The object of the invention is to provide an analytical instrument (25) for use with profile diagrams (1) of materials to monitor and determine whether the detection systems producing such profile diagrams (1) are functioning properly, and to quickly pin-point and identify, among known materials exhibited by such profile diagrams (1), unknown materials exhibited by such profile diagrams (1).
Said analytical instrument (25) has a flat, rectangular-shaped body (29) with three horizontal and parallel slots (61), (63) and (65) formed therethrough and markers (43) of different colors that are adjustably disposed relative to such slots (61), (63) and (65) and secured therewith.
