Air-O-Cell Sampling Guide
Zefon's Air-O-Cell is a linear spore trap with an impaction trace and is used for the collection of airborne bio-aerosols including fungi, pollen, and particulate.Spore traps are appropriate for air sampling at the beginning of an investigation to set a baseline and as a final check for clearance sampling. They can also be used for monitoring during the remediation process.
The Air-O-Cell cassette is attached to a Zefon Biopump Plus which is capable of drawing 15 litres per minute.The cassette is sent to Eurofins, where it is disassembled and the slide is stained and examined microscopically by a qualified analyst.
Sampling times depend upon the environment being sampled. The table below has suggested times for various environmental conditions.
| Suggested Sampling Times | ||
| Environment | Flow Rate | Duration |
| Outside | 15 LPM | 5 - 10 Minutes |
| Clean Room | 15 LPM | 10 Minutes |
| Indoor - Occupied | 15 LPM | 5 Minutes |
| Basement or Dusty Room | 15 LPM | 3-5 Minutes |
| Wall Cavity | 15 LPM | 1 Minute |
Procedure
- Check the expiry date of the Air-O-Cell is current and remove the seal from the bottom of the cassette and retain to reseal when sampling is complete.
- Attach the cassette to a calibrated Bio-Pump.
- Remove the seal from the top of the cassette and retain to reseal when sampling is complete.
- Set the desired run time for sampling.
- Press "start" and record the sampling time on the Chain of Custody form. The Bio-Pump will turn itself off.
- Disconnect Air-O-Cell from the Bio-Pump and reseal cassette
- Record sample information on cassette and Chain of Custody
- Store cassette in a cool, dry area (<40oC).
There is no maximum time for the analysis to be completed but it is advised to have the count & identification determined within the shortest possible time.
