Geotech medical gas analyser gets glowing user report

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 newsletter on his experience with the new Geotech G210 N2O medical gas analyser.
 
In his summary Doyle concludes, “The G210 is small, light, and has good stability with improved linearity on all ranges. A key improvement has been the addition of data logging capability which facilitates testing of medical air plant and oxygen concentrators. The instrument has a fast re-charge with excellent battery life. The use of Li-Ion cells should end the problem of the memory effect that occurred with the NiCad cells employed in [the previous model] the FP99. The lower running costs of the G210 mean that anyone switching to this instrument from the FP99 will quickly recover their costs and make significant savings over the lifetime of the instrument … which will quickly pay for itself.”
 
Doyle cites the requested and included key features as; Improved stability and linearity with no external pods as all sensors are housed within the body of the instrument, simultaneous measurement of carbon dioxide and nitrous oxide, automatic data logging with user selectable time intervals for testing air plant, oxygen concentrators and ambient air in plant rooms.
He refers to; excellent longer battery life with a battery level indicator on the main display, USB connectivity for downloading data and for software upgrades for the analyser. He commends annual, rather than six monthly, calibration to minimize instrument downtime and lower calibration cost, and now ‘zero calibration’ for carbon dioxide, a feature missing from the earlier FP99 model. A big benefit is the smaller instrument size,
 
Up and running quickly
He said, “I found that I was able to use the basic features of the G210 within minutes of opening the box. With many more functions and options than the FP99, the menu structure is correspondingly deeper and more complex.
However, it is no more difficult to navigate than the average mobile phone menu tree and I was up and running very quickly without more than a few quick references to the detailed user manual.
 
“The instrument easy to calibrate and because of the improved linearity and stability it requires less-frequent calibration. This further improves running costs by reducing the use of expensive calibration gases. I find that the G210 gives good reproducibility in the readings obtained when alternating between different gases. The instrument also gives good reproducibility over time. For example, if I check the instrument against fresh ambient air and perform a similar check it maybe five or six hours later without re-calibrating in the interval, I usually find that the readings are almost unchanged.” See more and view full paper at:
