Atomfair Gold Testing Solution: Adsorption Foam & Dedicated Analyzer
1. Gold Testing Preprocessing Procedure (International Standard Compliance)
Weigh 10g of the geological exploration sample into a 35mL crucible, place it in a high-temperature furnace, and calcine at 700°C for 1 hour.
After cooling, transfer the calcined sample to a 200mL ore dissolution bottle, add 20mL of 1:1 aqua regia, and dissolve in a hot bath for 90 minutes.
Take out the ore dissolution bottle, add 80mL of water and the gold-adsorbing foam, then oscillate on a shaker for 40 minutes.
Remove the foam, rinse it thoroughly with water, and place it into a colorimetric tube containing 10mL of eluent (composed of 0.1% and 1% thiourea and salt water).
Elute in a boiling water bath for 30 minutes, take out the foam, and wait for the eluent to cool before conducting instrumental testing.
2. Gold-Adsorbing Foam (Atomfair-GAF632)
2.1 Core Performance
– Low Blank Value: Selected through strict experiments, the foam has extremely low blank values (typical range: 0.06 – 0.27 ng/mL for high-performance models), ensuring no interference with trace gold detection.
– High Adsorption Efficiency: For standard gold samples of different concentrations (1 ng/mL, 5 ng/mL, 10 ng/mL), the recovery rate ranges from 86.0% to 97.7%, showing excellent adsorption and enrichment capabilities for gold elements.
– Unified Standard Specification: Pre-cut into easy-to-use uniform sizes based on experimental verification, compatible with various gold testing analytical instruments, and convenient for direct use in preprocessing operations.
2.2 Application Scenario
Specialized for the preprocessing enrichment of gold elements in geological exploration samples, matching with analytical instruments such as atomic absorption spectrometers, ICP-MS, and dedicated gold testers to improve the accuracy and efficiency of trace gold detection.
3. Dedicated Gold Tester (Atomfair-GTA815, Flame Atomic Fluorescence Spectrometer)

What is the recovery rate of the Atomfair-GAF632 gold-adsorbing foam for trace gold in geological samples?
The Atomfair-GAF632 foam achieves a recovery rate of 86.0% to 97.7% for standard gold samples at concentrations of 1 ng/mL, 5 ng/mL, and 10 ng/mL, demonstrating high adsorption and enrichment efficiency. This performance is critical for accurate trace gold detection in geological exploration.
How does the Atomfair-GTA815 gold tester integrate with the Atomfair-GAF632 foam in the complete testing workflow?
The Atomfair-GTA815 flame atomic fluorescence spectrometer is specifically designed to match the Atomfair-GAF632 foam, forming a complete testing solution. The foam pre-concentrates gold from dissolved samples, and the eluted solution is then analyzed by the GTA815, which has a detection limit for Au of <0.05 ng/mL, ensuring high-precision measurement of trace gold.
What are the operational and cost advantages of using the Atomfair-GTA815 for batch gold testing?
The Atomfair-GTA815 offers a test repeatability of <0.6% and a testing speed of approximately 5 seconds per sample, significantly improving efficiency for batch samples. Additionally, the cost per sample test is only about 0.1 yuan, reducing long-term testing expenses, making it ideal for geological exploration and mineral processing.
The Atomfair Gold Testing Solution integrates the GAF632 adsorption foam and GTA815 flame atomic fluorescence spectrometer into a complete workflow for trace gold analysis in geological samples, with documented recovery rates of 86.0–97.7% and a detection limit below 0.05 ng/mL.
Positive
- High adsorption efficiency: The GAF632 foam achieves 86.0–97.7% recovery for standard gold samples at 1, 5, and 10 ng/mL, enabling reliable enrichment of trace gold from geological matrices.
- Low blank values: Typical blank values of 0.06–0.27 ng/mL minimize background interference, supporting accurate detection of ultra-trace gold concentrations.
Trade-offs
- Multi-step manual preprocessing: The procedure requires calcination, aqua regia dissolution, shaking, and elution steps, demanding careful timing and manual handling that may increase operator workload and potential variability.
- Harsh chemical and thermal conditions: The use of aqua regia and high-temperature furnace (700°C) necessitates appropriate laboratory infrastructure, fume extraction, and safety protocols to manage corrosive fumes and thermal hazards.
