Particle size analyzer is widely used in industries such as pharmaceuticals, power, petroleum, electronics, etc. It is used to detect the size and quantity of particles in liquids and is an important tool for evaluating the cleanliness of oil products or the quality of drug solutions. Although the instrument has a high level of technical content, as long as the correct operating procedures and skills are mastered, efficient and accurate detection can also be achieved.
1、 Preparation before startup: Ensure that the sample and equipment are in good condition
Before using the instrument, check if the environment meets the requirements: stable temperature, dust-free, and avoid vibration. Simultaneously confirm that the sample has been thoroughly mixed and processed through appropriate filtration or dilution to prevent large particles from clogging the sensor. In addition, it is necessary to check whether the injection tube and discharge tube are firmly connected and free of residual bubbles.
2、 Correctly calibrating instruments: the key to ensuring measurement accuracy
Particle size analyzerBelonging to precision instruments, it is recommended to perform system calibration before each use. Usually, standard particle suspensions are used for calibration to verify the instrument's ability to identify specific particle sizes. Some devices support automatic calibration function, but regular manual verification is still required to ensure data reliability.
3、 Standardize injection procedures: reduce sources of error
After pouring the processed sample into the dedicated injection cup, start the instrument to start measuring. Pay attention to controlling the sample flow rate to avoid bubbles entering the detection chamber due to excessive speed, which may affect counting accuracy. If the viscosity of the sample is too high, it can be heated or diluted appropriately, but relevant parameters need to be recorded for easy conversion of results.
4、 Reasonably set parameters: match different detection requirements
Modern particle size analyzers are often equipped with touch interfaces, allowing users to select appropriate detection standards (such as ISO 4406, SAE AS4059, etc.) based on sample types, and set parameters such as particle size thresholds and sampling times. Reasonable configuration helps improve analysis efficiency and avoid misjudgment.
5、 Timely cleaning and maintenance: effective measures to extend equipment lifespan
After the test is completed, the injection system and detection chamber must be cleaned with deionized water or solvent to prevent residue from drying up and blocking the pipeline. Regularly check if the optical path system is clean, and if necessary, gently wipe it with a dust-free cloth. When not in use for a long time, the power should be turned off and dust protection should be taken.
6、 Recording data and abnormal feedback: improving detection and management capabilities
After each inspection, it is recommended to save the original data and print a report for later traceability. In case of instrument alarm or abnormal data, the cause should be promptly investigated, such as sensor contamination, pump failure, etc. Do not forcefully run continuously.
In short,Particle size analyzerAlthough the operation involves multiple technical links, as long as it is executed according to standard procedures, pays attention to detail control, and continuously optimizes the operation methods based on practical experience, the goal of "easy to learn and accurate detection" can be achieved, providing strong support for product quality control.
