Dear Members,

The MRL definition for analyte reads: Prohexadione (prohexadione (acid) and its salts expressed as prohexadione-calcium)

I google some publications and notice that authors validate LOQ 0.01 mg/kg for free acid form. Is it correct approach ? Shouldn't it be
validate at 0.01 mg/kg for prohexadione calcium which is equivalent to 0.0085 free acid form especially in GLP studies or i misunderstand something.
