N2O sensor for the detection of nitrous oxide

Nitrous oxide can be found in many industrial processes: It is used in medical technology to anaesthetise patients or in the food industry to foam milk products. To achieve the desired result, the correct mixing ratio is crucial. Furthermore, leakages can affect people's perception and concentration and thus endanger occupational safety. Nitrous oxide is also used in semiconductor manufacturing as a reaction gas for coating circuit board surfaces.  

N2O sensors of the FLOWEVO series from smartGAS are ideally suited for this task: they work on the basis of non-dispersive infrared absorption (NDIR) and therefore detect even the lowest concentrations of nitrous oxide. The sensors are available for the measuring range of 500 ppm.

Laughing gas as a sedative

In medicine, nitrous oxide is used as an analgesic (anti-pain) gas for anaesthesia purposes or in a fixed combination of 50% nitrous oxide and 50% oxygen (MEOPA) for pain treatment for short, moderately painful surgical procedures. It has also become widely used as so-called titratable nitrous oxide sedation in dentistry. It is an anaesthetic that has been used regularly since 1844 and has relatively few side effects.

 

N2O in the food industry

In food technology, nitrous oxide is used as an approved food additive (E 942) due to its good fat solubility under pressure as a propellant gas, preferably for dairy products, for example to foam (instead of whip) whipped cream or to make fresh cheese airy.

Nitrous oxide use in the semiconductor industry

In semiconductor manufacturing, nitrous oxide is used as a protective atmosphere to improve the quality of the products. In contrast to the use of oxygen, the silicon surface under nitrous oxide is more noble and leads to better quality.
