Metal dust and its compound samplerOperation process

Preparation work

(1) Check the appearance and internal structure of the sampler to ensure no damage or defects.

(2) Check the power and battery of the sampler to ensure sufficient charge or a fully charged battery.

(3) Prepare the necessary equipment for sampling, such as sample bags, labels, pens, etc.

(4) Understand the environmental conditions of the sampling site, such as temperature, humidity, air pressure, etc., in order to select appropriate sampling methods and equipment.

Install sampler

Install the sampling head of the sampler in an appropriate position, such as the pocket or collar of the work clothes. Ensure that the sampling head is securely fixed and not easily detached. At the same time, connect the power cord of the sampler to a suitable power outlet to ensure stable power supply.

Collect samples

(1) Wear work clothes, masks, gloves and other protective equipment to ensure personal safety.

(2) Turn on the sampler power and start collecting samples. During the collection process, it is important to maintain the stability of the sampling head to avoid sample splashing or loss.

(3) After collecting the sample, pour it into a sample bag and label it with the sample name, collection time, location, and other information.

(4) Put the bag filled with samples into a dedicated sample box for subsequent processing and analysis.

Cleaning and maintenance of the sampler

(1) After using the sampler, turn off the power in a timely manner to avoid being in the on state for a long time.

(2) Regularly clean the sampler by wiping the surface of the sampling head with a soft cloth to remove dust and dirt. If necessary, specialized cleaning agents can be used for cleaning.

(3) Regularly check the battery performance of the sampler. If the battery is found to be low or aging, it should be replaced with a new battery in a timely manner.

(4) Regularly check the connection components of the sampler, such as power cords, sensors, etc., to ensure that they are working properly. If there is any damage or malfunction, it should be repaired or replaced in a timely manner.

Maintenance work

Regularly calibrate the sampler

To ensure the accuracy and reliability of the sampler, it should be calibrated regularly. The calibration method includes: testing with standard substances of known concentration; Use metrology certification agencies for calibration, etc. The calibration cycle is generally six months or one year, depending on the performance and usage of the equipment.

Keep the equipment dry and clean

During use, the equipment should be kept dry and clean. Avoid using equipment in damp and dusty environments to avoid affecting its performance and lifespan. At the same time, it is necessary to regularly clean the surface and internal structure of the equipment to remove dust and dirt. During the cleaning process, the recommendations and requirements of the equipment manufacturer should be followed to avoid using inappropriate cleaning agents and methods.

Properly store equipment accessories and consumables

Accessories and consumables should be properly stored to avoid loss or damage. Fragile parts such as filter cartridges and filter elements should be replaced in a timely manner according to their usage; Consumables such as batteries and chargers should be charged or replaced according to the requirements of the equipment manufacturer. At the same time, it is necessary to establish an equipment file management system that records the purchase, use, maintenance, scrapping, and other information of equipment for traceability and management.
