Calibrating a refractometer

Hi,

Can I use 5% medical saline solution to calibrate a refractometer?

I would think that it ought to read 50ppt, but I am not sure it is that simple.

Thanks,

Flobajob.

No, saline solutions (Sodium Chloride in water) have a different refraction index than salt water. This article can help.
