The GoldXpert for gold testing and non destructive precious metals analysis is equipped with an articulating sample-holder arm to secure and orient samples for analysis. The sample holder is ideal for small-component and mixed-metal jewelry testing.
The GoldXpert is available in two configurations: the standard GoldXpert and the high-performance GoldXpert SDD. The GoldXpert SDD is equipped with an advanced Silicon Drift Detector, enabling better precision and sensitivity for the most critical of applications.
The GoldXpert SDD offers a two-fold improvement in precision and sensitivity over the GoldXpert. For example, for a 20-second long test on an 18 kt gold standard, the GoldXpert will yield an Au precision of ±0.125%, while the GoldXpert SDD will yield an Au precision of ±0.067%. Longer testing times provide better precision. Shorter testing times can be utilized for rough, approximate analysis.
The GoldXpert SDD is recommended for refiners who need the utmost in analytical precision and fast reading times. The standard GoldXpert is suggested for general karating and trading applications.
