Spectrometers have been widely used in agriculture, animal husbandry, food, and chemical industries in recent years due to their excellent transmission characteristics and ease of operation. This provides a vast space for scientific research and teaching, and then spectral analysis. What are the advantages and disadvantages of the instrument? Spectrometer advantages:
1. The sampling method is flexible. The detection and analysis of rare and precious metals can save the loss caused by sampling.
2. The test rate is high, multi-channel instantaneous multi-point acquisition can be set, and real-time output through the calculator.
3. Non-destructive testing can be done for some mechanical parts without damaging the sample for nondestructive testing.
4. Faster analysis, more suitable for pre-fire analysis or field analysis, so as to achieve rapid detection.
5. The accuracy of the analysis results is based on the chemical analysis standards. Disadvantages of the spectrum analyzer 1. It is difficult to accurately detect non-metallic and metal-to-metal elements.
2. It is not the original method and cannot be used as an arbitration analysis method. The test results cannot be used as the basis for national certification.
3. Due to the relatively monopolized factors of the products of various companies, the purchase and maintenance costs are relatively high, and the cost performance is relatively low.
4. A large number of representative samples are required for chemical analysis modeling, which is obviously impractical for small batch sample testing.
5. The model needs to be constantly updated. The model will also change when the instrument changes or the standard sample changes.
6. The cost of modeling is very high, and the test cost of the three-element analyzer is relatively large. Of course, the test cost will decrease when a large number of samples are tested.
7. Affected by external or internal factors such as the parameters of the optical system, the curve nonlinear problem often occurs, which has a great influence on the accuracy of the detection result.
The above are some of the advantages and disadvantages of the spectrum analyzer. According to the survey of North and South instruments, a number of users who use this instrument have found that everyone thinks that it is accurate, portable, and fast, so I think this is the biggest advantage of the spectrum analyzer. .
Heat Insulation Riser used insulation materials and adhesives and other new materials, high-performance heat insulation riser sets. Products can be divided into straight barrel riser, necking riser, torticollis riser, elliptical riser and AN riser. Straight bucket riser, necking riser, inclined neck riser can also provide riser cover, easy to choose your riser, dark risers in the form of two risers. Its low density, high strength and toughness, applicable to all grades of cast steel, cast iron and alloy castings and a variety of molding process. AN low density, small size, accurate, suitable for all kinds of black and non-ferrous metal castings. Can be embedded in the shape of the plate or embedded in the shape after the sand.
Heat Insulation Riser has the advantages of high density, good toughness, large heat capacity and long holding time, so as to prolong the solidification time of the metal liquid, save the metal liquid for filling, reduce the cutting area of the riser and casting, improve the qualified rate of products, Reduce the cost of the effect.
