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)

3.1 Key Technical Indicators (International Standard)

– High Sensitivity: Detection limit for Au (gold) < 0.05 ng/mL, enabling accurate detection of trace and ultra-trace gold content.
– Excellent Stability: Test repeatability < 0.6%, ensuring consistent and reliable test results.
– Fast Testing Speed: Each sample test takes approximately 5 seconds, significantly improving testing efficiency for batch samples.
– Low Operating Cost: The cost per sample test is only about 0.1 yuan, reducing long-term testing expenses.

3.2 Core Advantages

Designed for efficient and accurate gold content detection, it perfectly matches the Atomfair-GAF632 gold-adsorbing foam to form a complete testing solution. It is suitable for scenarios such as geological exploration, mineral processing, and material analysis that require high-precision gold detection.
