Specs for portable air samples 3-20-18
1. Sample collection must be designed so that decontamination is not necessary between samples. For example the device uses a cartridge or similar sample collection assembly that can be changed in 5 minutes or less (i.e. no more that 5 minutes for the entire changeover between samples). The sample must not contact the device hardware directly during any part of operation. Single-use filter elution kit with sample cup and lid.
2. Elution must also be able to be performed where the filter/sample will not come into contact with any hardware that will be re-used (e.g. elution kits are one-use only items).
3. The filter must be modular (e.g. uses a disposable filter cassette assembly) and the filter can be changed in the field.
4. Flow rate of at least 200 liters per minute (LPM)
5. Multi-directional aerosol inlets
6. Free standing with a height adjustable approximately between 24 and 30 inches (e.g. with an attached stand or tripod)
7. Self-contained functioning unit (e.g. does not require accessories such as hoses or vacuum pumps).
8. Must be able to capture particles between the sizes of 0.1µm and 10.0µm
9. Maintains a constant sample rate/airflow rate (i.e. has a built-in mass air flow sensor)
10. Must be dry filter based collection (i.e. the air sample is deposited on a filter).
11. Uses a dry electret filter
12. Filter size between 40 and 70 mm.
13. The sample can be retrieved in a volume of up to 10mls of eluate
14. Total weight ten pounds or less
15. Portable
16. Battery powered (rechargeable battery) and can run up to 12 hours at full flow rate (i.e. 200 LPM minimum)
17. Must be ruggedized to be used in a field environment
18. Have the ability to check for proper operation at time of sample initiation (e.g., presence of filter, proper flowrate) without additional equipment or opening the sampler
19. Ability to open sampler and retrieve filter with one hand, to replace new filter and close unit with other hand (Cross contamination avoidance)
