Hi everybody,

I would like to know how to validate the method to determine the colour of water samples using the instrument LOVIBOND Daylight 2000. The determination is based on comparing the colour of our sample towards the colour of a comercial template under the same kind of ligth on the scale of Hazen Units.

In the determination it is NOT used a regression calibration so I have no idea how to do this.

I hope you can help me. Thanks a lot.
