Is this acceptable 16.7 LPM flow rate for PM-10 in Ambient Air Quality?

 

1. 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)

 

1. 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?
