Liquids analysis companies offering

CRYOPLANE "Liquid Hydrogen Fuelled Aircraft-System Analysis". Coals A large consortium of companies, research institutions and universities of 11 European countries, co-ordinated by Daimler-Chrysler Aerospace Airbus CmbH, in which the Spanish participation was held by CASA and the Polytechnics University of Madrid, run this project. The project objective considered liquid hydrogen as the only known fuel suitable for aviation to be produced from renewable energy sources and offering extremely low pollutant emissions. 

Polymer IR sample cards are available as an inexpensive disposable sample substrate for qualitative analysis of liquids or solutions. These usually consist of a polymer or crystal film held by a cardboard frame that can be mounted for transmission measurement. The most used polymers are PTFE and Polyethylene, due to their relatively flat IR spectra. PTFE has absorption peaks at 1,100-1,300 and 400-750 cm while Polyethylene at 2,800-3,000 and 1,400-1,500 cm . Some companies also offer these cards with crystal films of NaCl, KBr, and KCl.
