Customers first consider the accuracy, cost performance and after-sales service of any testing equipment. With the rapid development of the machinery industry today, only accurate measurement of the percentage content of elements in steel is possible. Only in this way can products reach national standards.
At present, the five major elements in steel have reached the level of countdown, and the sample sampling has also been upgraded from the original quantitative analysis to the non-quantitative analysis. The end color is changed from the original adjustment to automatic identification. The entire five-element inspection of general steel can be completed within a few minutes.
The non-spectral control of non-ferrous metals (copper alloys, aluminum alloys) in front of the furnace is none other than its multi-channel instantaneous multi-point collection feature to keep the spectrum analyzer quickly detecting the elements that customers want to detect.
There are many types of instruments. Choose a reasonable analyzer according to the needs of your company. ND series analyzers are widely used in smelting, casting, machinery, vehicles, pumps, valves, ores, environmental protection, quality inspection and other industries and fields, which can be carried out quickly and easily. Product testing in the stages of raw material acceptance, pre-furnace analysis, and finished product inspection. The comparison between the spectrum analyzer and the ND series analyzer is now available for customers to choose.
Advantages of ND series five element analyzers
1. The chemical analysis method is the arbitration analysis method used by the national laboratory with high accuracy.
2. The interference between each element can be shielded with chemical reagents, so that the elements do not interfere with each other, and the curve can be nonlinearly regressed to ensure the accuracy of detection.
3. The sampling process is deep in the sample center and multi-point collection, which is more representative, especially for non-uniform samples and samples after surface treatment can be accurately detected.
4. The application field is wide and the limitation is small. A standard curve can be established for measurement, and the instrument can perform curve self-detection.
5. Low cost of purchase and maintenance, relatively simple maintenance.
Disadvantages of ND series five element analyzer
1. The process is more than the spectral analysis method, and the workload is large.
2. Not suitable for rapid analysis before the furnace.
3. The test sample will be damaged due to the sampling process
Advantages of optical spectrum analyzer
1. The sampling method is flexible, and the detection and analysis of rare and precious metals can save the loss caused by sampling.
2. The test rate is high, multi-channel instant multi-point acquisition can be set, and real-time output through the calculator.
3. For some mechanical parts, non-destructive testing can be done without damaging the sample, which is convenient for non-destructive testing.
4. The analysis speed is faster, which is more suitable for pre-furnace analysis or on-site analysis, so as to achieve rapid detection.
5. The accuracy of the analysis results is based on chemical analysis standards.
Disadvantages of the spectrum analyzer
1. It is difficult to accurately detect non-metal and elements between metal and non-metal.
2. It is not the original method and cannot be used as an arbitration analysis method, and the test results cannot be used as the basis for national certification.
3. Due to the relative monopoly of the products of various enterprises, the cost of purchase and maintenance is relatively high, and the cost performance is low.
4. A large number of representative samples are required for chemical analysis modeling, which is obviously impractical for the detection of small batch samples.
5. The model needs to be constantly updated. When the instrument changes or the standard sample changes, the model also needs to change.
6. The modeling cost is very high, and the testing cost is relatively large. Of course, for a large number of samples, the testing cost will decrease.
7. It is susceptible to external or internal factors such as optical system parameters, and the problem of curve nonlinearity often occurs, which greatly affects the accuracy of the detection results.
