What is the principle of Refractometry
path of light is deviated when it enters a solution, and the degree of deviation (refraction) is proportional to the density of the solution.
Corrections for Refractometer:
Protein =
Glucose =
Protein = -0.003 for every 1 g/dL
Glucose = -0.004 for every 1 g/dL
Is there a correction in temperature for refractometer
No. There is no correction in temperature
Example:
SG = 1.035; contains 1g/dL glucose and 1g/dL protein
1.035 - 0.003 (protein) = 1.032 - 0.004 (glucose) = 1.028 (corrected SG)
