The SkyScan 1275 optional automatic sample changer can accept 16 samples up to 50mm in diameter or 8 samples up to 96mm in diameter or any mixture of large and small samples. Maximum length of the samples is 80mm. The changer is located on top of the scanner, outside the shielded area. All scanned samples can be removed or replaced at any time without interrupting an ongoing scanning sequence.
The scanning protocol for every sample can be adjusted individually. There are three possible selections of scanning protocols: manual selection, automatic selection and repeating scan parameters from the previous sample. In the case of automatic selection of scanning protocol, the control software will firstly measure the size of a sample using the X-ray image at the lowest magnification in multiple angular positions. Afterwards it will adjust the optimal magnification to keep sample fully inside field of view. The automatic adjustment can be overwritten by the operator.
