Characterization of Fourier transform infrared, cavity ring-down spectroscopy, and optical feedback cavity-enhanced absorption spectroscopy instruments for the analysis of ammonia in biogas and biomethane

Culleton, Lucy P.; di Meane, Elena Amico; Ward, Michael K. M.; Ferracci, Valerio; Persijn, Stefan; Holmqvist, Albin; Arrhenius, Karine; Murugan, Arul; Brewer, Paul J. (American Chemical Society, 2022-10-27)

Novel traceable analytical methods and reference gas standards were developed for the detection of trace-level ammonia in biogas and biomethane. This work focused on an ammonia amount fraction at an upper limit level of ...
Investigation of cylinder pre-treatments for the stability of ammonia gas reference materials

di Meane, Elena Amico; Brown, Richard J. C.; Brewer, Paul J.; Ferracci, Valerio; van Wijk, Janneke I. T. (Springer, 2022-07-14)

This report describes work to evaluate the performance of different commercial and proprietary cylinder treatments in improving the stability of ammonia reference materials in high pressure cylinders. Gas mixtures of 100 ...
Production and stability of low amount fraction of formaldehyde in hydrogen gas standards

Bacquart, Thomas; Perkins, Mark; Ferracci, Valerio; Martin, Nicholas A.; Resner, Kate; Ward, Michael K. M.; Cassidy, Nathan; Hook, Joshua B.; Brewer, Paul J.; Irvine, John T. C.; Connor, Paul A.; Murugan, Arul (Elsevier, 2018-03-03)

Formaldehyde is an intermediate of the steam methane reforming process for hydrogen production. According to International Standard ISO 14687-2 the amount fraction level of formaldehyde present in hydrogen supplied to fuel ...
