Spectra from LPG sensor repeat testing with 100ppm toluene

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 either water or a solution of 100ppm toluene.
