        • Re: Validation

          Please provide more info.  What system?  What are you trying to do?

          The requirements for %recovery and parameters are established by regulating bodies and not instrument manufactures. 

          It depends on the local regulatory agency.  They will also establish how to test the methods.

              I am trying to do validation by using HPLC method for micro nutrient (like Folic acid, B-12 and biotin).


              In pharmaceuticals industry, generally recovery are 98.0 -102% since, it is related to dietary supplement and top of the it is micro nutrient too.

              so how far i can go for percentage recovery.

              can i use 80-150% ?
