More information about acetylene (C2H2) as a test gas

Acetylene gas, with the molecular formula C2H2, is a colorless, flammable gas that also has a slightly ethereal, often garlic-like odor. It consists of two carbon atoms and two hydrogen atoms. There are no natural deposits on earth, which is why acetylene is only produced industrially - usually via high-temperature pyrolysis or the reaction of calcium carbide with water, which is rarely the case today. The range of uses for acetylene is relatively broad: In addition to many industrial applications, it is very often used as a fuel gas in welding or as a calibration gas for gas measuring instruments and other devices for leak and gas detection.

More Info on Argon as Calibration Gas

The noble gas argon lives up to its name, which comes from the ancient Greek and means "the inert element." Like all other noble gases, argon is inert, which is why it is used in corresponding areas where this property is required – for example, as an inert gas in welding and in automatic fire extinguishing systems, as a protective gas in electrical engineering, in argon lasers in ophthalmology, or as a filling gas in incandescent lamps, insulating glass panes, and dry diving suits. But argon is also used as a test or calibration gas. In our atmosphere, the noble gas is present at nearly a one percent share, placing it third after nitrogen and oxygen. Argon is mainly obtained from the air, namely by fractional distillation of liquid air. Additionally, the gas is a byproduct in the synthesis of ammonia.

MORE INFO ABOUT CO2 TEST GAS

CO2 - one carbon atom and two oxygen atoms make up a molecule that is also known as carbon dioxide. As a greenhouse gas, it is an important component of our earth's atmosphere - although its share is decisive here. The natural greenhouse effect of CO2 ensures that part of the heat emitted by our planet into space is absorbed and radiated back to earth. And the higher the CO2 concentration in the air, the greater the impact of this greenhouse effect on global warming. In addition to its role as a greenhouse gas, carbon dioxide is used in many ways, especially in industry. In its gaseous state, it is used as a calibration gas or test gas for gas detectors, extinguishing agents or in welding technology, while in its solid state it is used as dry ice for cooling purposes.

Additional Information About Chlorine Test Gas (Cl2)

Chlorine (Cl2) derives from the Greek word chlorós, meaning "greenish-yellow." As the meaning suggests, it is also a greenish-yellow gas. The chemical symbol for chlorine is Cl, and in its elemental form as Cl2, occurrences of chlorine on this planet are very rare, due to its extreme reactivity. However, it is found in traces in the ozone layer and also in volcanic gases. Chlorine atoms are also present in the salts of salt deposits in chemically bound form. Moreover, chlorides (Cl-) are soluble in water and, accordingly, are present in large amounts in seawater. Chlorine in the form of chloride ions (Cl-) also occurs in the human body in table salt and is essential here for regulating water balance. Marine organisms such as sponges, algae, or seaweed are also capable of producing numerous chlorine-containing compounds.

Chlorine gas, on the other hand, is toxic to humans, animals, plants, and microorganisms such as bacteria. Not only does it easily destroy animal and plant tissue, but it also has a corrosive effect on human skin. Inhalation of chlorine gas can lead to chlorine gas poisoning: Concentrations as low as 1 ppm can impair lung function and cause eye irritation, while a chlorine gas concentration of 500 ppm can be fatal within minutes. Chlorine is used in various industries, including the food, beverage, and pharmaceutical industries, in paper and pulp production, electronics manufacturing, and also in wastewater treatment. The gas plays an important role in the production of antifreeze, brake fluids, fuel additives, pesticides, and plastics. To reduce their sulfur emissions, such as hydrogen sulfide or sulfur dioxide, refineries also inject chlorine directly into their stacks. One of the most important chemical reactions of chlorine is its combination with hydrogen to form hydrogen chloride, a key component in many industrial processes. This gas, better known as hydrochloric acid in aqueous solution, is a fundamental building block in the chemical industry and plays an important role in the production of PVC and many other plastics.

In environments where personnel are potentially exposed to the dangers of Cl2 gas – such as in storage tanks or near processing plants – air monitoring is mandatory, using chlorine gas, chlorine dioxide, and ozone systems. Chlorine gas warning devices continuously monitor the chlorine content in the chlorine gas room and possibly in additional technical rooms to detect chlorine gas leaks or outbreaks early. This immediately informs the personnel about technical defects to take appropriate measures. Chlorine gas warning devices can trigger the overhead sprinkler system in the affected chlorine gas room immediately upon a chlorine gas outbreak and send acoustic and optical warnings via external signal transmitters.

Chlorine test gas or calibration gas is therefore of crucial importance to guarantee the precision and performance of those gas warning systems, sensors, and measuring devices in these diverse application areas. Regular checks and calibrations with chlorine test gas ensure that safety-critical systems function properly and that employees can move in a safe environment where potential risks are identified in time.

More Information on helium(HE)

Helium (He) is the second smallest element in the periodic table. It has the lowest density after hydrogen and is indeed so light that it continuously escapes from the Earth's atmosphere into space, although it is also constantly replenished by solar winds. More precisely, helium is a colorless, odorless, tasteless, and non-toxic noble gas that occurs only in small amounts in the Earth's atmosphere. Helium is extracted from natural gas, in which it can be contained up to about seven percent.

Its unique properties, including low density, low reactivity, and high thermal conductivity, make helium an invaluable tool in a variety of applications. For example, it is used in gas chromatography as a carrier gas, in medical technology for cooling superconducting magnets in MRI machines, and in semiconductor manufacturing for cooling certain processes. In the industry, helium calibration gas is particularly used for leak detection and tightness testing. Thanks to its small molecule size, even the smallest leaks in systems can be detected. The use of helium calibration gas guarantees high accuracy and reliability in the monitoring and testing of plants and equipment operating under extreme conditions or subject to special requirements. Thus, helium calibration gas is crucial for ensuring the precision and performance of gas warning systems, sensors, and measuring devices in these diverse application areas.

Helium is non-flammable and non-reactive, hence it poses no danger to the environment or humans as such. However, usual precautions should be taken when handling helium calibration gas, as it can lead to suffocation in high concentrations. Therefore, always ensure adequate ventilation when dealing with helium calibration gas and avoid inhaling large amounts.

More Information on Toluene as a calibration gas

Toluene is an aromatic hydrocarbon with the structural formula C7H8 and is also known under the names methylbenzene, toluol, phenylmethane, or toluene. It is a colorless, volatile liquid with a characteristic odor and is also contained in gasoline, among other things. As mentioned before, it is often used as a gas for calibrating explosimeters or ex-meters, noting that in principle, any gas that the device sensor can detect can be used. In the context of fire brigades, toluene, along with methane, is very commonly used as a calibration gas - the latter especially because it is a major component of natural gas and is most often responsible for the risk of explosion in emergency situations. However, calibrating with methane has a downside: the concentration of other measured gases is significantly underestimated.

In general, the use of explosimeters aims to detect hydrocarbons. For this purpose, the calorimetric sensor is calibrated as sensitively as possible to signal a concentration of various substances that is rather too high than too low. Calibration with toluene has proven to be very effective for this, as it allows the gas detector to be adjusted approximately four to five times more sensitively than is the case with methane. It would be incorrect and unsafe to calibrate with methane since practically no gases exist that a calorimetric sensor would react to more sensitively than to methane.
