Near IR spectroscopy of the solutions of a bacteriochlorin derivative as a quantitative method for the quality assurance of liquid products

The measurement of the near IR spectra of strongly diluted and concentrated solutions of bacteriochlorin derivative in liquid products (hydrocarbons, industrial alcohols) indicated the absence of aggregation to show the prospects of its use under the inconstant optical path conditions through containers as an efficient method for checking the authenticity or degree of dilution with enhanced possibilities for simultaneous analyses of traditional quality parameters.
