Portable intelligent X-ray diffractometers are of great importance in daily work. This device may seem small, but it contains precise technology and strict usage requirements.

Environmental Control and Equipment Preparation

Before using the Olympus portable intelligent X-ray diffractometer, environmental conditions are the first detail to pay attention to. The equipment needs to operate in a temperature specific environment, with temperature changes and relative humidity within a certain range. These parameters are not arbitrarily set, but are based on the working characteristics of the X-ray tube and detector.

Before starting up, the circulating cooling water system must be turned on, which is a key step in protecting the X-ray tube. The circulating water temperature needs to be maintained at a specific temperature, as excessively high water temperature can directly affect the lifespan and stability of the X-ray tube.

Key details of sample preparation

Sample preparation is the core step that affects the accuracy of test results. For solid samples, the surface size should be greater than 10 × 10mm, the thickness should be above 5 μ m, and the surface must be flat.

The powder sample needs to be ground into a particle size of 320 mesh, with a diameter of about 40 microns and a weight greater than 5g. This particle size requirement is not arbitrary, but based on the optimal balance between X-ray penetration depth and diffraction efficiency. Coarse powder can lead to insufficient diffraction intensity, while finer powder may result in preferred orientation issues.

For micro stress measurement of metal samples, it is necessary to prepare metallographic samples and perform ordinary polishing or electrolytic polishing to eliminate surface strain layers.

Professional key points in the operation process

In practical operation, special attention should be paid to the opening and closing of doors. You should first press the corresponding button and wait for the prompt sound to sound before opening the door, otherwise the X-ray will automatically turn off. The opening and closing actions should be gentle to avoid excessive vibration that may cause the X-ray to automatically turn off. This detail is often overlooked by beginners, but frequent accidental shutdowns not only affect work efficiency, but may also cause damage to the equipment.

The angle limitation of the goniometer is another key point: wide angle ≤ 110 °, small angle ≥ 0.5 °, exceeding this range will cause damage to the detector and goniometer. I found during on-site service that some customers modified the angle limit without authorization in order to obtain a wider scanning range, resulting in equipment failure and significantly high maintenance costs.

The sample rack is made of glass and is fragile. It should be handled with care and cleaned promptly after use. This detail may seem simple, but the cleanliness of the sample holder directly affects the background noise level and the detection of weak peaks.

The Olympus portable intelligent X-ray diffractometer is a powerful on-site inspection tool, but only by mastering these usage details can its performance be fully utilized and accurate and reliable analysis results be obtained.
