Air pollution monitoring: development of ammonia (NH3) dynamic reference gas mixtures at nanomoles per mole levels to improve the lack of traceability of measurements
Autor: Tatiana Macé, Maitane Iturrate-Garcia, Céline Pascale, Bernhard Niederhauser, Sophie Vaslin-Reimann, Christophe Sutour
Publikováno v: Atmospheric Measurement Techniques. 15:2703-2718
The measurement of ammonia (NH3) in ambient air is a sensitive and priority topic due to its impact on ecosystems. NH3 emissions have continuously increased over the last century in Europe because of intensive livestock practices and the enhanced use

Air pollution monitoring: Development of ammonia (NH3) dynamic reference gas mixtures at nmol/mol levels for improving the lack of traceability of measurements
Autor: Tatiana Macé, Maitane Iturrate-Garcia, Céline Pascale, Bernhard Niederhauser, Sophie Vaslin-Reimann, Christophe Sutour
The measurement of ammonia (NH3) in ambient air is a sensitive and priority topic due to its harmful effects on human health and ecosystems. NH3 emissions have continuously increased over the last century in Europe, because of intensive livestock pra

The importance of cylinder passivation for preparation and long-term stability of multicomponent monoterpene primary reference materials
Autor: Bernhard Niederhauser, Nicholas D. C. Allen, Céline Pascale, Paul J. Brewer, David R. Worton
Publikováno v: Atmospheric Measurement Techniques, Vol 11, Pp 6429-6438 (2018)
Monoterpenes play an important role in atmospheric chemistry due to their large anthropogenic and biogenic emission sources and high chemical reactivity. As a consequence, measurements are required to assess how changes in emissions of monoterpenes i

Towards an understanding of surface effects: testing of various materials in a small volume measurement chamber and its relevance for atmospheric trace gas analysis
Autor: Ece Satar, Peter Nyfeler, Céline Pascale, Bernhard Niederhauser, Markus Leuenberger
A critical issue for the long-term monitoring of atmospheric trace gases is precision and accuracy of the measurement systems employed. Both measuring and preparing reference gas mixtures for trace gases are challenging due to, for example, adsorptio

Compact devices for generation of reference trace VOC mixtures: a new concept in assuring quality at chemical and biochemical laboratories
Autor: Maricarmen Lecuna, Bernhard Niederhauser, Maria Paola Sassi, Guido Sassi, Céline Pascale, Alessia Demichelis
Publikováno v: Analytical and Bioanalytical Chemistry. 410:2619-2628
Volatile organic compounds (VOCs) in gas mixtures at trace level (nmol/mol) are routinely measured by chemical and biochemical laboratories as climate indicators, indoor air quality pollutants from building materials emissions, contaminants in food a
