Air Quality Monitoring Reference Methods

Air Quality Monitoring to verify compliance with the environmental standards can only be carried out with the high-precision instrumental methods in accordance with reference, or equivalent methods. This also applies to research studies aimed to understand the short-term behavior of air contaminants.


Reference methods and procedures for an instrument to be included in the reference list can be set at national or international level. The most widely adopted reference list of instruments is the one issued and constantly updated by the US Environmental Protection Agency (US-EPA).


It is important to note that: It is not only necessary to choose analyzers that are compliant with the relevant/US-EPA standard but also to operate the analyzer the same way. Simply ensuring an analyzer’s specifications are compliant with the standard is not sufficient. The US-EPA has issued many guidelines about operating air quality monitoring networks that must be strictly adopted.


APAQ Group portfolio includes a wide range of instruments approved by the US-EPA and can fully assist to ensure that the monitoring activity is performed strictly accordingly to these regulations.
