Standardised solutions of 30 commonly determined metals are listed with compositions, catalogue numbers and prices in a product data sheet published by Fisher Scientific Co. The Fisher certified atomic absorption standards are 1000ppm solutions which have a shelf life of at least 24 months. Each standard is checked against microchemical standards obtained from the National Bureau of Standards and against spectro‐graphically pure metals, using both classic analytical methodology and atomic absorption techniques to define the concentration of each solution.
