1Regarding the detection of low power and trace substancesdoubt:Terra/BTXLight tube voltage30KV, tube current300UACan trace substances be detected with such low power and ensure detection accuracy? Answer: Reason:1）Two-dimensional surface detector-CCD：Terra/BTXUsing a two-dimensional surface detectorCCDCollect Laue spot information throughout the entire diffraction plane,Traditional large desktop computers use one-dimensional counters, which can only collect information from one cross-sectional segment of the Laue spot. Therefore, the amount of information collected by the detector is large enough.2）Sample vibration technology（NASA）Large desktop computers use reflection diffraction geometry technology and step scanning, with the tested sample kept fixed, and are used for measurementThe angle analyzer achieves specific angle screening, diffraction, and counting, with only one diffraction plane of one grain in each phase enteringPerform a diffraction once.Terra/BTXUsing transmission diffraction geometry technology and sample vibration technology, the measured substance is5000HZThe frequency vibration enables specific angle screening, and at the same time, a diffraction surface of one grain in each phase can achieve multiple diffractions due to sample vibration, thereby converting smaller incident beam energy into larger diffraction outputenergy3)By using sample vibration technology, the focal spot area was indirectly increased, allowing all samples in the sample chamber to participate in diffraction and improving statistical performance.4）Terra/BTXProduced by the light tubeXThe optical path distance between the radiation beam and the sample<0.5cmIt can effectively reduceXScattering of light beams to maintain effective beam intensity; Large desktop computers use angle measurement systems,XThe optical path distance between the beam and the sample>10cmThis way, the scattering is more obvious and requires higher power to ensure the illumination of the sampleXBeam intensity.
2Regarding15mgDetection quantity and representativeness of detectiondoubt:Terra/BTXThe sample size only needs to be tested15mgHow can such a detection amount ensure the representativeness of the sample and sufficient diffraction information? Reply:Terra/BTXThe reason why the amount of samples detected by the instrument is greater than that of large desktop computers is that the samples detected by the instrument are onlyXThe part of the beam that is irradiated and diffracts. Large desktop computers require many samples during the sample preparation process, but only one sample is actually detectedXThe area of the beam focal spot is generally only3-5mmConsidering its penetration performance, overall, the detectedThe sample size is10mg左右。Terra/BTXDue to the sample vibration system, all samples added to the sample chamber can be guaranteed to undergo high-speed vibrationXThe beam illumination detected it, therefore, its measurement is all the quantities added during sample preparation.3Regarding the elimination of selective selection orientationLarge desktop computer: During sample preparation, press and scrape the tablets, especially the scraping step. Therefore, the elimination of its preferred orientation mainly lies in the quality of sample preparation.Terra/BTXThe existence of a sample vibration system means that during testing, all samples will be subjected to5000hzThe frequency immediately vibrates, thereby eliminating the preferred orientation.
4Regarding the exclusion of fluorescence effectsXAfter the beam irradiates the sample, various phenomena such as absorption, scattering, fluorescence, diffraction, etc. will occur. When the detector receives this information, it is often indiscriminate and manifested in the diffraction pattern. Diffraction is the characteristic peak, while fluorescence, scattering, absorption, etc. are manifested as background and noise. Especially, the fluorescence effect is harmful to diffraction analysis.Terra/BTXUsing materials that are highly sensitive to energyCCDDetector, capable of distinguishing fluorescence energy, scattering energy, and diffraction energy, and generating three types of diffraction data respectivelyKaTXT/Film TXT/Thresh TXTEliminate fluorescence effects.
