什么是X荧光光谱石油测硫仪?

X射线荧光硫分析仪是一种基于X射线荧光光谱分析的测试光谱仪。

X射线荧光光谱仪(X-ray Fluorescence Spectrometer,简称:XRF光谱仪)是一种快速、无损的材料测量方法。

其原理是用X射线激发源照射待分析的油样。样品中硫元素的内电子被敲除后,引起核外电子跃迁。当被激发的电子回到基态时,硫元素就会被放出。特征 X 射线。探测器接收这些硫元素的特征X射线信号,仪器软件系统将其转换为相应的测试强度。特征X射线强度与硫含量之间的关系是用标准物质样品建立的,即校准曲线。建立不同硫含量范围的校准曲线后,再对未知样品进行检测,即可快速分析石油等液体中的硫含量。

X荧光硫分析仪的优点

1.快速,一个样品通常只需要100秒就可以得到S硫含量

2.准确,测试结果可达到实验室级精度

3.无损。 X射线荧光硫分析仪是一种无损分析。对样品*无损

4、样品制备简单,只需将样品放入5ml专用样品杯中,即可上机测试。

5、使用维护成本低,无需消耗惰性气体

6、操作简单,上手快,无需每天重复校准,大大提高测试效率

7、线性动态范围宽,可分析1mg/L至10000mg/L硫含量

8、不受样品基质的影响,X射线荧光光谱与样品的化学键合状态无关,与固体、粉末、液体、结晶、非晶等物质的状态基本无关。

9、长期稳定性和测试精度高

What is a petroleum/oil X-ray fluorescence xrf sulfur analyzer?

The X-ray fluorescence sulfur analyzer is a test spectrometer based on the analysis of X-ray fluorescence spectroscopy.

X-ray Fluorescence Spectrometer (X-ray Fluorescence Spectrometer, referred to as: XRF spectrometer) is a fast, non-destructive material measurement method.

The principle is to irradiate the oil sample to be analyzed with an X-ray excitation source. After the inner electrons of the sulfur element in the sample are knocked out, it causes the transition of the extranuclear electrons. When the excited electrons return to the ground state, the sulfur element will be emitted. Characteristic X-ray. The Detector receives the characteristic X-ray signals of these sulfur elements, and the instrument software system converts them to the corresponding test intensity. The relationship between the characteristic X-ray intensity and the sulfur content is established with the reference material sample, that is, the calibration curve. After establishing calibration curves with different sulfur content ranges, and then testing unknown samples, the sulfur content in petroleum and other liquids can be quickly analyzed.

Advantages of X Fluorescence Sulfur Analyzer

1. Fast, a sample usually only takes 100 seconds to get the S sulfur content

2. Accurate, the test results can reach laboratory-level accuracy

3. Lossless. X-ray fluorescence sulfur analyzer is a non-destructive analysis. Is completely non-destructive to the sample

4. The sample preparation is simple, only need to put the sample into the 5ml special sample cup, you can test on the machine.

5. Low cost of use and maintenance, no need to consume inert gas

6. Simple operation, quick to get started, no need to repeat the calibration every day, greatly improving the test efficiency

7. Wide linear dynamic range, can analyze sulfur content from 1mg/L to 10000mg/L

8. Not affected by the sample matrix, X-ray fluorescence spectroscopy has nothing to do with the chemical bonding state of the sample, and basically has nothing to do with the state of solid, powder, liquid, crystalline, amorphous and other substances.

9. Long-term stability and high test precision
