Atmospheric monitoring
Hilase offers its atmospheric humidity measuring instrument, which can be easily implemented on research aircrafts. Depending on the sampling inlet, it can be used to measure water vapour and/or total water. This instrument was already successfully operated e.g. within the CARIBIC project and a flight test within a EUFAR (EU FP6) project.
Hilase is participating "The IAGOS for the GMES Atmospheric Service" (IGAS, EU FP7). The new IGAS collaborative project serves to establish in-service aircraft measurements as a distributed infrastructure for the European Commission’s Earth Observation Programme. IGAS brings together 13 partners in atmospheric research; it is coordinated at the Max Planck Institute for Biogeochemistry. In this project task of Hilase is development of a compact water vapour and total water instrument (Hilase-Hygro) and developing for the instrument various self-checking algorithms, which ensure the reliability of its long term unattended operation. http://www.igas-project.org.
Aerosol monitoring
| Hilase operates a mobile atmospheric aerosol measurement station, built into a special van. The central instrument of the station is a four wavelength photoacoustic instrument (MuWaPas) developed by Hilase, which is capable to measure real time the absolute optical absorption of the sampled aerosols (TSP, PM10 or PM2.5) in an exceptionally wide wavelength range (@1064 nm, @532 nm, @355 nm and at @266 nm). This instrument is supplemented with an Aethalometer and a TEOM. Filter sampling is also available on the station with subsequent mass as well as chemical analysis. The unique advantage of the MuWaPas instrument is its capability to differentiate between aerosols from different sources such as from vehicle exhaust or from biomass burning. In October 2010 the mobile station was operated at the red mudslide nearby Ajka (Hungary). |  |
Permeability measurements
| With our WaSul-Perm instrumentation we offer our service of determining the gas permeability parameters (diffusivity, solubility, permeability and gas transmission rate) of polymer (plastic and rubber) samples sent by our costumers. The uniqueness of our measurements stems from the fact that due to the wide dynamic range of the photoacoustic method we can record the entire permeation process, which makes the determination of the permeation parameters, by using a numerical fitting algorithm, very precise. Measurements can be performed in a wide temperature and pressure range on samples with various shapes (laminar or tubular) and dimensions. Measurable gases include water-vapor (H2O), hydrogen-sulfide (H2S), carbon-dioxide (CO2), methane (CH4), ammonia (NH3), various hydrocarbons and many others; as well as gas mixtures. Samples with extremely low permeability can be measured as well. For further information please download our brochure about WaSul-Perm. |  |
