Question

In X-ray spectrometers, the specimen or the sample is placed after which of the following components?

• A. X-ray tube
• B. Monochromator
• C. Collimator
• D. Detector

Hint:

\textbf{Tip:} Always remember—X-ray emission starts from the tube, and the sample comes right after it to interact with the primary beam.

Answer 1

The Correct Option is A

In an X-ray spectrometer, the X-ray tube is the source of X-rays.
The specimen or sample is placed immediately after the X-ray tube so that it can interact directly with the emitted X-rays.
This interaction allows for characteristic X-ray emission from the sample, which is then analyzed by other components like the monochromator and detector.
Therefore, the correct placement of the specimen is directly after the X-ray tube.
