Workflow of the separation of B in plant sample.

Workflow	Procedure	Validation
Decomposition of plant sample	Dry ashing	Recovery test with Ref. Std.
B separation; (Two-step ion-exchange resin chromatography)	Amberlite IRA 743 resin	Recovery test with Ref. Std.
	Mixed ion-exchange resin	Isotope fractionation test with isotopic Ref. Std.
Determination of B isotope	Cs2-graphite technique for TIMS	Isotope fractionation test with isotopic Ref. Std.
