What Factors Will Cause Errors In The X-ray Orientation Analyzer?

Posted by tongdaedith on Apr 17, 2019 in News |

The X-ray Orientation Analyzer tablet is not smooth, resulting in a non-smooth analytical surface that affects the measurement results.

The vacuum degree of the optical path is not suitable, and the spectroscopic crystal and the filter are not selected well, which causes interference of various rays and affects the analysis.

The X-ray tube voltage and current are unstable, resulting in fluctuations in the results.

Over time, the positional change of the internal component size of the X-ray directional analyzer causes a change in the intensity of the primary X-ray, or a scar on the anode of the X-ray tube, and the target element is deposited in the window, causing an error in the analysis result.

The change in temperature causes a change in the interplanar spacing of the spectroscopic crystals, thereby affecting the spectral efficiency. It is proportional to the high-pressure drift of the counter tube, and the temperature change causes the gas composition in the tube to change, affecting the magnification.

The drift of the electronic circuit, the statistical error of the counting, the counting error introduced by the time loss of the detection process, and the like.

Changes in the temperature of the gas, nitrogen, methane gas flow, temperature, etc., will affect the absorption of the X-ray directional analyzer by the gas in the optical path. Therefore, once the pressure reducing valve of the cylinder is adjusted, do not move it at will, especially when replacing the new gas, you must try to adjust the air pressure several times. Otherwise, the airflow and air pressure are unstable, resulting in errors.
