Analytical Objective

An unknown high voltage discharge tube contains a random mixture of exactly two distinct gases chosen from the reference elements on the side. Drag the Spectroscope Viewfinder vertically until it aligns level with the tube to read its combined emission fingerprint. Compare the overlapping lines against the known spectral sets to cross-reference and isolate the mystery gases!
