“…Since PM material on quartz fibre filter is a very specific sample in its structure, none of the commonly used RM (e.g. glass or gelatine standards, pressed pellets, spiked filter matrix, ...) is suitable for its calibration (Brown et al, 2013;Miliszkiewicz et al, 2015;Šala et al, 2017). Matrix-matched RM of PM on quartz fibre filter with certified elemental composition is also not yet commercially available.…”

Airborne particles, denoted as particulate matter (PM), are one of major environmental pollutants.Particles smaller than 10 µm (PM10) penetrate into the human lungs during breathing and exert damage by physical and chemical mechanisms. PM mass concentration in the air as well as major toxicants contained are thus regulated by relevant directives all around the world and their continuous monitoring is prescribed. Elemental composition of PM is one of the most often measured air-quality parameters and the standard method for its determination produces huge amounts of toxic chemical waste.Sustainable alternatives are thus sought for, such as laser ablation inductively coupled plasma mass spectroscopy (LA-ICPMS), which allows for the direct analysis of PM collected on a filter without the microwave-assisted extraction step prior to the analysis with ICPMS. In this work we evaluated the performance of 213 nm Nd:YAG laser system (LA213) compared to the more powerful 193 nm excimer laser (LA193) for this application, in order to facilitate the replacement of the standard method (i.e. MW/ICPMS) with a new, waste-free one. We show that LA213 produces good results when operated under optimized instrument conditions, which were in fact very similar to the LA193 system. Sensitivity for some elements was, however, a bit poorer, but this can be overcome with additional fine-tuning, if necessary. Wrapping-up our thorough evaluation we can conclude that the more affordable LA213 is suitable for air-quality monitoring purposes.
