Due to the up-rise of silicosis, countries like the US, Australia, New Zealand and across Europe are halving the permissible occupational exposure limits to respirable silica to as low as 0.05mg/m3. This new regulation puts pressure on traditional test methods like direct-on-filter FTIR which are not able to reach such low limits of detection.

In this webinar, our applications specialist, Dr Olga Narygina, explains the new dust laws and how service laboratories can adhere to the current norms and prescribed methods. She introduces methodologies like X-ray diffraction (XRD) which is capable of not only low limits of detection, but also accurate quantification. For instance, unlike FTIR, XRD is able to distinguish various silica polymorphs. Learn also from Dr Narygina on how to adhere to not only the local regulations but also international ISO accreditation for your laboratory testing on respirable silica. See how easy it is to perform your own XRD analysis on Malvern Panalytical's high performing, compact X-ray diffractometer, Aeris.

Dr Olga Narygina, Application Specialist for X-ray diffraction

Dr Narygina studied physics at the Ural State University (Russia). After completing her master thesis on high-pressure, high-temperature studies of carbon nanotubes Dr Narygina moved to Bayerisches Geoinstitut (University of Bayreuth, Germany) to obtain her PhD degree. Her work there focused on high-pressure, high-temperature research of iron-containing silicates and alloys. This was followed by a post-doc position at the University of Edinburgh (The United Kingdom) where Dr Narygina carried on with the material property research at extreme pressure-temperature conditions with the focus on the structural properties of alkali metals. In 2011 Olga joined Malvern Panalytical. She started as an application specialist XRD in our Supply Center, Almelo, the Netherlands. A few years later, she progressed into an XRD product managerial role. Recently Dr Narygina moved to Australia and joined the regional applications team. Got a question for Dr Narygina? Email
