Arquin has been training in Dingwall after being told he is surplus to requirements by Notts County boss Shaun Derry.
Ross County manager Derek Adams is casting an eye over Arquin as he ponders taking the Frenchman on loan or signing him on a permanent basis.
"He's up here and he's looking at us as well as us looking at him," said Adams.
"We'll see how things move on towards the end of this week into the beginning of next week."
Adams has already signed four new faces this month in the shape of Filip Kiss, Jordan Slew, Evangelos Oikonomou and Michael Tidser.
