Each unit of SRM 1643F consists of a polyethylene bottle containing ~250 ml of acidified water, sealed within an aluminized plastic bag to maintain stability. The SRM simulates the elemental composition of fresh water. The solution contains nitric acid at a volume fraction of ~2%, equivalent to an amount of substance concentration (molarity) of nearly 0,32 mol/L.
