MATHESON Compressed Gas Notes Gas Mixtures for Proportional and Geiger Counter Units Many years of experience a r e behind each Matheson gas mixture for radiation counters. We manufacture all of the gas mixtures used in nuclear flow counters. These gases a r e mixed and stocked by our three plants in the United States a t East Rutherford, New Jersey; Joliet, Illinois and Newark, California and by Matheson of Canada, Ltd. in Whitby, Ontario. Nuclear counting gas mixtures a r e quality controlled for stable results and long plateaus in the Geiger region. You can be assured of the quality of these mixtures since The Matheson Company is the basic producer of all kinds of gas mixtures from carefully analyzed calibrating mixtures to mixtures used for fumigation. Because we also supply the individual components and because of our complete familiarity with all compressed gases, you can have further assurance of t h e quality of the component and the ultimate quality of the gas mixture itself. These gas mixtures a r e supplied for proportional counters: 9 0 % A r g o n — 1 0 % Methane t 9 6 % Helium — 4 % Isobutane
These gas mixtures a r e supplied for use in Geiger counters: t l . 3 % Butane — 9 8 . 7 %
Helium
t O . 9 5 % Isobutane — 99.05% Helium
In addition to the above mixtures we can also supply any gas mixture to meet particular specifications for such instruments. Prices Complete information as to cylinder size, contents in cubic feet and regulator inlet designation as well as prices a r e shown in our current catalog. Send for a copy. With transportation costs a factor because of cylinder weight, you will be pleased at the economy of dealing with Matheson a t our conveniently located shipping points. Equipment Our field men find t h a t expensive Nuclear Counters a r e sometimes installed with inexpensive industrial regulators which are a source of trouble in the entire operation. We urge you to complement your nuclea; counters with good laboratory regulators. Matheson is a source for such regulators and we particularly recommend our No. 8-350 two stage regulator. Our catalog presents extensive information on a broad range of automatic regulators. The Matheson Company supplies 86 different compressed gases.
