Gold Tester & XRF Analyzer

Gold Tester Explained: Definition & Workings

A gold tester is a non-destructive instrument for precise gold testing and metal analysis. Typically using X-ray Fluorescence (XRF), it emits X-rays at a sample. This causes elements to fluoresce unique secondary X-rays, which a detector measures. This process accurately identifies and quantifies elemental composition, ensuring verifiable gold purity.

Purchase considerations of gold testing machine

When purchasing a gold testing machine, you should focus on:

  1. Detection range of elements:Does it support common precious metal elements such as Au, Ag, Pt, Pd, Rh, Cu, Zn, Ni (and their alloying elements).

  2. Accuracy/Resolution (Detection sensitivity):It is generally expressed in ppm, or an error of ±0.01%. The lower the resolution, the higher the sensitivity. Preferred SDD detector.

  3. Test speed: The result is generally available within 30 to 60 seconds. The faster the speed, the more suitable it is for high-frequency use.

  4. X-ray tube power: The common range is 4W to 50W. The higher the power, the stronger the penetration ability and speed, and the more comprehensive the test, but the price and energy consumption also increase.

  5. Protection and safety certification: Whether there is X-ray safety shielding, interlocking of protective doors, and passing the radiation license certification, etc.

  6. Brand and After-sales Service: Is there local maintenance, on-site service, training support and warranty period (suggested to be one year).

How to extend the lifespan of a gold tester

To extend gold tester life & precision, follow these tips:

  1. Wipe the outer shell with a clean soft cloth or lint-free cloth every day to prevent dust accumulation.

  2. Before each use, check whether there are any foreign objects or contamination in the test window and keep it clean and transparent.

  3. Clean fans and vents regularly to prevent blockage and overheating.

  4. Keep room temperature between 15-30°C and humidity below 70%, avoiding moisture or direct sunlight.

  5. Use a voltage stabilizer or UPS to prevent unstable voltage from damaging components

  6. Avoid prolonged continuous high-load use and turn off the cooling regularly.

Gold Tester Usage Precautions and Operational Hazards

Gold Tester Usage Precautions

For optimal operation and safety, always preheat and calibrate the instrument strictly daily. Ensure the protective door is closed before testing to prevent X-ray leakage. It is recommended to use a regulated power supply or UPS to avoid damage from voltage fluctuations. Keep the working environment dry, clean, and well-ventilated, avoiding high temperature and humidity. Crucially, always follow the operation manual and manufacturer's training, refraining from unauthorized parameter modifications.

Operational Hazards

Improper operations can pose significant risks. Starting a test with the protective door open can cause X-ray leakage and radiation damage. Forcibly cutting power or frequently turning the machine on and off can damage the X-ray tube, high-voltage module, or hard disk, leading to system crashes. Operating in a humid, hot, or dusty environment may cause overheating, mainboard dampness, or detector malfunction/short-circuit. Unauthorized modification of software parameters or calibration data can distort results, potentially requiring factory recalibration. Touching the detector window with sharp objects or fingers will damage the detector film, incurring extremely high maintenance costs. Lastly, moving the sample or opening the door during a test causes sample position shifts, leading to test failure and X-ray exposure.
