Diffusive interfacial transport-refractive

In the diffusive interfacial transport-refractive index (DIT-NDX) method, compositions are determined using precise refractive index data (8). Refractive index data valid to +/- 0.00005 are obtainable using the DIT apparatus vithin an area of 30 ym2 in a sample approximately 25-ym thick (0.75 picoliter volume). Data collection and analysis require 9 seconds. The accuracy, spatial resolution, and speed vith vhich refractive indices can be determined are thus superb.
