There is no need for a modifier in case of hydride generation. Take care of the ph and the amount of boron hydrate.

I. S. Matveeva

For measurement of As in liquid extracts by GF-AAS method, the modifier palladium nitrate + magnesium nitrate (5:1) must be used. The amount of modifier is approximately 10 µl per 20 - 25 µl of extract.
