GOLD PURITY CHECKING INSTRUMENTS Silicon Drift Detector (SDD) – CGX-103 The Silicon Drift Detector (SDD) CGX-103 is an advanced XRF-based gold purity testing instrument designed for enhanced performance, superior spectral resolution, and highly accurate elemental analysis. It uses a Silicon Drift Detector (SDD) instead of a conventional Si-PIN detector, delivering improved sensitivity, faster detection, and greater measurement accuracy for precious metals used in the jewellery industry. The instrument is capable of accurately identifying and analyzing individual metal compositions, making it ideal for jewellery manufacturers, hallmarking centres, laboratories, refiners, and quality control applications. Features • Advanced Silicon Drift Detector (SDD) technology for enhanced performance and spectral resolution. • Higher measurement accuracy compared to conventional Silicon-PIN detector systems. • Detects and analyzes precious and noble metals individually. • Fast and non-destructive elemental analysis. • User-friendly, menu-driven operating software. • Thermoelectric detector cooling for stable and reliable performance. • Suitable for jewellery testing, hallmarking, refining, and quality control. • Built-in computer interface for seamless connectivity. • Compact and robust instrument design. • Designed for high-precision precious metal analysis.
