- Conclusions:
- The relative density of zinc gluconate was determined using pycnometer method at a temperature of 20 °C and following OECD guideline 109 (Density of Liquids and Solids) and EU MEthod A3 .
The average measured absolute density at 20°C temperature was 1.440 g/ml.
The average calculated relative density at 20°C temperature was 1.440.
Reference
The results of Zinc Gluconate density determination are presented in Table below. As the difference between results was less than 0.03 g/ml; hence two trials were enough.
