Normal sugar solution. The “normal sugar solution” is defined as 26.0160 g of pure sucrose weighed in vacuo and dissolved in water at 20.00 °C to a final volume of 100.000 mL. This corresponds to 26.000 g weighed in air under normal conditions (1013 mbar, 20 °C, 50 % relative humidity) and dissolved in water to a final volume of 100.000 mL. The “normal sugar solution” is expressed as a mass fraction (wS,Pol) and is the reference value (100 °Z) for polarimetric sucrose content measurement. This reference value is dependent upon the use of a polarimeter tube length of 200 mm for the polarimetric sucrose content determination for the “normal sugar solution”.
