This unique patent pending S1 TITAN accessory protects the detector window from being punctured by sharp objects like scrap shavings and wire, while still allowing rapid and accurate analysis of almost any material. This protective shield minimizes the chance that the detector will be damaged, thus avoiding the cost and hassle associated with the replacement of a broken detector window. This protection does not sacrifice any of the analytical performance of the instrument, even for the light elements like magnesium, aluminum and silicon.
