Kohlenstoffmonoxid – Wikipedia

Kohlenstoffmonoxid (fachsprachlich Kohlenstoffmonooxid, gebräuchlich Kohlenmonoxid) ist eine chemische Verbindung aus Kohlenstoff und Sauerstoff mit der Summenformel CO. Kohlenstoffmonoxid ist ein farb-, geruch- und geschmackloses sowie toxisches Gas. Es entsteht unter anderem bei der unvollständigen Verbrennung von kohlenstoffhaltigen Stoffen bei unzureichender Sauerstoffzufuhr.

Frequently Asked Questions - Gas Sensor Technology

Frequently Asked Questions. Q: What is the difference between infrared and electrochemical gas sensors? A: The main difference is in the measurement method. In electrochemical sensors, the sensitive element remains in direct contact with the gas and a chemical reaction occurs. This causes the sensor element to be contaminated by the reaction products which leads to loss of sensitivity ...

Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs ...

CO sensors can become saturated with target gas CO. If enough CO enters the sensor beyond maximum range (that listed in the instruction manual), the sensor is unlikely to be able to process all applied gas. When this scenario occurs, the electrolyte becomes saturated. A saturated sensor will continue to show high gas readings until the gas can be processed from the electrolyte. If saturation ...

Operating principle ‐Electrochemical-type gas sensor

The oxidation potential of CO gas (as expressed in Equation 1) is lower than the oxidation potential of the electrode(2H+ + 2e-⇔ H 2), oxidation of CO has less noble potential than deoxidization. Since this reaction occurs easily, no external energy is needed to stimulate the sensor’s chemical reaction, unlike with three-electrode type sensors. As a result, this two-electrode type ...

Carbon monoxide awareness - Gas safety - HSE

Carbon monoxide (CO) is a colourless, odourless, tasteless, poisonous gas produced by incomplete burning of carbon-based fuels, including gas, oil, wood and coal. Carbon-based fuels are safe to use. It is only when the fuel does not burn properly that excess CO is produced, which is poisonous. When CO enters the body, it prevents the blood from bringing oxygen to cells, tissues, and organs.

Common Testing Questions - Testo, Inc

Electrochemical sensors are devices that measure flue gas constituents (O2, CO, NO, NO2, SO2, H2S) through the principle of ion selective potentiometry The sensor contain a electrolytic matrix that is designed for a specific gas to be detected. Two or three electrodes (again gas specific) are placed in this matrix and an electrical field is applied. Flue gas enters the sensor and chemically ...

CO and CO2 – What’s the difference? |

The molecular weight of CO is , where the molecular weight of CO2 is This means that the CO2 gas is much more dense than CO. CO2 will collect near floor level while CO will collect closer to the ceiling. OSHA lists danger levels for CO beginning at 35 ppm, and for CO2 starting at a 5,000 ppm time-weighted average.
