smps measurements
In recent decades, with the introduction of new technologies, materials and processes of working with nanomaterials, we have increasingly began to aware that they can also be potentially dangerous to health. Although there are currently regulations for allowed levels of particulate matter in the air for larger micron size particles, these guidelines are not sufficient to define the state in the area of nanoparticles. Nanoparticles have significant effect on human well-being, health and the environment in which it is located. We study them in different areas divided by their properties. In terms of toxicity, they are likely to represent a significant impact on human health, in terms of meteorology we find a direct impact on the weather, from a scientific point of view by studying on their other properties, we can see that precisely because of their size, physical and chemical properties are not necessarily identical to those, which are typical for the larger particles. All the above effects are the reason for developing devices that are able to detect a single nanoparticle. We're talking about detection in the aerosol. Nanoparticles can not be evaluated by standard methods of weighing, as they have very little mass. It was necessary to develop a different method - counting. Classical meters take into account the electrical mobility of (nano)particles and count them on optical principle, where the laser beam perceive previously liquid coated particle.
