Hilase is specialised in developing, prototyping and producing instruments for measuring the concentration of gases or aerosols in various applications in accordance to the requirements of its costumers. Hilase already successfully completed commercialising an instrument family (Hilase-Ex) for the natural gas industry for measuring water vapour, hydrogen-sulphide and carbon-dioxide. The company also offers its measurement service in selected applications including
- gas permeability measurement of polymers,
- atmospheric water vapour and total water measuring instrument operable on research aircrafts,
- mobile environmental monitoring station for atmospheric aerosols measurements.
The operational principle of the Hilase instruments is laser based photoacoustic spectroscopy. The unique advantages of the method are its exceptionally wide measurement range, fast response, simplicity, robustness and its long term fully automatic and trouble-free operation. Hilase was founded in 2004. It is a spin-off company of the Department of Optics and Quantum Electronics, University of Szeged, Hungary. Photoacoustic gas detection is an active research field at the Department for more than two decades. Most of the employees of the company are experts in photoacoustics with either having a PhD or a diploma thesis based on photoacoustic R&D work. Hilase is a member of the Videoton group. Videoton Holding Plc. is the 23rd most considerable EMS (Electronic Manufacturing Services) company in the world.
Hilase works in close cooperation with the University of Szeged and the Videoton Holding Zrt. The University of Szeged ensures the scientific background of the activities of Hilase, while Videoton Holding Zrt provides the engineering support for the company. Furthermore Videoton Holding Plc. has a production facility capable to produce photoacoustic instruments on a large scale in case it is required.
Currently Hilase participates in the project: “Improving the measurement accuracy of diode laser based photoacoustic hydrogen-sulphide concentration measuring instruments” (project identifier: GOP-1.1.1-09/1-2010-0075) co-financed by the European Union and the Hungarian Government.
From 2007 to 2010 Hilase was the consortium leader of the JEDLIK_AEROS 'Development of instruments and methods, which contribute to the fulfilment of latest EU regulations for aerosol pollution in ambient air' project by the National Office for Research and technology.
From 2007 to 2009 Hilase participated in the project: 'Development of novel type of photoacoustic gas detection systems based on the latest scientific result in photoacoustics' within the Kozma László program of the Hungarian Ministry of Education.
Between 2005 and 2006 Hilase Ltd. successfully completed the project: 'Commercialization of photoacoustic gas detection and gas permeability measuring systems' (identification number: GVOP-3.3.1.-2004-04-0027/3.0) within the program: 'Support of the innovative tasks of start-up and spin-off companies' of the Hungarian Ministry of Economy and Transport, co-financed by the European Union.
The Evaluation Phase
The first step in developing the targeted instrument is to evaluate the measurement needed by our costumer, to estimate achievable minimum detectable concentrations, possible spectral interferences etc. It is essential to carefully optimise those components (hardware and software), which provide the necessary self checking and controlling features of the foreseen instrument.
Based on the results of the development phase, a prototype is designed, which includes the necessary amounts of lasers and detection cells, the electronics and the supplementary gas handling components. The instrument is programmed to perform the selected self checking and control algorithms. The prototype is designed in a way to meet EMC standards. The calibration method is elaborated and all the documentations are produced.
All the critical components of a Hilase instrument is thoroughly tested and calibrated based on a strict protocol before assembly. The assembled instruments also go through a detailed testing and calibration procedure.
A typical Hilase customer either interested in one of our already commercialised instruments (e.g. for measuring H2S and/or H2O in natural gas; for airborne measurement of atmospheric humidity on aircrafts or measuring atmospheric aerosols in an the NIR-VIS-UV wavelength range) or has a special measurement need in gas concentration monitoring, and seeks for a supplier, who is specialised in developing a highly reliable measurement method, builds a prototype and finally organises and accomplishes the mass production of the developed instrument.
