Abstract
Using refractive low coherence interferometry (rLCI) technique we determined the concentration of aqueous mixtures of glucose and albumin. The method is based on second-order dispersion derived from spectral phase of time-domain interferogram. A series of 9 mixtures with different concentration ratios in the range of 5mg/ml to 50mg/ml was performed. The results show errors between prepared and measured concentration of a few percent up to 38%.
