Characteristics of k-1688 handheld X-ray fluorescence spectrometer

1. Small power (4W, 35kV fixed high voltage) end window integrated micro light tube is adopted, with low power consumption and high excitation efficiency. Combined with the use of large-area beryllium window electrically cooled Si PIN detector, the handheld instrument

It has the test performance of geological ore samples similar to that of desktop computer.

2. Small size, portable, convenient for field work. On site analysis and in-situ analysis anytime, anywhere.

3. Using high-resolution PDA as the host, combined with the patented technology of micro multi-channel analyzer, the instrument is convenient and flexible, and the test data are in the palm of your hand in any environment.

4. The instrument can not only carry out rapid test by hand, but also carry out fine test on samples for a long time by using vertical seat.

5. The instrument is waterproof and dustproof, and can be used continuously in high temperature and high humidity environment. Its protection box is designed with high-strength military articles, with good moisture-proof, shockproof and pressure proof functions.

6. Professional software, the application software for alloy element detection, has the characteristics of high sensitivity, short test time, simple operation and little restriction on operators.

7. Rapid identification of alloy categories, automatic multi-element qualitative and quantitative analysis, selection of multiple ore sample modes and free addition of unlimited number of modes, built-in strength correction method,

The deviation caused by samples with different geometric States and uneven structural density can be corrected.

8. One battery can be used for 4 hours to ensure testing anytime, anywhere.

Technical index analysis:

The technical indexes for evaluating the quality of an instrument are multiple and comprehensive. Users mainly care about and value the range of analysis elements, that is, what we usually call analyzable elements, the length of analysis time, accuracy, etc. The importance of technical indicators ultimately depends on the purpose of application.

Myth 1: one sided pursuit of accuracy: when it comes to the performance of the instrument, it is often natural to take the accuracy of the result as the only judgment standard, and a lot of energy will be used to judge the "accuracy" of the instrument in daily application. The most common thing is to "check the result" with chemical analysis. Accuracy is important, but as for industrial analysis, precision must not be ignored. The first thing to pay attention to is precision, that is, the results of multiple measurements of the same sample should have good consistency, and the difference between each measurement result and the mean value should be small enough. As for the difference between the measured value and the true value, it often belongs to systematic deviation and can be mathematically corrected.

Myth 2: do not pay attention to stability and reproducibility. The so-called stability refers to the standard deviation of multiple consecutive measurements (usually 21 times) of the same sample, while the reproducibility refers to the consistency between the results measured again after a long interval of the same sample. These two indicators are the key indicators of industrial analysis instruments. The results of industrial analysis are mainly used for production process control and parameter adjustment. The relative change of analysis results is directly related to process control and adjustment. The accurate measurement of relative change is based on stability and repeatability.

Myth 3: the shorter the analysis time, the better. X-ray measurement is a statistical measurement of random events, which is determined by the statistical law. The amount of counting depends on the measurement time and directly determines the size of the measurement error. A long enough measurement time is the prerequisite for the measurement accuracy. In order to ensure the measurement accuracy, there must be enough measurement time.

Myth 4: pay more attention to price than service. Of course, price is an important factor in purchasing goods, but it should not be a decisive factor. The quality and price of each part of the analytical instrument vary greatly, and directly determines the price of the instrument. It is difficult to ensure the quality simply by pursuing cheap price. For equipment such as handheld alloy analyzer, service is often more important. The services mentioned here refer not only to installation and commissioning, supply of spare parts, maintenance services, etc., but also to application technology services. For most users, they do not have their own research and analysis technology and use it to guide applications. In this case, technical services are particularly important.
