The New and Improved S1 TITAN Models

At the beginning of 2021, Bruker released the exciting announcement that the Bruker S1 TITAN pXRF analysers were following in the steps of the TRACER 5g in receiving the new and improved graphene window. This graphene window replaced the use of an 8 µm beryllium window and is paired with the Silicon Drift Detector (SDD) technology. The switch to a graphene window improves the detection of lighter elements due to the increased transmission of lower energy photons (Figure 1). The limit of detection for the lighter elements such as magnesium and aluminium is then significantly lowered, enabling the better quantification of these elements (Table 1).
