N2O when combined with O2 in 50% / 50% ratio is commonly known as ‘laughing gas’ and has a wide variety of uses from helping dealing with labour pains to numbing your mouth for dental surgery.  The gases are piped round hospitals to critical areas such as theatres and intensive care wards, these outlets need regular checking to ensure the gas quality is maintained and there are no contaminants present.  Measuring with infrared technology allows you to get the best accuracy and allows easy user calibration.

G210 verifies piped medical gases

Report in the Medical Gas Association newsletter Consultation with medical gas quality controllers (QCs) to optimise specification has lead to, “A major improvement in portable instrumentation for the analysis of medical gases,” according to Ed Doyle QC (MGPS). He reported in the August 2010 issue of the Medical Gas Association (www.mga.org.uk) newsletter on his experience…

G200 detects N2O leak in sedation equipment at dental surgery

About the customer Dental practice, Dover, England Challenge the customer faced A dental engineer was sent to investigate N2O problems at the dental surgery after complaints from staff about the effects of the gas.  Previous passive monitoring in the surgery had indicated a time weighted average (TWA) of N2O at 90ppm, and a suspected leak…

An analyser is only as accurate at the moment of calibration.  Following this point, electrochemical cells / sensors will begin to degrade and this can be increased through heavy use.  However alongside ensuring regular servicing, we recommend you perform regular user calibrations and checks.  By using span gases similar in composition to your typical N2O values, the accuracy of the N2O channel can not only be maintained, but can be improved for your specific application. Always ensure that your analyser is purged with fresh air between readings and at the end of the day’s readings to ensure no residual gas remains in the analyser.
