Argon containers

When a proportional counter is. used in conjunction with a pulse-height selector, the occurrence of an escape peak may vitiate the results. Assume that the counter filling contains argon, whose K edge is at 3.87 A, and suppose that the pulse-height selector is set to select an x-ray line 3f shorter wavelength the intensity of which is to be measured. This line will excite the K lines of argon. To the extent that these lines are... 

A steel tank containing argon gas has additional argon gas pumped into it at constant temperature. Which of the following is true for the gas in the tank ...

Fig. 19. The argon concentration of nickel films grown in a glow discharge vs. bias voltage. Evaporated films grown under similar conditions, but without a discharge, would not contain argon. (From Ref. )...

In 1907 Lord Rayleigh showed that many rocks, such as Matopo granite and syenite from Mt Sorrel in Leicestershire and from Norway, which contain helium also contain argon (68). 

Imagine that you have two identical flasks, one containing chlorine gas and the other containing argon. How can you tell which is which without opening them ... 

Fig. 17.8. MS/MS schematic representation of MS/MS by quadrapole mass spectrometers. (A) Sample entry normally via ESI. (B) Precursor ion selection allowing only the ion of interest to continue through the mass spectrometer. (C) Collision-induced dissociation of the ion within a gas cell normally containing argon to produce fragments. (D) The products of fragmentation are focused and analysed via a ToF-mass analyser.

Oxygen (approximately 20% by volume) and nitrogen (approximately 80% by volume) are the primary components of the atmosphere, but air also contains argon, neon, krypton, and xenon (approximately 1% by volume).

In part because airbag modules, as presently offered, are so extremely expensive, a great deal of research is bang done to develop less expensive and perhaps less risky nonexplosive systems. By 1994, most GM vehicles will have a system that uses no electrical detonator or sodium azide pellets. It will be powered by a pressurized cylinder containing argon gas. These devices are, of course, of little value to the survivor. A CM dealer can explain whether a specific vehicle has these new compressed gas systems. 

Commercial liquid oxygen may contain argon. Morey 3 found the composition of liquid oxygen to be as follows ... 

The number of cubic centimetres of oxygen and nitrogen (containing argon) dissolved in a litre of water saturated with air from a dry atmosphere at 760 mm. pressure at various temperatures are given in the following table 3... 

When quinol is crystallised from aqueous solution in the presence of argon at 40 atmospheres, the solid has the properties of quinol but contains argon which is set free when the quinol is melted or dissolved. The gas molecule is trapped inside a cage of hydrogen-bonded quinol molecules (Powell, 1948). Clathrates are formed by krypton, xenon and such gases as... 

A mixture contains argon, neon, and hydrogen gases. If the partial pressures of these gases are 45.5 kPa, 23.6 kPa, and 85.3 kPa respectively, what is the total pressure exerted by the mixture ... 

A typical 100-watt incandescent light bulb contains argon gas and nitrogen gas. 

Argon is an inert gas used in light bulbs to retard the vaporization of the filament. A certain light bulb containing argon at 1.20 atm and 18°C is heated to 85°C at constant volume. Calculate its final pressure (in atm).
