Alpha Resources crater electrode pedestal (l= 1.5", od= 0.12") is a high-purity graphite electrode for arc/spark optical emission spectroscopy (OES). Precision-machined for consistent gap geometry and stable arc characteristics, it supports repeatable excitation and low blank levels in elemental analysis.
Supplied by Alpha Resources as an aftermarket laboratory consumable.
