3.10.3.3. Transmission synchrotron X-ray powder diffraction (SXRPD)

| top | pdf |

Powder patterns for the lowest analyte content samples, CGpQ_0.12A and GFL_0.12X, were also measured using synchrotron radiation. SXRPD data were collected in Debye–Scherrer (transmission) mode using the powder diffractometer at the ALBA Light Source (Fauth et al., 2013[link]). The wavelength, λ = 0.77439 (2) Å, was selected with a double-crystal Si(111) monochromator and was determined using the NIST SRM640d Si standard (a = 5.43123 Å). The diffractometer is equipped with a MYTHEN-II detector system. The samples were loaded into glass capillaries 0.7 mm in diameter and were rapidly rotated during data collection to improve the diffracting-particle statistics. The data-acquisition time was 20 min per pattern to attain a very good signal-to-noise (S/N) ratio over the angular range 1–35° 2θ. Three patterns, taken at different positions along the capillaries, were collected for each sample.

SXRPD data for the amorphous content series, CZQ_xGl, were also measured at the ALBA Light Source. The experimental setup was the same as described above but the working wavelength was λ = 0.49591 (2) Å.
