TITLE: H2O-Ice GDS136 DESCRIPT

DOCUMENTATION_FORMAT: VOLATILE

SAMPLE_ID: GDS136

MATERIAL_TYPE: Oxide

MATERIAL: Water_Ice (Frost)

FORMULA: H2O

FORMULA_HTML: H2O

COLLECTION_LOCALITY: USGS Denver Spectroscopy Laboratory faucet

ORIGINAL_DONOR: made from triply distilled H2O, USGS

CURRENT_SAMPLE_LOCATION: none (evaporated)

ULTIMATE_SAMPLE_LOCATION: none (evaporated)

SAMPLE_DESCRIPTION:

The sample was created by growing ice on a 77K cold finger from water vapor from triply distilled H2O from Gary Olhoeft's lab, USGS, Denver. The sample should have very little contaminants; being essentially pure H2O.

Measured at 77K.
