The need for multicomponent gas standards for breath biomarker analysis

July 7, 2022
Author(s)
Kavita Jeerage, Jennifer Berry, Jacolin Murray, Cassie Goodman, Paulina Piotrowski, Christina Jones, Christina Cecelski, Jennifer Carney, Katrice Lippa, Tara Lovestead
Exhaled breath is a non-invasive, information-rich matrix with the potential to diagnose or monitor disease, including infectious disease. Despite significant effort dedicated to biomarker identification in case control studies, very few breath tests are

Rhoderick, Antonio Possolo, Jennifer Carney, Miroslav Vokoun, Jitka Privoznikova, Sangil Lee, Ji Hwan Kang, Yong Doo Kim, Dal Ho Kim, Tatiana Mace, Christophe Sutour, Celine Pascale, Napo Ntsasa, James Tshilongo, Mudalo Jozela, Nompumelelo Leshabane, Goitsemang Lekoto, David Worton, Paul Brewer, Fred Farrow-Dunn, Sergi Moreno, Klaus Wirtz, Volker Stummer, L.A. Konopelko, A.V. Kolobova, Y.A. Kustikov, A.Y. Klimov, O.V. Efremova, Janneke van Wijk, Adriaan van der Veen
The CCQM-K10.2018 comparison aimed to evaluate the capabilities of national metrology institutes (NMIs) to prepare and/or value assign primary reference mixtures containing benzene, toluene, ethylbenzene, p-xylene, m-xylene and o-xylene (subsequently

Certification of NIST Gas Mixture Standard Reference Materials

February 10, 2022
Author(s)
Christina Cecelski, Kimberly Harris, Cassie Goodman, William A. Kimes, Philip Liu, Walter R. Miller Jr., Jennifer Carney
The Gas Sensing Metrology Group at NIST provides accurate, stable gaseous standards for use in various types of emissions testing and environmental monitoring. The group develops and maintains the highest level of primary gas standards, which provide

The National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards, was established by the U.S. Congress in 1901 and charged with establishing a measurement foundation to facilitate U.S. and international commerce. NIST

Environmental Protection Agency Blind Audit 2018

May 17, 2021
Author(s)
Christina Cecelski, Cassie Goodman, Jennifer Carney
The U.S. Environmental Protection Agency (EPA) conducted a blind audit of EPA protocol calibration gas mixtures produced by specialty gas manufactures. The objective was to determine the amount-of-substance fraction (concentration) of the analytes in the

Comparison of primary laser spectroscopy and mass spectrometry methods for measuring mass concentration of gaseous elemental mercury

December 10, 2020
Author(s)
Abneesh Srivastava, Stephen E. Long, James E. Norris, Colleen E. Bryan Sallee, Jennifer Carney, Joseph Hodges
We present a direct comparison between two independent methods for the measurement of gaseous elemental mercury (GEM) mass concentration: isotope dilution cold-vapor inductively coupled plasma mass spectrometry (ID-CV-ICP-MS) and laser absorption
