Background of XRF Gold analyzer

How the XRF Gold analyzer works

The atoms of the element emit spectral lines under the action of the excitation light source, and the spectral lines are split by the grating to form a dao spectrum. Each element has its own characteristic spectral line. The intensity of the spectral line can represent the content of the element in the sample. The Litong spectrometer uses a photodetector to convert the radiant energy of the spectrum into electrical energy. The detected output signal is processed and displayed on the readout device. Then, according to the analysis curve made by the corresponding standard material, the content of the element to be measured in the analysis sample is obtained.

A XRF Gold analyzer is a scientific instrument that decomposes complex light into spectral lines. It is composed of a prism or a diffraction grating. The spectrometer can measure the light reflected on the surface of the object.

1: In view of the scarcity and preciousness of precious metals, traditional destructive detection methods such as the blow method have long been unable to adapt to the market. A fast, accurate, and lossless detection method is urgently needed.

2: The adulteration of gold and silver jewelry in the market has been repeatedly banned. Counterfeit products such as gold-clad copper have brought huge losses to merchants and customers. The high efficiency and accuracy of CDOCAST’s spectrometers help merchants avoid this transaction risk

CDOCAST precious metal detection X-ray spectrometer is a high-precision XRF analyzer designed for precious metals and jewelry detection. The measurement process only takes a few seconds; the measurement result unit is displayed as% and carat.

XRF Gold analyzer can also be used to detect coatings and non-standard alloys. The instrument can be operated using the embedded display screen or the CDOCAST software installed on the PC. CCD camera is applied to achieve precise sample positioning. Automatic variable collimator, required measuring point size is free to choose

CDOCAST XRF Gold analyzer is equipped with high-precision weighing and printing functions, which can print analysis results at any time, including chemical composition, weight, and price, and is equipped with a rechargeable lithium battery for on-site analysis.

FAQ

1: Does the analyzer support the testing of different forms of samples, such as powders, liquids, and solids?

CDO-K5 model supports solids, powders, and liquids analysis and can distinguish between seawater pearls and freshwater pearls.

2: What is the range of detection (in ppm) for the various elements?

The analysis range is 1ppm to 99.99%.

3: How does the Si-pin detector contribute to the accuracy of measurements, and are there alternative detector options?

The main characteristic parameter of a detector is energy resolution. We usually judge the quality of a detector based on the numerical value of energy resolution. The higher the resolution of the detector, the higher its testing accuracy. K5 adopts Si-pin detector, we also have other models with Gas proportional detector (worse than Si-pin) or SDD detector (better than Si-pin).

4: What is the calibration process for ensuring precise elemental analysis, and how often does the analyzer need recalibration?

The machine is equipped with a silver calibration sample. The machine needs to be calibrated once a day after being turned on.

5: How does the system handle inter-element interference in complex sample compositions, and what measures are in place to minimize this interference?

The higher the resolution of the detector, the better it can handle interference between elements and very adjacent elements.

6: How frequently do components such as the X-ray tube or Si-pin detector need maintenance or replacement?

The X-ray tube is the only consumable in the spectrometer, and its lifespan is approximately 10000 hours, sometimes even longer.

7: How does the analyzer deal with overlapping spectral lines during element detection, especially for closely related elements?

The interference between elements and very adjacent elements is mainly processed through detectors.

8: Does the XRF analyzer support customizable test profiles for different materials, or is the software fixed to predefined element ranges?

We can customize different testing configuration files according to customer requirements.

9: What are the payment terms, and is a deposit required before production?

Payment term: T/T 50% in advance, balance before shipment; or T/T100% in advance. We usually have stock available, and machines can be shipped after simple debugging for 1-2 days.

10: Are there any hidden costs or recurring fees, such as for software upgrades or spare parts?

Our software will be updated every year and we provide free upgrades for our customers at no additional cost.

11: What is the specific warm-up and stabilization process for the X-ray tube and detector, and how does it minimize measurement drift over extended periods of use?

Preheating the machine for 5 minutes every day can extend the lifespan of the hardware. Calibrate the sample with a silver sheet at regular intervals every day to determine if the channel is drifting. Under constant temperature and humidity conditions, it can ensure maximum stability of testing and prevent drift.

12: How many samples can be processed in an hour/day, assuming average sample complexity, and what factors influence this rate?

The machine can work continuously, and the test time is adjustable. Assuming a testing time of 60 seconds (standard time), 60 samples can be tested in one hour.

13: What are the specifications of the X-ray tube (voltage, current, anode material), and what is its expected operational lifespan under typical use conditions?

The material of the X-ray tube is tungsten target, with a specification of 50KV (voltage) and 1mA (current). This is the limit case, and the actual use is smaller than it. Its lifespan is approximately 10000 hours, sometimes even longer.

14: How is the detector cooled (air or thermoelectric), and what is its impact on system longevity and measurement accuracy over time?

The detector is cooled by Electric refrigeration. Constant temperature and humidity, as well as a stable voltage environment, can ensure the lifespan and testing accuracy of the machine system.

15: Can the analyzer measure the thickness of coatings or platings on materials, and if so, what is the resolution and precision for such measurements?

The detection depth is usually 30 microns.

16: Is there a warranty, and what kind of technical support or updates will be provided post-purchase?

Our warranty is 1-2 years, depending on different models, and we provide lifetime technical service support. Our software will be updated every year and we provide free upgrades for our customers.
