Answer / spln

I agree with Dr.SP. Goswami. 10% mobile phase ratio can be
changed, same thing you justify in AMV- ruggedness
parameter.After justification only you revise your MOA as
per your change.

Answer / abdulkalim

± 10% is acceptable , but your internal Guidline/SOP should

Answer / arjun singh

1 )As per USP guideline the MP can be changed +- 10%, but
to get better accuracy it should not across the +- 5 % and
the same change should be written in SOP with justification
by giving all data accuired in case of changes. it should
be included in in house specification and same can be used
in routine practice

Answer / vinod kumar, nektar therapeuti

As per me ±2% change in initial mobile phase composition is
fine to check the ruggedness of the method.
