TITLE: Sulfur GDS94 Reagent DESCRIPT
DOCUMENTATION_FORMAT: MINERAL
SAMPLE_ID: GDS94
MINERAL_TYPE: Element
MINERAL: Sulfur
FORMULA: S
FORMULA_HTML: S

ORIGINAL_DONOR: Not available
CURRENT_SAMPLE_LOCATION: USGS Denver Spectroscopy Laboratory
ULTIMATE_SAMPLE_LOCATION: USGS Denver Spectroscopy Laboratory
SAMPLE_DESCRIPTION:
Reagent grade sulfur.
IMAGE_OF_SAMPLE:
END_SAMPLE_DESCRIPTION.
XRD_ANALYSIS:
40 kV - 30 mA, 6.5-9.5 keV
File: sulf94.mdi (smear on quartz 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 spacing's and intensities.
