ISO17025
atomic absorption spectroscopy application
AAS for pharmaceutical and chemical
Atomic Absorption Spectroscopy (AAS) is a versatile trace analysis method that is frequently used in quality control and quality assurance due to its high performance. This single-element quantification can be used to determine heavy metals, toxic elements or similar.
