What are the requirements for NDIR carbon dioxide sensor used in incubator?

Last Update Time: 2023-08-16 18:00:15

The design of the carbon dioxide incubator is to simulate the natural environment of the cells and to ensure that the conditions are constant. Although there are different types of incubators, most of them are designed to control CO2, relative humidity, temperature and pH at a constant level. New high-speed carbon dioxide sensors are now available, which allow designers to respond to and manage gas concentrations in near real-time as never before.

What is an incubator?

The microbial incubator is essentially a temperature-controllable oven that works in a strict biological range and is mainly used to cultivate and store microbial cultures. These incubators can be found in laboratories around the world and are essential equipment. Both medical and biological laboratories use incubators to provide the correct controlled environment for successful cultivation.

Why do we need to measure carbon dioxide?

The culture in the incubator requires very special environmental conditions. Normally, incubators allow users to monitor and adjust different conditions, such as temperature, relative humidity, and carbon dioxide levels, thereby controlling the pH of the culture medium to ensure and maintain optimal growth or storage conditions.

Cell growth is controlled by controlling the pH value, which is usually between 7.0 and 7.7. The chemical reaction in the medium can change the pH value. To counter these reactions, controlling the CO2 level helps to maintain a stable pH balance of the growth medium.

If there is not enough CO2 in the atmosphere, then the cell medium will release carbon dioxide and the substance will become more alkaline. Too high carbon dioxide concentration will cause more carbon dioxide gas to be absorbed by the mixture, resulting in acidity. Providing an environment in which carbon dioxide can be controlled helps to maintain the required carbon dioxide content in the growth medium and a stable pH value.

What are the requirements for carbon dioxide sensors?

The CO2 sensor used in the cell incubator should have good responsiveness, accuracy and stability. There will always be some uncertain changes in the incubator, which may have a negative impact on the culture. Therefore, it is important to understand when and to what extent the CO2 concentration changes and to be able to respond accordingly. Due to the high humidity environment, measures need to be taken to mitigate the effects of high humidity levels, especially during the disinfection process where condensation on the sensor can cause the sensor to report inaccurate results. With a fast carbon dioxide sensor to detect changes in carbon dioxide gas levels, the settings of the incubator can be adjusted in near real time, thereby reducing the chance of the incubator environment deviating from the standard.

NDIR carbon dioxide sensor

Adopt solid-state ultra-low power LED light source. This type of light source has many advantages, especially in low-power applications. Carbon dioxide gas is mid-infrared 425 micron light is strongly absorbed. GSS manufactures its own LEDs, which are specifically designed to emit light. Narrow band light of 25um.

GSS has designed a high-speed, high-response CO2 sensor series specifically for applications that require near real-time measurement of CO2 concentration.

 

Introduction of SprintIR-6S and ExplorIR-W

SprinTIR-6S and ExplorIR-W series sensors are a series of high-precision CO2 sensors designed to meet the needs of customers who need to quickly measure CO2 levels. The readings of SprinTIR-6S and ExplorIR-W sensors are 20 and 2 times per second respectively. The optical cavity of these two sensors is specially equipped with a flow adapter, which enables gas to flow through the sensor at a high speed, so that users can obtain high-speed measurement results.
