What is particle measurement ? It is the process of detecting the size, concentration and distribution of solid or liquid particles in the air. These measurements play an important role in many industrial sectors, laboratories, health facilities and environmental studies. Particle measurement helps to identify hidden hazards in the air and ensure a healthy working or living environment. In this article, detailed information about how particle measurement is performed and commonly used measurement methods will be included.
Particulate measurement is important for determining and controlling particulate pollution in the air. Particulate pollution can be caused by industrial activities, traffic, construction work, combustion processes and other sources. These particles can be harmful to human health and enter the body through respiration. In addition, it can also have environmental effects and negatively affect air quality.
Particle measurement is widely applied in the following fields
Industrial and Environmental Control: It is used for monitoring and controlling particle emission in industrial enterprises. These measurements are carried out as part of emission control, filter efficiency assessment and air quality monitoring programs.
Occupational Health and Safety: It is used to evaluate the particle exposure of employees in workplaces. Particle measurements are carried out to check compliance with the limits of inhalable particles, to assess the effectiveness of respiratory protective equipment and to ensure workplace hygiene.
Health Sector: Particle measurement is performed in hospital environments, clean rooms and pharmaceutical laboratories to evaluate the effectiveness of sterilization, the performance of air filtration systems and hygiene conditions Jul.
There are various methods and devices for particle measurement. Here are some of the commonly used particle measurement methods:
Laser Coagulation Method (LPC): In this method, the size and concentration of particles are determined using a laser beam. The laser beam triggers the coagulation of the particles, and the number and size of the coagulating particles are measured. This method is usually used for the measurement of liquid particles.
Optical Particle Counting (OPC): In this method, the number and size of particles are measured using optical sensors. The light scattering or light absorption that occurs during the particle transition is used to determine the particle size. OPC is a widely used method for measuring solid and liquid particles in the air.
Collection of Air Samples and Laboratory Analysis: The particle sample is collected with an air sampling device and analyzed in a laboratory environment. These analyses use various techniques to determine factors such as particle size, chemical composition and concentration. For example, particle properties can be determined by electron microscopy and chemical analysis.
The particle measurement process generally includes the following steps:
Priority Target Determination: The purpose and target of particle measurement are determined. For example, monitoring the release of particles in a specific industrial enterprise or assessing the level of cleanliness in a laboratory environment.
Method Selection: The appropriate particle measurement method is selected. The method is determined depending on the measurement target, the type of sample and other factors.
Device Selection and Calibration: The particle measuring device is selected and calibrated. It is important to perform periodic calibration in order for the device to work correctly and produce reliable results.
Sampling and Measurement: The particle sample is collected using an appropriate sampling method and measurement is performed with a particle measuring device. The sampling time and density are determined depending on the measurement target.
Data Analysis and Reporting: Measurement results are analyzed and reported. Particle concentration, size distribution and other parameters are evaluated according to the determined standards and limits. The reports are submitted to the relevant parties and used to take the necessary measures.
Result
Particle measurement is an important tool for determining the particle pollution in the air and ensuring a healthy working or living environment. Commonly used particle measurement methods include methods such as laser coagulation, optical particle counting, air sample collection, and laboratory analysis. The particle measurement process includes various steps from priority target determination to method selection, sampling and measurement. Choosing the right method, device calibration and data analysis are important to obtain accurate and reliable results. Particle measurement contributes to the protection of a healthy environment by being used in many areas from industrial sectors to health facilities.
