Single Point and Multi-Point Analysis

A typical micro-XRF instrument such as the XGT systems includes a high precision motorized sample stage, which allows the sample to be very accurately positioned beneath the X-Ray beam. Color video cameras allows the sample to be visualized by the operator. Typical instrument software will enable fast sample positioning by seamlessly linking camera images with sample movement.

In addition to manually aligning the sample so that a specific feature can be discretely analyzed, it is also possible to store in the software a list of positions for analysis. Once these have all been selected and the measurement conditions chosen, the motorized stage will move to each position in turn, acquiring a spectrum at each before moving to the next.

In this manner, different visual features across the sample can be automatically analyzed with ease, or indeed, multiple samples laid out on the sample stage can be analyzed in turn. In this manner, time consuming repeat measurements are done automatically, leaving the instrument operator free for other activities.
