The NMAM (analytical methods guide) 7302 standard designed by the National Institute for Occupational Safety and Health (NIOSH) provides a method for analyzing metal and non-metal dust collected in workplace mixed cellulose ester (MCE) filters. The operating range of this method varies from element to element. The method requires simultaneous fundamental analysis using a microwave refutation approach to simplify and speed up the analysis.

The National Institute for Occupational Safety and Health is an organization responsible for conducting research and making recommendations for the prevention of work-related injury and illness.
The NIOSH NMAM 7302 standard is applicable to industrial hygiene air monitoring, both in the workplace and in the general environment. This method incorporates the speed of inductively coupled plasma atomic emission spectroscopy and the simplicity of microwave single-acid decomposition. For all elements studied, this method is suitable for these elements, such as metals, nitrates, and most of their oxides.
The main heavy metals analyzed in the workplace are: aluminum, arsenic, copper, barium, zinc, iron, cadmium, tin, chromium, lead, magnesium, manganese, nickel, selenium, thallium and titanium.
In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests performed in this context, there are heavy metal analysis and determination of heavy metals in the working environment (NIOSH NMAM 7302).
