We identify a demand in research and development, initiate new projects based on tasks, cooperate with different independent professional institutions and facilitate standard and non-standard methods of testing and research, creating a better approach and optimization, helping our customer to reach their goals.
Inorganic particles can be a dust from the exterior ambient air, originated from soils and rocks, also can originated from building materials, like concrete dust, and the dust from different insulation materials, used in construction. Asbestos fibres of different mineral nature is the most concerning components in the ambient interior air. Microscopic methods are used for identification.
Organic components in the dust is very common, and it can be identified many types of textile fibres, which is used in every interior design. Fibres can be natural origin like cotton and hemp or artificial and synthetic, like polyester, polyamide (Nylon), polyolefine (PE, PP). Also organic component can be a part of more complex biological issues, related to fungi and bacteria interior activities.
There are many types of aerosol that can be formed in the ambient air, and some aerosols are very complected. The behaviuor and the physical and chemical properties of aerosol particles is determined by its structure, which can be studied by different methods, including Raman microscopy. The impact of aerosol on ambient air is crucial, and needs to be determined.

Organic component can be a part of more complex biological issues, related to fungi and bacteria interior activities. The spores are airborne with the size of 30 μm, and especially in the size range 2 μm to 10 μm. Filamentous Fungi (Mould) is derived from different taxonomic groups: Ascomycetes, Deuteromycetes and Zygomycetes. Some spores can reach up to 100 μm and less mobile. For example the spores of Aspergillus or Penicillum genera are very small and are definitely of airborne nature. On the other hand spores of genera Stachybotrys, Fusarium are bigger and embedded into slime matrix and less mobile instead. Spores are videly presented in the exterior ambient air as well as in interior environments, so the considerable growth in dampness affect the health impairment of indoor ocupants.
Serpentine and Amphibole groups of minerals are the main source of asbestos fibres with silicate nature, having the crystallized asbestiforms, which are considered to be separated into long, flexible, strong fibres, after the manufacturing process. The most common minerals are chrysotile (12001-29-5), crocidolite (12001-28-4), grunerite asbestos (amosite) (12172-73-5), anthophyllite asbestos (77536-67-5), tremolite asbestos (77536-68-6) and actinolite asbestos (77536-66-4). Asbestos fibre longer than 5 μm, and which has a width between 0,2 μm and 3,0 μm, of aspect ratio greater than or equal to 3:1. For identification of asbestos fibres on air samples the use of Phase Contrast Optical Microscopy (PCM), Scanning Electron Microscopy (SEM) or Transmission Electron Microscopy (TEM) are specified in ISO 16000-7.
Aerosols can be liquid droplets (water) or solid particles (smoke, mineral dust) suspended in the air. Industrial aerosols can be formed by reaction of sulfur dioxide (SO2) and water vapours forming sulfates. Burning coals and oil produce such aerosols. Combustion engines release Nitrogen Oxides (NOx) which form Nitrates aerosols. Combustions create a lot of sod particles.
The acceptance Criteria is another key principle of providing independent and unbiased R&D deliveries through the multi evaluations and consideration of factors which are going above and beyond a standard approach and conventionalities.
