XRD_ANALYSIS:

40 kV - 30 mA, 6.5-9.5 keV
File: sulf94.mdi (smear on qtz plate)
References: JCPDS #8-247
Found: Sulfur

Comments: Peaks are moderately narrow, most have sharp tips, but the resolution of the alpha1-alpha2 components is poor. Excellent match to JCPDS #8-247 for all interplanar spacings and intensities.
