Graphite Electrode

This high-purity spectral graphite electrode is designed specifically for Optical Emission Spectrometry (OES). Using high-density, high-conductivity graphite with specialty purification, impurity levels are kept below ppm levels to avoid background interference. Its precision cup or cone design ensures stable discharge excitation and uniform sample evaporation. Widely used for metal composition testing, oil additive element analysis, and soil testing, it is an essential consumable for multi-element rapid determination.
