Definition of Metal Elements
Elemental analysis refers to the use of different analytical methods based on the characteristics of samples to test and analyze, so as to obtain the types and contents of elements or ions in the samples. This analysis meets customers' requirements for elemental ion analysis by identifying and quantifying elements/ions in the samples.
Testing Methods
- Atomic Emission Spectrometry
- Ion Chromatography (IC)
Instrument Technical Parameters
- Resolution: 0.1 ppm
- Stability: Typical signal drift within 8 hours is less than 1% without internal standard correction or any form of drift correction.
Sample Submission Requirements and Precautions
- Sample form: Liquid or solid, weighing 100 mg to 5 g.
- Solubility: Samples must be fully soluble in common inorganic solvents (e.g., water, sulfuric acid, hydrochloric acid, nitric acid, aqua regia, etc.).
