You searched for: Environmental Analysis Standards

The environmental analysis standards confirm testing instruments remain consistent for pollutant level monitoring. Single or multi-element solutions can be used to compare and check composition determinations of unknown samples. Accurately assessing threats in the atmosphere, water sources, or soil, personnel can modify and improve conditions to reestablish the surroundings required for optimal performance. Identify all external and internal elements which impact overall growth with the environmental analysis standards.

NIST® SRM® Trace Elements in Water

Supplier: Merck

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.
