Is this acceptable 16.7 LPM flow rate for PM-10 in Ambient Air Quality?
- Manufactures of ENVIROTECH, APM- 550 model for Fine particulate sampler can also used for the PM- 10 particles by removing the wince impactor attachment , which has the constant flow rate of 16.7 LPM(1M3/min)
- Whereas, as per MOEF/CPCB guide lines, for PM-10 particulate matter there should be flow rate of not less than 1.1M3/min. with Respirable Dust Sampler.
By above two reasons, Please clarify how can we use APM-550 (envirotech) model, use for PM- 10 particulate?
