1. PRACTICAL SKILLS ON THE TOPIC. SAMPLING OF AIR AND WORKPLACE AIR FOR LABORATORY RESEARCH

2. PURPOSE: Air sampling for laboratory tests carried out under the control of working conditions at work sites, as well as in monitoring air quality

3. : EQUIPMENT NEEDED Aspirator with rotameter Absorption devices gas pipette

4. : THE ALGORITHM STEPS A) sampling method of aspiration

5. 1 -Podgotovit absorption solution, pour it into the absorption bottle in series. 2 Connect the absorption device with an aspirator. 3 Place the system in the breathing zone of the working (or at the point under the settlement.) 4 Pull through the absorption solution required volume of air (depending on the nature of the substance and the expected level of air pollution) In one place sequentially selected 5 samples. 5 When sampling air simultaneously to determine the temperature, humidity and air velocity. 6 Check the accompanying document (where and when sampled, the volume of air stretched for which studies sent to the laboratory, sampling of atmospheric vozduha- weather conditions at the time of sampling.) 7 Send the sample to the laboratory.

7. B. A VACUUM SAMPLING METHOD (USING GAS PIPETTES). 1 Fill the gas pipette water. 2 in the test site of a pipette to pour water (instead of water in the pipette gets analyzed air) to close the gas valve pipette (to clamp or clamps). 3 Check the accompanying document and send samples to the laboratory
