- From (3) weight fraction xJ is a linear function of intensity ratio:
xJ = [xS / (KiJ / KhS ) (1-xS) ] • [IiJ / IhS ]
= constant • [IiJ / IhS ]
- Internal standard method can be used to analyze any phase in a mixture without analyzing remaining phases. If all phases determined, then mass balance will hold.
Precision: Approximately 1% relative error
Detection Limit: Measured in tenths of percent
