Depths of the Earth Company’s gas loading device loads gas-phase and gas-phase mixtures directly into precious metal sample capsules for use in high-pressure high-temperature instrumentation, including the QUICKpress.
The original design of this device was conceived by Boettcher et. al (American Mineralogist, Volume 74, page 1383-1384, 1989) for their studies of the solubility of various gases (Ar, Xe, Kr, N2, C02), in silicate melts.
Before Boettcher et al’s invention of the loading device, gas substances were added as liquid- or solid-phase compounds that volatilized or decayed at temperature to release the desired gas phase. The method was labor intensive, often inaccurate, and commonly introduced unwanted elements and ubiquitous water to the system.
