Try this assay. It might work.

Thank you , but this is the only one? Or maybe can use another assay which reagents don't include hydroxylamine hydrocloride?

I doubt it. Hydroxylamine Hydrochloride is a pretty innocuous powder and used for reduction. I haven't found any other titration method (depends on sample matrix interferences), which will leave you with HPLC.
