HYDRANALÂ®-Composite 22 is very stable and has a shelf life of three years. The titer decay is approximately 0.1 mg H 2 O/mL per year.HYDRANALÂ®-Composite 13 has a titer of 0.7 to 1.0 mg H 2 O/mL and is used for the titration of samples with very low water levels.t is determined in a working medium of high chloroform content (80% HYDRANAL Â® -Chloroform 3, 20% HYDRANAL Â® -Methanol dry 2, v/v) following procedure 8.2 (L 073). Saccharose (sucrose) must be completely dissolved in order to determine the total, i.e. entrapped as well as adherent water content.
