Refractometric Determination of Water Content in Royal JellyApidologie, 39 (2008) 225-232
Abstract - A correlation was found between the measured refraction index of royal jelly and its water content as determined by vacuum oven drying.
Twenty-seven different royal jelly samples were analysed for their water content by performing 24 hour vacuum drying at 48 °C, obtaining values that covered almost the entire range reported in literature. The refraction index values for the same samples were measured using a thermostated Abbe refractometer…
The refractometric evaluation of the water content provides sufficient reliability for the routine quality control of royal jelly and is faster and simpler than currently used methods.

nice posting.To messure range, accuracy etc about the liquids and solids like sugar solutions, confectionery product, oil, glues chemicals etc Abbe Refractometer.
