Is this Titania powder? film? solution? In either case the pathlength must be adjusted so that the minimum transmittance is larger than 10-5%, meaning absorbance is lower than 1-1.3 in the region of interest.

It is best to measure the reflectance of the sample. For this purpose, it is best to use barium sulfate as a matrix and prepare the sample in it. Then just measure the reflectance spectrum and from this you can know the absorption spectrum.
