Dear All,

I have reagents from HACH brand for measuring phosphorus and nitrogen concentration in water. However, the UV spectrophotometer is broken. HACH has methods for measuring P and N concentration. I was wondering if I could use those reagents in another UV spectrophotometer (HITACHI U 2910)? What kind adjustment should I use to get the values.

I have attached the methods from HACH.

Appreciate your time.
