LCS Laboratory Inc., offers an air sampling kit for the monitoring of inhalable dust. The samples are collected using IOM (Institute of Occupational Medicine, UK) samplers in full compliance with the UK method MDHS 14/4. The sampling procedure is very straightforward and does not require previous experience.
Your kit includes an air sampling pump, clear Tygon tubing with clips, and an IOM sampler.
Attach the tubing to the pump’s inlet, located on the right side if the pump.
Take the IOM sampler and remove black rubber cup. Put the cup aside, as you will need it to close the sampler for return shipment.
Inside the cassette, you can see a white filter. this is where the sample will be collected.
Remove the small rubber cup from the black tube attached to the IOM. Save the cup, as you will need it to close the cassette at the end of sampling.
Connect the IOM sampler to the second end of Tygon tubing. Now, the IOM sampler is connected to the pump
Use a ballpoint pen to turn the pump on
You instrument was calibrated to 2.0 L/min. Floater inside the built in rotameter shows the approximate flow rate in litres per minute. This small rotameter is an indicator only, it may be 1 L/min off.
Secure the IOM sampler on the worker’s collar. It should be a few inches from worker’s face.
Attach the working pump on belt/trousers using the metal clip on the back of the pump. Congratulations you are now collecting a sample. Record the start time, pump number, IOM ID, and worker’s name. Typically, you collect the sample for at least 1-2 hours, but preferably for the full duration of the shift. Check your pump periodically during the day.
When the sampling is complete, DO NOT STOP the pump. Disconnect the IOM sampler. Inspect it for visible damages, and close it with the 2 rubber cups.
While the pump is still running, you can check duration of the run (in minutes) by pressing a blue button, next to the power switch. This is especially helpful if you forgot to write down the start time. Record the end time in your notebook. You can now stop the pump.
Complete a request form for all samples. Pack everything and ship it back to our lab for analysis. We will calibrate the pump once again, analyze your samples and report the results to you by email.
Troubleshooting.
- Pump doesn’t start. Try to switch on and off a few times. If it turns on, then continue sampling. If it doesn’t start replace the pump with a spare one.
- Pump starts and runs without the IOM. Once the IOM is connected, it starts to work really hard and eventually stops. This is caused by a high pressure drop on the IOM sampler. Check that the 2 rubber cups are removed from the IOM. Check that there is no debris in the tygon tubing or in IOM side tube.
- Pump stopped in the middle of the sampling. Check the run time by pushing the blue button. Record the time. This is the duration of sampling in minutes, from the start to the stop time. Once you restart the pump, the time will be erased. The pump stops if the battery charge is exhausted, pump was mechanically damaged or filter was clogged with dust.
