Why Use X-Ray Gold Analyzer?

Now gold price is very high, and gold analysis method is becoming more important. For example, gold price is USD1500 per ounce; if analysis method tolerance is more than 1%, then customers wills lose as follows:1 ounce loses USD15, 1Kg loses USD15*(1000/31.1)=USD482If a gold buyer buys 5Kg gold every day, then he will lose about USD2410.So for jewelers and gold buyers, choosing a correct gold analysis method and equipment is very important.

There are several methods that can get gold purity. Its advantages and shortcomings show as below:

1. Gold Test Stone: Fast, but not accurate, because different elements component will show the same color, and results will be decided by people’s color vision. Its tolerance is >1%. High purity gold will be easy to get correct results.

2. Electronic Gold Tester: Fast, but not accurate. It can get samples Karat value, but 1K = 4.17%, and its tolerance is >1%. High purity gold will be easy to get correct results.

3. Density method (Scales Gold Tester): Fast, but not accurate and the process is complicated, and different elements component can get the same density. It can get Karat value of samples, but 1K = 4.17%, and its tolerance is >1%. High purity gold will be easy to get correct results.

4. X-Ray Spectrum method (XRF Gold Analyzer): Fast, accurate, and tolerance can be close to Fire Assay. High purity gold will be easy to get correct results, and tolerance is <0.1%; but for low purity gold, not all companies’ gold analyzer can get correct results, and a good analyzer’s tolerance is <0.5%.5. Fire Assay: Accurate, but it is slow and the process is complicated. Just as it’s complicated, different operator will get different results for the same samples, so for high purity gold, tolerance is < 0.1%; for low purity gold, tolerance is < 0.5%.From the above introducing, you can choose different analysis methods based on your application.

1. If you only test high purity gold, such as 90%~99.99%, then all methods can meet your requirement, but density method and Electronic Gold Tester is the most cost-effective method. XRF Gold Analyzer is more expensive and only used for high purity gold.

2. If you buy different purity gold from market, then XRF Gold Analyzer is the most cost-effective method, and its result is close to Fire Assay, but it is faster to get the results than Fire Assay. Please pay attention: not all companies’ XRF Analyzer can get good results, so you must choose a correct XRF analyzer.

How To Choose A Correct XRF Analyzer For Gold Analysis?

Many manufactories can make XRF analyzer, but the performance is very different, just like auto manufactories. Some autos’ appearance is beautiful, but the performance is disappointing. So if you want to buy a XRF analyzer, don’t only keep your eyes on price and appearance. Only in the way will you find the most cost-effective XRF analyzer. Before you want to buy a XRF gold analyzer, you need to make some samples with different gold percentage, and test them by Fire Assay, then test them with different brands’ XRF analyzer. So you will find which one is the most cost-effective, and then choose this one. This step will spend a little money and time. But if you choose a machine which gives you wrong results, then you will lose more. You also need to understand the following 3 points:

1. It is very important to know whether this machine gives you results automatically. If the machine needs to choose different calculation method  and then gives you the result, so how do you know which result is accurate?

2. How many samples do they use for calibration? This is also important. Some companies always tell customers, if the result is not accurate, then you need more samples for calibration. If you have used 200 samples to calibrate machine, but the No. 201 sample is still not accurate, so what customers can do?

3. The performance of all XRF analyzers is the same at high gold percentage, such as gold > 90%, but it will be very different at low gold percentage. So you will know how to prepare samples for machine testing.

In jewelry field, everyone knows that the most accurate analysis method is Fire Assay. But in the actual precious metal business, we can’t test so many samples by Fire Assay as it takes so much time. Jewelers are eager for a quick analysis method on the basis of accuracy (as Fire Assay). XRA (X-Ray Analyzer) series Gold Analyzer will exactly meet jewelers’ requirements. XRA series Gold Analyzer is the most cost-effective XRF analyzer. We ensure that our machines will supply accurate readings close to Fire Assay, and we can quote the lowest price in the world. You are welcome to compare our machines with any other brands.XRA series Gold Analyzer utilizes the software based on Microsoft Windows operation system (include XP to Win7 or Win10 ). The software also has many other excellent functions besides basic analysis, calculation and reports.

Advantages

Completely Intelligent Analysis:A good gold analyzer doesn’t require the operator to know professional knowledge. The operator just needs to put the samples on the measurement window and click “measurement start”. Then the intelligent analysis system will report the sample purity automatically. No complex to do in the whole process. This needs advanced technology. XRA series Gold Analyzer just does like this.Not all XRF analyzers can do like this. For some brands’ XRF machines, the machine can report the purity only after the operator chooses the working curve or calculate method. But the machine will report different results for the same sample if you choose different curves. If so, how do customers know which working curve is right for the sample in advance?

Unique wireless data transmission

We design unique wireless data transmission in hardware, so our machine no need install driver, it can use for any Windows system, include you can use our machine for future Windows system.

Less Standard Samples For Calibration

XRF analyzer needs a certain quantity of standard samples for calibration to ensure the accurate analysis. For some brands’ machine, even though they use so many samples for calibration, they can’t supply accurate readings. So customers will lose much during gold recycling. XRA serious Gold Analyzer applies the most advanced technology. The machine only needs several samples for calibration and supplies perfect readings close to Fire Assay.

Accurate (Analysis Results Close To Fire Assay Result)

XRA series Gold Analyzer uses unique optical technology and calculation method to ensure analysis results close to Fire Assay.Many companies know how to assemble a XRF analyzer, but they don’t know how to optimize the whole system, so even if they can finish complete XRF analyzer, but their results are very far away from Fire Assay results. So we suggest if customers want to buy XRF analyzer, they should make some gold samples, test those samples by XRF analyzers with different brands and Fire Assay method, and then compare the results and choose the most cost-effective machine.

No Strictions For Samples’ Size And Shape

XRA series Gold Analyzer uses small X-ray spot, so it can test samples of different size , even when the sample is a pin. It also supplies average functions so that customers can be easy to get big sample’s results, such as gold bar.

Unique Safety Design

XRA series Gold Analyzer has 4 levels’ safety protection to avoid X-ray leak.Unique Parts Protection System:XRA series Gold Analyzer has unique technology to protect important parts and keep their lives longer.Rapid Analysis:XRA series Gold Analyzer only takes several seconds for qualitative analysis, and 1 to 2 minutes for quantitative analysis.

Visible

There is a camera in the analyzer, so customers can see X-ray spot position from computer screen, and it is easy to print report with analysis point photo.Innovative Idea: Many innovative ideas are integrated into hardware and software, so we have many utility functions to meet different customers’ requirements. But our innovation  is always plagiarized by some competitors.
