About Cobalt Standard for AAS

Cobalt Standard for AAS is a precisely calibrated liquid solution designed for use as a calibration standard in atomic absorption spectroscopy (AAS). This odorless, clear colorless to light pink solution is fully soluble in water and prepared using cobalt nitrate or other cobalt salts, deionized water, and potential stabilizers. Stored at room temperature in a tightly sealed container away from direct sunlight and heat sources, it has a typical shelf life of 1224 months under proper storage conditions. It features a density of 1.2 g/cm and a pH level between 57, tailored for analytical precision in quantitative analysis of cobalt in sample matrices. With analytical-grade purity and concentrations such as 1000 ppm cobalt, this standard is ideal for accurate laboratory applications. This solution is non-poisonous and meets EINECS No. 231-158-0 and CAS No. 7440-48-4 standards, as well as HS Code 28421000 requirements.
