Dear Ratih Dewi Sujana , of course you can. Polarimetry allows you to know the sugar concentration of a sample through this formula: [ α ]T λ = α /l c

Where:

[ α ]T λ = specific rotation, a constant for any substance, but it depens on T=temperature and λ=Wavelength of the light used for the measurement. For Glucose at 20ºC and using the sodium D line at 589,3 nm the value of [ α ]20 D = +66,5 º.

α= is the angle of rotation of your sample (under the same conditions of temp and wavelength, 20ºC and D line)

l= is the length of your sample cell in dm (often the cell is 10 or 20 cm long, so 1 or 2dm)

c= is the concentration of your sample, the value you want to know.

Hope it helps.

Dear Manuel Gómez

Thank you so much for your explaination.That helped me a lot.

You are wellcome!
