A Moisture Analyzer performs moisture analysis by using the ‘loss on drying’ (LOD) method. To read more about how a moisture analyzer works click here

Generally, results are achieved rapidly when using a moisture analyzer, often in a matter of minutes, and with better repeatability. In contrast, performing loss on drying using an oven can take a few hours and involves a more complicated procedure.

As long as a method is developed which is comparable to the method which would be utilized for the traditional drying oven methods, then results will be comparable. See the example below:

Analysis of a store-bought dog chew was performed using the Precisa XM60 Moisture Analyzer and, for comparison, a drying oven. The sample (2 g ± 10%) was spread evenly over the sample pan. The XM60 performed the analysis in under 10 minutes resulting in a moisture content of 12.13% ± 0.06%. By comparison, the drying oven method took 2 hours and calculated a moisture content of 12.26% ± 0.11% (3 measurements).

The best way to ensure reliable results from your moisture analyzer is to develop the best method possible. Drying methods will vary depending on the properties of the sample under test. The most effective drying methods include appropriate sample preparation, drying temperature, drying program, and stop-criteria.

Yes – as long as the results from each method are comparable within certain limits (accuracy and repeatability) as defined by the context of the application click here

The sample should ideally be homogenized, or cut into slices as thin as possible, see some examples of how food samples are prepared for analysis here

The range is 5% – 95% moisture.

Yes – but a glass fibre filter is recommended for fatty samples or sample that contain a high moisture content as it is able to increase the surface area of the sample, to assist in complete and rapid moisture loss.

The glass fibre filter should be placed in the aluminium pan prior to sample being added.

Halogen moisture analyzers: the fastest heating option with easy control, contains a glass tube filled with halogen gas and a tungsten heating element.

Infrared moisture analyzers: fast and precise measurements of moisture content which is durable and energy efficient. It is the ideal choice for dark coloured samples as radiation is absorbed by the sample

Thermogravimetric analysis (TGA) is a type of thermal analysis where the mass of a sample is measured as the temperature changes over time. To find out more about TGA click here

The conventional method of thermogravimetric analysis involves multiple sample weighings and transfer steps which requires various different pieces of equipment such as ovens, muffle furnaces, and desiccators. This process can be tedious, time consuming and prone to user error. The PrepASH thermogravimetric analyzer offers the automatic analysis of moisture, ash, and loss of ignition in one run saving the user time and effort.

Other benefits of the PrepASH include:

• Analysis of up to 29 samples simultaneously
• Creating and storing of unlimited methods / standard operating procedures, ensuring consistency and traceability of results
• A selectable combustion atmosphere and a scrubber for sulfated ash applications
• Operation of an autonomous device without the requirement of an additional PC.

To find out more about the benefits of the PrepASH click here

The PrepASH is the ideal instrument for industries which require accurate and efficient determination of moisture, ash, and loss on ignition. Examples of these industries includes:

• Food and drink
• Pharmaceutical and cosmetics
• Environmental and agriculture
• Mining and metallurgy
• Chemical and petrochemical
• Polymers

The Precisa operates from 50^oC to 1000^oC. To find out more about the PrepASH click here

As there is a balance within the PrepASH, it requires calibration which can be performed quickly and efficiently. Please watch the video to find out how to calibrate your prepASH

In order to maintain accuracy, a suggested weight of 4g is recommended as a minimum. The maximum weight depends on the type of crucible used, the balance capacity is 120g

We have a wide range of crucibles available to suit a wide variety of needs. To learn more about the crucibles offered click here

Yes – the 12 sample disk with the adaptors can be used for platinum crucibles.

Loss on ignition (LOI) measures the organic matter content in samples and involves heating a sample at a desired temperature which enables volatile substances within the sample material to escape until the mass of the sample ceases to change.

It takes between 10 and 11 minutes for the 29 sample holder plate to fully rotate. The time taken for the 12 and 19 sample plate to rotate will be lower.

This depends on the type of sample being analyzed, the temperature settings and the length of time of analysis.

Yes – with the addition of a scrubber sulfated ash applications can be completed safely and efficiently. To find out more click here

Semi micro balances with a readability of 0.00001g, analytical balances with a readability of 0.0001g, and precision balances with a readability of 0.001g to 1g.

There is no set time as to when your balance needs replaced, however you can look out for the signs that your balance may need replacing, which includes inability to hold calibration, balance requiring constant maintenance, and corrosion. To find out more click here

The general rule is to clean your balance at least once a week, however this may need to be increased depending on the application. To see step by step instructions on cleaning your Precisa balance please click here click here

This depends on user requirements, but the general guidelines would be at least once a year, to read more about balance and scale calibration click here
