TARGET OF THE PROJECT

Dilution of gasses for optical gas sensors

Description of the Application.

Gas sensing has a great influence in many areas across a wide range of applications, including ensuring safety via the detection of dangerous or flammable gases in environments, ranging from the domestic atmosphere to process and petrochemical industries, monitoring feedstocks and air pollutants, measuring the quality of gases mixture or quantity of key species.

Metal oxides are an emerging class of sensing materials that cover the entire range from metals to semiconductors and isolators whose sensitivity proprieties in the field of chemical sensing are known for more than five decades.

Considering electrochemical devices, initial drawbacks like low selectivity, signal drift, low response and sensitivity to humidity have pushed researchers to improve strategic characteristics of sensors by deeply studying the sensing mechanisms and optimizing crystal structure, morphology, and composition, but operational limits like inability to operate in harsh environments, for instance, high temperature, high pressure, or corrosive ambient is still a challenge.

To overcome these operational limits, using materials able to change optical proprieties (i.e. absorbance, transmittance, reflectance, refractive index, etc.), called optical gas sensors, instead of electronic proprieties; will offer higher thermal stability, good poison resistance, no electrical or magnetic fields dependence, in addition to fast response, high flexibility, and low-cost devices.

Benefits and Savings.

The optimization of the space in the lab reducing the bottle requirement with only one concentration used and diluted in line with the gas carrier, plus the Automation of the sensor’s analysis are great time-saving.

Various bottles collection with certified concentration and valve-cascade systems should be used instead of the MCQ Gas Blender 3000 Series with an important loss of money, time, and space.

▼MAIN BENEFITS

Cost and Space Savings.

Optimization of the space in the lab reducing the bottles requirement with only one at certified concentration, instead of many and diluted in-line with the gas carrier.

Successful Achievement.

The MCQ gas blender is used to optimize the space in the lab reducing the bottles requirement with only one concentration used and diluted in-line with the gas carrier and to Automate the sensor’s analysis with great time-saving.

Gas Blender vs Gas Cylinder.

The ability to mix gases on-demand is an incredibly powerful tool in the development of innovative gas sensor. And provides a level of flexibility that gas cylinders cannot provide.
