Product Description
Spectral rod refers to a special graphite pure rods used for spectral analysis. Graphite can be used for spectrochemical analysis of all elements except carbon, emission spectrum, atomic absorption spectrum, gas analysis and other fields. The spectral analysis graphite electrode uses low ash high-quality petroleum coke as raw material, which is calcined, crushed, kneaded, baked, impregnated, graphitized and purified. At present, we can generally achieve ash content ≤ 5PPM, and adopt clean room dust-free packaging to ensure that the products meet the high purity requirements of spectral analysis applications.
We have many sizes of conventional specifications, such as ∮6*300, ∮8*300, ∮10*300, ∮13*300, ∮15*300, etc., which are convenient for customers to choose.
