CO2 Incubator Troubleshooting 101: Gas Consumption – cell ...

· CO2 gas escapes primarily when the CO2 incubator door is opened. Prolonged door opening makes it hard for the CO2 incubator to return to its optimal CO2 condition and will definitely cause increased gas consumption. 5. Mind the chamber’s capacity. Do not overload. Overloading the chamber will also cost you increased gas consumption to compensate for all those living cells that …

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%. (Not GfG sensors, of course!) Sometimes the cross …

Carbon Monoxide Poisoning

Carbon monoxide (CO) is a poisonous, colorless, odorless and tasteless gas. Although it has no detectable odor, CO is often mixed with other gases that do have an odor. So, you can inhale carbon monoxide right along with gases that you can smell and not even know that CO is present. CO is a common industrial hazard resulting from the incomplete burning of material containing carbon such as ...

Lambda sensor testing and troubleshooting | HELLA

The first lambda sensors were not heated, and so had to be installed near the engine in order to reach their operating temperature as quickly as possible. Nowadays, lambda sensors are equipped with sensor heating. This means that the probes can also be installed away from the engine. Advantage: They are no longer exposed to the high thermal load. The sensor heating enables them to reach their ...
