The ability to accurately monitor and control the carbon dioxide (CO<sub>2</sub>) levels in a cell culture incubator is a critical factor in maintaining optimal culture conditions. With the advent of innovative sensor technologies, the ability to mimic mammalian physiological pH has become increasingly sophisticated and efficient.</p> <p>Traditional infrared (IR) CO<sub>2</sub> sensors are widely used in the industry. However, they come with their set of challenges. The incandescent light sources that are commonly used in these sensors tend to burn out over time, leading to inaccurate readings. Furthermore, dust and dirt can accumulate on the sensor surfaces, causing interference and apparent changes in CO<sub>2</sub> concentration. Most of these sensors are positioned outside the incubation chamber, which can result in a delayed response to changes within the chamber.</p> <p>In response to these challenges, advancements in sensor technology have led to the development of more robust and durable CO<sub>2</sub> sensors, such as the <a href="https://www.thermofisher.com/us/en/home/life-science/lab-equipment/co2-incubators/features.html#precision-sensors">precision sensors found in various Thermo Scientific CO2 Incubators</a>. These next-generation sensors utilize silicon micro-electrical mechanical systems (MEMS) emitters, which are not only more robust but also have a significantly longer lifespan than their incandescent counterparts. This translates into substantial cost savings due to reduced calibration and replacement needs.</p> <p>These advanced sensors are <a href="https://assets.thermofisher.com/TFS-Assets/LED/Specification-Sheets/CO2-SensorLocation-SMARTNOTE-EN.pdf">positioned in the incubation chamber</a> to react to the same conditions that the cells experience. This positioning leads to more accurate and immediate measurements. Moreover, the design of these sensors allows them to withstand multiple high-temperature sterilization cycles, significantly reducing the risk of contamination.</p> <p>In terms of operation, these sensors employ a single beam with dual wavelengths and a micromachined Fabry-Perot Interferometer (FPI) filter in front of a single detector. This unique design compensates for changes in the IR light intensity and the accumulation of dirt and dust, without the need for a second detector.</p> <p>In tests, these advanced CO<sub>2</sub> sensors have shown exceptional stability over time and under different CO<sub>2</sub> concentrations. They remain well within prescribed specifications, even after withstanding numerous high-temperature sterilization cycles.</p> <p>In conclusion, the advancements in infrared CO<sub>2</sub> sensor technology offer a highly accurate, stable, and durable solution for CO<sub>2</sub> monitoring in cell culture incubators.
