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.
Reference standards, surface water - trace metals
Supplier: LGC Standards PROMOCHEM
This reference standard is intended for daily use in conjunction with measurement of elements in surface waters. The water solution contains 45 elements with concentrations traceable to
ultrapure metals or stoichiometrically well-defined substances.

Trace elements in water, NIST-1643F
Supplier: LGC Standards PROMOCHEM
This reference standards are intended to use in the determination of trace elements in fresh water. The solution contains nitric acid at a volume fraction of approximately 2%, equivalent to an amount of substance concentration (molarity) of approximately 0,32 mol/l and also it simulates the elemental composition of fresh water.

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.
