What are the Recommended Field Sampling Procedures for Via Cells?

The Via-Cell sampler is designed to efficiently collect bioaerosol particles while also providing safe transport to the laboratory. The results achieved when using the sampler requires proper use, including pump calibration and handling tech- niques. Therefore familiarization with the Via-Cell Sampler collection procedure is recommended prior to use.

Required Sampling Equipment

* Via-Cell Sampling Cassettes
* Sampling pump capable of pulling 15LPM
* Tubing to attach cassette to pump, if required (1/4” ID or 1/2” ID) * Pump calibration device

 
Handling the Via-Cell Sampler:
The Via-Cell Sampler is sterile and ready-to-use when received. It is very impor- tant not to contaminate the inner-surface of the cassette through careless han- dling, or insertion of anything into the cassette through the inlet or outlet port. While the collection may render the sampler not sterile due to the collected particles, the person doing the collection should not introduce spurious materials into the collection that could alter the outcome.

 
Handling Tips and Considerations
1. Always store Via-Cell cassettes in climate controlled areas with a room temperature between 50 - 80 degrees F.
2. The Via-Cell sampler does not require refrigeration during storage or during shipment to the analysis laboratory.
3. Prolonged exposure to high temperatures (e.g. as that in the trunk of a car or hot warehouse) may alter the performance of the product.
4. Use of the Via-Cell sampler in extreme environmental conditions (i.e. very hot or cold weather) may affect the collection performance.
5. Always ship Via-Cell samples to the laboratory so that the laboratory receives the samples within 24 hours after collection. The laboratory should process the samples within 24 hours of receipt.
