FISCHER GOLDSCOPE SD 550 Precious Metal Analyzer

Description

FISCHER GOLDSCOPE SD 550 Benchtop XRF Precious Metal Analyzer – High-Precision Gold, Silver & Jewelry Testing System

The FISCHER GOLDSCOPE SD 550 is a professional benchtop X-ray fluorescence (XRF) analyzer designed specifically for the fast, precise and non-destructive analysis of gold, precious metals, jewelry and metal alloys.

The SD 550 is part of the GOLDSCOPE SD family from Helmut Fischer, which is designed for precious-metal analysis, authenticity testing and value determination. The manufacturer positions the GOLDSCOPE SD 515, 520 and 550 models for applications including gold buying and selling, jewelry, refineries, assay offices and banking.

The GOLDSCOPE SD 550 combines a peltier-cooled silicon drift detector (SDD), DPP+ digital pulse processing, interchangeable apertures and primary filters, and an integrated optical camera for accurate sample positioning.

Key Features

High-Performance SDD Detector
The GOLDSCOPE SD 550 uses a peltier-cooled silicon drift detector (SDD) designed to provide high detection accuracy and high spectral resolution for precious-metal analysis.

This makes the SD 550 suitable for applications requiring detailed analysis of gold and other precious-metal alloys.

DPP+ Digital Pulse Processing
The DPP+ digital pulse processor provides higher count rates and significantly shorter measurement times while maintaining measurement performance. Fischer identifies DPP+ as a key feature of the GOLDSCOPE SD series.

For the SD 550 DPP+ configuration, published specifications indicate highly repeatable gold measurements with measurement times of approximately 15 seconds under specified conditions.

Four Interchangeable Apertures
The SD 550 features four selectable apertures/collimators:
Ø 0.2 mm
Ø 0.6 mm
Ø 1.0 mm
Ø 2.0 mm

The smallest measurement spot can be approximately 0.3 mm, depending on measurement distance and aperture configuration.
This provides flexibility for both larger samples and detailed measurements on smaller jewelry areas.

Six Interchangeable Primary Filters
The system supports a six-position interchangeable primary filter system, allowing measurement conditions to be optimized for different materials and analytical requirements.

Integrated Video Microscope
A high-resolution CCD color camera provides optical monitoring of the measurement location.

Features include:
Crosshairs
Calibrated measurement scale
Spot indicator
Adjustable LED illumination
Digital 1×, 2×, 3× and 4× zoom
This makes precise positioning of jewelry and other samples easier before measurement.

Bottom-Up Measurement
The SD 550 uses a bottom-up measurement direction. The sample is positioned above the measurement window while the X-ray source and detector assembly are located beneath the sample stage.
This arrangement provides convenient sample positioning for jewelry, coins and other precious-metal objects.
