History and Applications
HISTORY OF DESIGN AND COMMON USEAGE
Long before HG became an environmental exposure issue , which made obsolete the traditional method, a major oil company contacted
Emdyne, Inc., in the early 1980’s, to help with the design of a mechanical volume recording instrument for their core flood
laboratory studies. After about 2 years, a first generation design reached completion and numerous iterations were built for the
oil company’s in house use in their tertiary oil recovery research labs. The design proved to be reliable and accurate for their
purposes. A patent was granted the design in the mid 1980’s.
At this time, two other patents were granted for related lab equipment: an Oscillating Back Pressure regulator, and a Dual
Piston continuous flow high pressure, low pulse pump. These designs are no longer produced by Emdyne Inc.. The Emdyne Gasmeter is
a more general instrument and is surviving in its present form thanks in large part to the collaboration of an industry leader in
geological core analysis.
When this new company became aware of a Gasmeter example in Canada in the late 1990’s, a call came to Emdyne to look into
redesigning the basic unit to include several improvements not incorporated in the original units. A thorough redesign program
then ensued, a prototype was made and tested, further changes were added and a final design arrived in about the year 2000. This
explains the MK 2000 designation on the instrument front panel.
Although the Gasmeter has been used primarily for core flood studies in the oil and gas business, it can be exploited for other
potential uses in industry. These may include:
High School and University Chemistry Departments
Chemical Manufacturing and research laboratories
National Research and development laboratories
Defense Industry program development and analytical studies
Precise Sample collection for manufacturing process quality control
Aerospace Science research and analysis
