    User Concentration Methods It is possible to enter and store up to 10 User Concentration Methods. Therefor you need 2 to 14 standards of known concentration and one blank (deionised water or reagent blank value). The Standards should be measured with increasing concentrations and from the brightest to the darkest colouration.
