Gas Detector Tube Applications
The gas detector tube has many applications and advantages
which other analysis methods do not have:
Measurement of working environment: The gas detector tube is used
for quickly measuring concentrations of harmful gases and vapours in the working
environment and establishing the concentration of gases and vapours in work sites. It is also
used for the measurement of comparatively thick harmful gases or vapours in open tanks,
painting rooms, plating tanks, electrolytical cells, storage sheds and gas leak
areas,
as well as establishing the efficiency of exhaust systems, ventilators and air purifiers.
Measurement for the environmental sanitation of buildings and
offices: In a closed room, the concentrations of harmful gases, such as
Carbon Monoxide and
Carbon Dioxide, are increased by respiration of human bodies. Measuring the efficiency of
the ventilation by using gas detector tubes is effective for human bodies and working
efficiencies.
Measurement for the sanitation of schools and as teaching
material: It is widely used as teaching material for health education, physical education
and science.
Measurement of pollutants in the atmosphere: In this case, it is
necessary to measure much lower concentrations than the allowable concentration for
industrial hygiene. That is because the allowable concentration for a living environment
should be considered to be 1/10 to 1/100 of that for industrial hygiene. Gas detector
tubes can be also used for this purpose.
Measurement of pollutants in flue gas: Measurement of pollutants
in flue gas is important for the prevention of air pollution. For
example, the Japanese Industrial
Standards (JIS) provide various kinds of test methods as analysis methods for flue gas, of
which the simplest one is the gas detector tube method. All other methods
are far more
complicated.
Measurement of harmful gases in ships: It is used for the
measurement of harmful gases in ships in conformity with the IMO rule.
Process control: When gas is used as a raw material in chemical
and other industries, a small quantity of impurity can poison the
catalyst or reduce the quality of the products. Therefore, it is necessary
to measure and control this very small quantity of impurity. Furthermore, it is necessary
to measure impure gases in products, mixing ratios of gas materials and composition of
exhaust gas. The gas detector tube is used for testing the purity of gas in this type of
quality control.
Mine safety: Pit fires or gas explosions caused by the spontaneous
ignition of coals in the pit frequently occur in mines. Such spontaneous ignitions can be
discovered at an early stage by detecting a very small quantity of Carbon
Monoxide or of
Ethylene co-existing with the Carbon Monoxide by using detector tubes. The detector tube
is also used for the measurement of Carbon Monoxide after pit fires or explosions.
Prevention of gas explosions: The concentration of inflammable gas
in air or gas can be measured safely and quickly by the detector tube method. The
measurement does not require any power source such as battery or heat source, so can be
performed without any danger, providing no ignition source, even in the presence of
explosive mixed gas. For instance, tank explosion accidents can be prevented by measuring
Acetylene generated in the carbide tank or tank lorry.
Combustion inspection of gas
apparatus: The combustion condition
of gas apparatus after gas conversion can be inspected by using detector tubes
for Carbon Monoxide.
Measurement of alcohol in a drunken person's breath: breath
alcohol detector tubes are used by police stations for the control of driving by drunken persons.
Others: Detection of arsenic in foods; measurement of formaldehyde
vapour generated from textile products; measurement of various kinds of ion.
