Is this part is washable ?
Is there any soldering profile for contact time & heat cycle?
Apologies for missing this. Peak reflow is listed as 260C when you check for package information here, so the JEDEC standard J-STD-020 would be a good reference.
Are you planning to do measurements where the IC will be immersed? The datasheet states that "In wet or corrosive environments, an electrically isolated metal or ceramic well should be used to shield the AD22100."
