Spectra from an LPG sensor exposed to toluene concentrations

The transmission spectra of an LPG of period 97um, fabricated in Fibercore PS750, coated by LB deposition of 56 layers of calix[4]res C11.

Each spectra is a single scan of the sensor while immersed in water containig a range of cencentrations of toluene (0-400ppm).
