什么是X熒光光譜石油測硫儀？

X射線熒光硫分析儀是一種基于X射線熒光光譜分析的測試光譜儀。

X射線熒光光譜儀（X-ray Fluorescence Spectrometer，簡稱：XRF光譜儀）是一種快速、無損的材料測量方法。

其原理是用X射線激發(fā)源照射待分析的油樣。樣品中硫元素的內(nèi)電子被敲除后，引起核外電子躍遷。當(dāng)被激發(fā)的電子回到基態(tài)時(shí)，硫元素就會被放出。特征 X 射線。探測器接收這些硫元素的特征X射線信號，儀器軟件系統(tǒng)將其轉(zhuǎn)換為相應(yīng)的測試強(qiáng)度。特征X射線強(qiáng)度與硫含量之間的關(guān)系是用標(biāo)準(zhǔn)物質(zhì)樣品建立的，即校準(zhǔn)曲線。建立不同硫含量范圍的校準(zhǔn)曲線后，再對未知樣品進(jìn)行檢測，即可快速分析石油等液體中的硫含量。

X熒光硫分析儀的優(yōu)點(diǎn)

1.快速，一個(gè)樣品通常只需要100秒就可以得到S硫含量

2.準(zhǔn)確，測試結(jié)果可達(dá)到實(shí)驗(yàn)室級精度

3.無損。 X射線熒光硫分析儀是一種無損分析。對樣品*無損

4、樣品制備簡單，只需將樣品放入5ml專用樣品杯中，即可上機(jī)測試。

5、使用維護(hù)成本低，無需消耗惰性氣體

6、操作簡單，上手快，無需每天重復(fù)校準(zhǔn)，大大提高測試效率

7、線性動態(tài)范圍寬，可分析1mg/L至10000mg/L硫含量

8、不受樣品基質(zhì)的影響，X射線熒光光譜與樣品的化學(xué)鍵合狀態(tài)無關(guān)，與固體、粉末、液體、結(jié)晶、非晶等物質(zhì)的狀態(tài)基本無關(guān)。

9、長期穩(wěn)定性和測試精度高

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
