Laboratories for Air Quality
The gravimetric method analyses done on tracking filters with robotic system and precision mass measuring systems to determine the concentration of airborne particulates take place in special Testing Laboratories for Air Quality.
These fractioned air particles are collected from different Atmospheres as e.g. PM10 and PM2,5 must be carried out in a precision conditioned room and this is fundamental for the proper weighing procedure as requested by norms.
According to the Reference Standard EN 12341:2014, where it's described the exact procedure of gravimetric test analyses and how to measure the airborne particulate suspended in the air.
The laboratories for Air Quality must be constantly controlled at the following parameters:
|Temperature:||(20 ± 1)°C|
|Relative humidity:||(50 ± 5)%|
PM10 and PM2,5 filters must be conditioned for a minimum period of 48 hours and the laboratory room must be conditioned for the whole period of the mass weighing process of the filters.
Branca Idealair is the company specialized in Precision Air Conditioning of Air Quality Laboratories
The Company offers a wide range of solutions for the precision air conditioning assuring a constant flow of air inlet at the lowest speed (< 0,15 m/s) and suitably filtered to avoid the presence of additional particles that can alterate the results of weighing by the precision scales.
As completion to the air conditioning system, Branca Idealair supply special Data Acquisition system with selected and suitable probes with measure accuracy of ± 0,2°K that collects at every second or minute thermo-hygrometric data during the whole period of conditioning and testing; a special function allows the laboratory enduser to enclose a trend graph to analyses reports and QMS/ audit.
