NO3-N, NH4-N and HPO4-P


Some lab reports show the NH4, NO3 and PO4 data as the weight of the main element. Our APP is capable of showing both options, you can choose to see your data as the weight of the whole ion in PPM or the ion as its main component. 

For example:

100 ppm NH4 as NH4-N would be 78ppm

100 ppm NO3 as NO3-N would be 22.6ppm

100ppm HPO4 as HPO4-P would be 32ppm

Data in mmol/l is the same as it is given as the number of molecules not weight
