Particle Counting and Size Distribution

Some synthetic particles are directly toxic to microorganisms, plants, and animals, while others may pose a secondary risk. Although the concentration of particulate matter in the environment is not too high, their effect on human health is unknown.

Particle count and particle size distribution analysis can help determine the composition of natural water, treatment plant intake, process water, and finished water. Again, it can help design processing processes, make decisions about operational changes, and determine process efficiency. Depending on the sample material and detection range, BOC Sciences has a variety of technologies that can be used for particle detection in water, including dynamic light scattering, ICP-MS and optical microscopy technology.

Testing Services

BOC Sciences' water quality testing laboratory performs testing for a variety of industries and organizations. In addition to particle analysis in water and wastewater, we offer a full range of water quality testing services, including routine physicochemical analysis, microbiological analysis, organic testing, metals testing, contaminant analysis, radioactivity testing, and bromate testing.

Particle analysis in water

BOC Sciences usually uses ICP-MS to characterize particles, which can be detected not only for particle size, particle size distribution, element composition, and quantity concentration. After these data are examined, water quality can be assessed.

Data analysis

Our water quality experts will analyze the test data and compare it with the corresponding laws and regulations to determine whether the water quality meets the requirements. If the product does not meet the requirements, you can consult us, our experts will give you customized solutions for your product, so as to help you efficiently complete the development of the project.

Testing Technology

Different particle detection laboratories choose different particle size distribution analysis methods. In addition, the type of material used for testing also determines the methods that can be used.

ICP-MS Technology

ICP-MS is unique in its ability to provide information on particle size distribution, element composition, and quantitative concentration in one rapid analysis.

Dynamic Light Scattering (DLS) Technology

Dynamic Light Scattering Technology is used to analyze the light intensity fluctuation of scattered light and then calculate the particle size. It works on the nanoscale.

Optical Microscopy Technology

This is direct counting and size measurement by microscope.

The Importance of the Testing

• The need for particle size distribution and particle count analysis is to be able to fully understand:

• The composition of water in rivers, lakes and groundwater;
• Composition of water entering a treatment plant;
• Components of drinking water after treatment from a treatment plant;
• And the components of wastewater produced during treatment and purification;

These tests are necessary and non-compliance will not allow subsequent operations.

• Monitoring these characteristics also helps to make decisions regarding the proper operation of the water purification system and its appropriate maintenance and maintenance to achieve optimal process efficiency.

Factors Affecting

• Efficiency of continuous flow assays or batch samples
• Detection limits
• Solubility
• Particle size range
• Sample concentration

Once all these factors have been checked, the appropriate process is selected to obtain the best results.
