Introduction
1. Standard Overview
GB/T 43861-2024 "General Rules for Microwave Plasma Atomic Emission Spectrometry" is my country's first general standard for microwave plasma atomic emission spectroscopy (MIP-AES) technology. This standard clarifies the application specifications of MIP-AES in the qualitative and quantitative analysis of metals and some non-metallic elements, and is applicable to sample detection under liquid injection mode.
2. Comparison of the core of the standard framework
| Standard dimensions | GB/T 43861—2024 | ICP-AES comparison | Flame AAS comparison |
|---|---|---|---|
| Sensitivity | ppb level | Better than traditional flame method, up to ppq level | Poor |
| Detection limit | Metal elements: 1 ng/mL; non-metal elements: 5 ng/mL | Metal elements: 0.5 ng/mL | Metal elements: 5 ng/mL |
| Matrix effect processing capability | Good, supports multiple correction methods | Good | Poor |
3. Principle and scope of application of the method
Microwave plasma atomic emission spectrometry (MIP-AES) is a technology that uses plasma excited by microwave energy as a light source to achieve qualitative and quantitative detection by analyzing the wavelength and intensity of characteristic radiation of elements in the sample.
Application case: Heavy metal detection in environmental monitoring
MIP-AES can be used to determine heavy metals such as cadmium and lead in water samples. By preparing a standard solution with a concentration gradient and using the standard curve method for quantitative analysis, the detection limit can reach 0.1 ng/mL.
4. Implementation Suggestions
- Instrument selection and configuration:Prioritize the use of a high-sensitivity microwave plasma mass spectrometer to ensure the stability of the gas path system and the uniformity of the light source.
- Sample pretreatment:For solid samples, it is recommended to use wet digestion combined with microwave-assisted oxidation technology; liquid samples can be directly injected or measured after dilution.
- Interference elimination:Effectively reduce physical and ionization interferences by optimizing instrument parameters (such as carrier gas flow rate, power), matrix matching and internal standard method.
- Quality control:Regularly use certified reference materials for calibration, and establish a complete quality control process, including blank tests, spike recovery tests, etc.
