisture Analyzer:

Food And Agriculture

In the food industry, it's crucial to maintain perfect moisture levels to prevent the growth of harmful microorganisms in food products. While a high moisture level promotes the growth of fungus, low levels spoil the taste and consistency of food. The best way to achieve a proper moisture level is to measure the air used to condense and cool processed food. There's a range of lab moisture analyzers for sale for measuring moisture in the food and other products in industrial facilities.

Air Drying/Curing

Industrial drying and curing is a common process used to prepare products like paper and plastic for shipping or distribution. The process involves using hot air that's blown into a warehouse where different layers are stacked on top of one another. Here, each layer contains pieces of paper or plastic which need to be dried through decreasing levels of humidity (from high levels at the beginning to ideal levels at the end).

Agriculture And Soil Science

If it wasn't for humidity levels in the air, we'd all be vegetarians! A proper moisture level in soil, whether it’s the ground or the air, is vital for preserving crops. Excess moisture promotes fungal growth and contamination, while excess dryness destroys plant roots and causes plants to wither. Therefore, humidity measurements are important to ensure that both ground and air are at ideal moisture levels before starting a crop cultivation process or harvesting.

Pharmaceuticals

Much of the manufacturing process for pharmaceutical products occurs inside large industrial factories. Some of these processes include packaging, filling and sealing, which can be affected by high levels of moisture in the air used to cool, condense or otherwise preserve the quality of certain drugs. A humidity analyzer for sale can be used to test relative humidity levels to ensure these high-quality standards are met.

Industrial Production And Repair

Humidity is an important part of manufacturing and assembly processes, especially involving precision-based product preparation methods like injection moulding. For example, if there's too much humidity in the air, the assembly can be affected by the formation of bubbles within the product itself. This is due to an incompatibility between water and the product, which leads to an expansion of the water and subsequent bubble formation. These bubbles can cause components to become unbalanced or snap off entirely.

Physics And Chemistry

In chemistry, a moisture analyzer can determine the amount of water vapour in the air. For example, when sea salt is extracted from an ocean, it contains a large amount of water vapour, while dry lye is stripped from wood or bone, it contains very little. These moisturizers can also test the moisture levels in various gases, vapours and aerosols. For example, the quality of many commercial baked goods depends on the level of moisture present within the ingredients themselves and not solely their storage conditions.
If a product is too dry, it may come out tough or crumbly instead of flaky and tasty, so measuring humidity levels is important for baking perfectionists (or those who like to bake). There are different types of moisture analyzers that are designed to meet specific.

A Simple Guide To Lab Moisture Analysis: Everything You Need to Know About It

Moisture analyzers, also known as moisture meters or moisture balances, measure the moisture content in samples. They can analyze gases, liquids, and solids and are particularly important pieces of equipment when it comes to testing certain types of products such as pharmaceuticals, food, plastics, fuel, and hydrocarbons. In this post, we reveal how moisture analyzers work and best practices for using them.

How Moisture Analyzers Work

The premise behind lab moisture analyzer is quite simple. They work using a Loss On Drying (LOD) or thermo gravimetric method to determine how much moisture is in the sample. Here are the basic steps:

• The moisture analyzer weighs the sample and records the initial weight.
• A heating element radiates infrared heat to dry the sample. (A few different types of heating element may be used in moisture analyzers, including halogen lamp, quartz lamp, metal, or ceramic.)
• The sample is weighed periodically until the weight no longer changes (this means the sample is fully dried).
• The final weight is subtracted from the initial weight to determine the moisture content.

If you need to find out the solid content of a sample, you simply subtract the moisture content from the initial weight.

Note that moisture doesn’t only refer to water. It includes any substance that will evaporate as a result of infrared heating, for example, alcohols and organic solvents.

Best Practices for Using Moisture Analyzers

Here are some tips to help ensure you get accurate results when using a moisture analyzer:

• Position the analyzer correctly. Make sure the unit is placed away from any sources of draft or vibration such as air vents or refrigerators. It should also be in a non-harsh, clean environment. High humidity, extreme temperatures, or excess dust could affect the accuracy of results.
• Take safety precautions. Assess the risk involved in heating your particular sample. Work in a fume hood where necessary and never try to dry explosive or combustible substances.
• Use clean sample pans. Used pans should be disposed of and you should only use clean, intact pans.
• Ensure an even sample spread. You should cover the entire surface area of the pan with a thin, even coating of sample.
• Don't overload the unit. Be sure to note the maximum capacity of the analyzer as overloading it could damage the internal weighing mechanisms.

How to Properly Calibrate Your Moisture Analyzers

Laboratory-scale To ensure that products meet federal and industry regulations, the moisture content is measured using halogen or other infrared heaters. Like any different exact analytical scale or balance, a moisture analyzer must be accurate to function correctly. To ensure the accuracy of moisture analyzers, two independent calibration processes must be completed: one to ensure temperature and another to ensure weight. If you want to know how to calibrate your moisture balance accurately, keep reading!

Why Do Moisture Analyzers Need to Be Calibrated?

Only a few interruptions may substantially impact the overall accuracy of a moisture balance. The gravitational pull in various locations of the globe necessitates that newly acquired analyzers be calibrated on the spot before they can be utilized. When moisture analyzers are being utilized in the lab or at a different location, even if it's only in a new place of work, changes in ambient conditions might impact accuracy. The workspace should be adequately soundproofed and heated or cooled to prevent noise and temperature fluctuations brought on by moving carts over the floor.

It is necessary to calibrate the weighing system

It is necessary to do external calibration on moisture analyzers to be as accurate as possible. These adjustments are made by combining a particular moisture balance test with predetermined adjustment weights like 50 grammes. The operating instructions accompanying the devices provide information on how to calibrate different models of moisture analyzers. The calibration weight is placed on the sample pan once the device has been set to suit the importance of the pan. For example, if the moisture analyzer shows an incorrect number for the real weight, the analyzer will automatically correct itself, and the exercise will be completed without additional input.

Temperature Testing And Determination

Heating systems may be calibrated using temperature calibration kits, which can be purchased separately. However, your moisture analyzer must be cooled down for three hours before any tests can be carried out. Insert the temperature probe as close to the sensor as possible, following the instructions in the instruction manual.

In comparison to the weight calibration technique, the temperature checks are more time consuming and require the use of two independent pounds. A moisture balance can only offer accurate findings if it is calibrated regularly in your laboratory. All laboratory employees must be aware of the calibration procedure and its timeframes.

Automated Moisture Analyzer: Uses and Working Procedure

An automated moisture analyzer is a piece of equipment that analyses the percentage of water in any sample. This is the most robust type of moisture analyzer available, and it can be used for a variety of applications. It can also be used for a diverse range of materials, making it a valuable piece of equipment to have in any lab.

 

How does Lab Moisture Analyzer work?

Moisture analyzers are generally built around the principle of evaporation. A certain amount of water is dripped onto the sample from a vial. The amount of water on the sample will affect its weight of it. This means that as more water drips onto the sample, the weight increases and vice versa.

A controller will measure this weight change, and you can know what percentage of water is present in your sample. These are elemental moisture analyzers suitable for testing smaller amounts of liquid or powdered materials. Advanced Lab Moisture Analyzer can be used for testing liquids automatically without any human interference. This is done by connecting them to many different instruments like flow meters, weighing scales, or even pH meters.

Applications of Moisture Analyzers

These moisture analyzers are used in many different types of industries. For instance, they are commonly used in the pharmaceutical industry.

• In pharmaceutical, it is used to ensure that medicines have the exact level of moisture present recommended by the manufacturer or standards set by regulatory authorities.
• Moisture analyzers can also be used in laboratories to detect impurities and contaminants in materials. This helps them to prevent contamination errors and maintain a high-quality standard.
• Another common application is to check the quality of food and drinks. Here, it is used to ensure that all of the ingredients put into the product remain at a certain percentage of moisture.
• It can also be used in other industries like research or manufacturing, where specific requirements are set for the moisture level.

If you are looking for something that can be used for a wide range of applications, you should look at an automatic moisture analyzer. These are the most accurate variety available at Global Lab Supply, reducing human error and ensuring that you will always get an accurate reading from your sample.
