Atmospheric Pressure Corrections on Interscan Instruments When a gas concentration is measured or reported, we may talk in terms of ppm, but in reality we are measuring the partial pressure of the gas. (Refer to Dalton'[...more]
Within sterile processing departments, the predominant modality for ethylene oxide sterilization is the sealed EtO cartridge approach, as sold by 3M. In its Product Profile on the Steri-Gas™ EO cartridges, 3M puts forth these reco[...more]
In recent months, we have seen certain people touting systems using gas chromatography (provided with a photo-ionization detector) for area monitoring of ethylene oxide in Supply, Processing, and Distribution (SPD) departments. [S[...more]
As if it weren't bad enough that clueless environmental authorities try to impose their ignorance on the field by using so-called "metric" units of gas concentration, another trap may be lurking for you. Everyone around the world[...more]
What are the calibration techniques available for quantifying a gas? Suggest a few methods for quantifying ammonia in particular.
See our article entitled "Calibration Basics," which covers calibration techniques. For ammonia, we would recommend permeation tubes.[...more]
