Product Description

Graphite spectral rods are widely used in emission spectroscopy, atomic absorption spectroscopy, and gas analysis for spectral analysis purposes.

Features

Graphite spectral rods have good thermal conductivity, oxidation resistance, strong thermal shock resistance, high purity, low ash content, low thermal expansion coefficient, and can be machined well, etc.

Applications

Auxiliary Electrode: Graphite spectral rods are often used as auxiliary electrodes for liquid samples or poorly conductive samples to conduct electricity and collect ions in spectral analysis.

Spectral Emission: By heating the graphite spectral rod, the chemical elements in the sample release energy and produce specific spectral lines, thus determining the chemical elements in the sample and their contents.

Atomic Absorption: Graphite spectral rods are also used in atomic absorption spectroscopy for detecting the concentration of metal ions in the sample, etc.

Gas Analysis: In addition to liquid samples, graphite spectroscopy rods can also be used for gas analysis by detecting the composition and content of gas samples.

In short, graphite spectral rods play an important role in various spectral analysis techniques, helping to determine the chemical composition and content of the sample.

Our high-purity graphite rods are specially designed for use in the field of spectral analysis. Currently, they generally achieve an ash content of < 5PPM, with < 2PPM already achieved. We are actively working to develop even higher purity levels.
