Dear Rajasekhar!

❝ What is the sufficient measure for matrix effect?

See one of my lectures (slides 9-10).

Concerning your other post I would proceed with the second method, because:

As Ohlbe stated previously you will be able to compensate for differences in ionisation (BTW, stable isotopes would do best), and
Protein precipitation is known to be the worst method if matrix effects are concerned (search the forum).

if only they could discover enough facts about a problem,
these facts would somehow arrange themselves
in a compelling and true solution. Theodosius Dobzhansky
