An automated analysis instalment operates to detect inadequate dispensation of a fluidic substance on a tray. The instrument includes an image capturing device to capture an image of at least a portion of the tray including a receptacle portion and a surrounding portion around the receptacle portion. The instrument then identifies the surrounding portion of the at least the portion of the tray in the image, evaluates color components of the image corresponding to the surrounding portion of the at least the portion of the tray, and determines whether the fluidic substance is present on the surrounding portion of the at least the portion of the tray based on at least one of the color components.
