Key benefits of IR LEDs and Photodiodes for sensing applications

In 1600-5000 nm spectral range there are characteristic absorption bands of such important chemical agents as water H2O, methane CH4, carbon dioxide CO2, carbon monoxide CO, acetone CH3COCH3, ammonium NH3, C2H2, C2H4, C2H6, CH3Cl, OCS, C2HCl3, HCl, HOCl, HBr, H2S, HCN, CHBr3, H2CO, С2H4Cl2, HF, HNO3, NO2, SO2, glucose and many other organic and non-organic substances. Thus, there is a huge range of applications for optical analysis.

We propose our product as a new powerful base for optical absorption analysis. One of the greatest advantages of this method is that virtually any sample in virtually any state may be studied. Liquids, gases, films, powders, surfaces can all be examined with a proper choice of sampling technique. Using LED-PD optopairs for mid-infrared spectral range allows developing portable sensors with high reliability and adequate accuracy that can be successfully applied in different areas for matter analysis purposes.

Range of applications
Control of technological processes:
✔   Paper industry (water in paper control, paper thickness control)
✔   Oil and petroleum industry (detection of water concentration in oil and oil products)
✔   Thickness testing (thickess of plastic, glass bottles)

Medical diagnostics:
✔  Out-breath control (measurement of carbone dioxide, acetone concentration)
✔  Non-invasive control of glucose in blood

Ecological monitoring:
✔  Control of carbone dioxide, carbone oxide, exhaust gases in the atmosphere
✔  Control of methane, propane leakage
✔  Control of hydrocarbons in water

Food industry and agriculture:
✔  Control of water, fiber, protein concentration in grains
✔  Control of fat and protein in milk
✔ Analysis of ethanol in wine
