Abstract

Methods are provided for producing disposable diagnostic test elements and monitoring a property thereof, where such methods include detecting X-ray fluorescent (XRF) signals of one or more metallic components in a composite of first and second layers applied to a substrate using XRF spectrometry, determining a quantity value for each metallic component in a measured area from the XRF signals, and then calculating an areal coating quantity of the first and the second layers using the quantity values of the metallic components. Additionally or alternatively, the methods can include determining a batch specific code from the XRF signals that can be used when performing a test with a test element. Further provided are systems for monitoring a property of disposable test elements.
