FSSS Meaning

What is Fisher Sub Sieve Sizer (FSSS)?

The Fisher Sub Sieve Sizer (FSSS) is a laboratory instrument used to determine the size distribution of particles in a sample. It works by vibrating a sample of the material on a sieve with a set of standardized screens of different mesh sizes. The particle size distribution is then determined by measuring the amount of material that passes through each screen.

The FSSS is commonly used in industries such as pharmaceuticals, cosmetics, and food processing to measure the size of particles in powders and other materials. It is also used in the construction industry to measure the size of aggregates in concrete.

How does Fisher Sub Sieve Sizer (FSSS) work?

The Fisher Sub Sieve Sizer (FSSS) works by vibrating a sample of the material on a sieve with a set of standardized screens of different mesh sizes. The screens are placed on top of each other, with the smallest mesh size at the bottom and the largest at the top.

The sample is placed on the sieve and the sieve is then vibrated at a specific frequency. The particles in the sample pass through the screens, with the smaller particles passing through the smaller mesh sizes and the larger particles passing through the larger mesh sizes.

As the particles pass through the screens, they are collected in a series of pans or containers. The amount of material collected in each pan is then weighed and the particle size distribution is determined based on the weight of the material collected at each screen size.

Is Fisher Sub Sieve Sizer (FSSS) accurate?

The Fisher Sub Sieve Sizer (FSSS) is generally considered to be a reliable and accurate instrument for determining the size distribution of particles in a sample. However, like any laboratory instrument, the accuracy of the FSSS can be affected by factors such as the quality of the sample, the skill of the operator, and the condition of the instrument.

To ensure the accuracy of the FSSS, it is important to use a representative and homogenous sample of the material, to properly calibrate and maintain the instrument, and to follow the manufacturer's instructions for use. Additionally, the operator should be trained and experienced in using the FSSS to ensure accurate results.

Is Fisher Sub Sieve Sizer (FSSS) expensive to conduct? 

The cost of conducting a Fisher Sub Sieve Sizer (FSSS) test can vary depending on factors such as the size of the sample, the number of screens used, and the complexity of the analysis. In general, however, the FSSS is not considered to be an overly expensive instrument to use.

The FSSS is typically used in a laboratory setting, where the cost of the test can be absorbed by the laboratory or the client. The cost of the FSSS test may also be offset by the value of the information it provides, such as the particle size distribution of a material or the quality of a product.

How long does Fisher Sub Sieve Sizer (FSSS) take?

The time required to conduct a Fisher Sub Sieve Sizer (FSSS) test can vary depending on factors such as the size of the sample, the number of screens used, and the complexity of the analysis. In general, however, the FSSS is a relatively fast instrument and can provide results in a relatively short period of time.

For a small sample and a simple analysis, the FSSS test can be completed in just a few minutes. For larger samples or more complex analyses, the test may take longer, but it is still typically faster than other methods of particle size analysis. The exact time required for a FSSS test will depend on the specific conditions and requirements of the analysis.
