Changing Reducing Agents in an Assay

[Audacity Con]

I am in need of help answering a question. I am an environmental geologist faced with the need to comment on techniques for gold assaying. Such questions are best left to mineralogists. My question: can changing the type of reducing agent in a gold assay test from flour to argol make a difference in the resulting fusion and final analysis for gold?

Disclaimer: I know nothing about assaying gold in particular. What I do know, is that small changes to any analytical recipe can have unexpected side effects, so you would need at least some preliminary tests done on a known samples to check if the results from both methods are comparable.
