We deliver accurate measurements of nitrous oxide

Luke Purdie
Product Manager

As the global experts in gas analysis, Servomex delivers highly accurate measurements of nitrous oxide (N2O) in a range of applications. The SERVOPRO 4900 Multigas continuous emissions monitoring system (CEMS) gas analyzer delivers part-per-million (ppm) measurements of N2O for regulatory compliance, safety, and clean air. The SERVOTOUGH SpectraExact 2500 photometric analyzer measures nitrous oxide in a range of industrial processes, and is suitable for operation in hazardous areas. The SERVOPRO MultiExact 4100 and MultiExact 4200 multi-gas analyzers each provide ppm measurements of N2O for medical and industrial gas applications.

Why measure nitrous oxide?

Nitrous oxide (N2O) has a wide range of uses from medical gases to acting as a propellant. It has toxic properties, so emissions must be monitored by a nitrous oxide detector for safety purposes, as well as product quality in high-purity nitrous oxide gas production.

Common uses of nitrous oxide

Commonly known as ‘laughing gas’, nitrous oxide has been used as an anesthetic, pain relief, and anti-anxiety medication for more than 200 years. It is also used in the food industry to manufacture whipped cream and other food aerosols, and in vehicles as an engine accelerant. The production of high-purity nitrous oxide gas is, therefore, a key application in both the medical and industrial gas sectors, and requires accurate, reliable nitrous oxide measurement. While product purity is important, the possible toxic effects of long-term or high-concentration exposure to N2O also make nitrous oxide monitoring essential for safety.

How our nitrous oxide analyzers work to measure N2O

Servomex’s analyzers rely on the Gas Filter Correlation (GFC) sensing technology to accurately measure N2O concentrations. GFC is an advanced Infrared sensing technology that uses the property of gases to absorb unique light wavelengths to detect the concentration of a selected gas in a mixture. For N2O, it measures concentrations at ppm levels.

Our solutions for nitrous oxide gas analysis

Gas Filter Correlation (GFC) sensing technology is key to accurate nitric oxide detection. Servomex offers four nitrous oxide analyzer solutions for measurement using this technology. The 4900 Multigas, SERVOTOUGH SpectraExact 2500 , SERVOPRO MultiExact 4100, and SERVOPRO MultiExact 4200 all use GFC sensing technology to measure nitrous oxide at part-per-million (ppm) levels for a wide range of applications.
