“…During the ANITA I mission, strong artifacts were observed in many spectra. In the "wrong" spectral region, these artifacts appear as signals similar to CO2 and H2O, that is why they are called "ghosts" [9]. Fig.5 shows spectral ghosts after eliminating all real features from the spectrum.…”

h i g h l i g h t sThe influence of oxidation modification on the properties of CDC was studied. The relationship between the properties and adsorption performance was studied. The acidic oxygen-containing groups in CDC increase the adsorption capacities. DFT predicts the role of acidic oxygen-containing groups for adsorption. a r t i c l e i n f o t r a c tThe adsorption of acetaldehyde over carbide-derived carbon (CDC) modified with nitric acid, hydrogen peroxide, or air was investigated. The physicochemical properties of the original and modified CDCs were characterized by N 2 adsorption, Fourier transform infrared spectrometer, temperature programmed desorption and X-ray photoelectron spectroscopy. It was observed that the oxidation modification, especially the nitric acid treatment, could significantly enhance the adsorption performance of CDC for acetaldehyde. The increase of acidic oxygen-containing groups like carboxylic acids and anhydrides in the modified CDCs results in the increase of adsorption performance. The density functional theory calculations and in situ Diffuse Reflectance Infrared Fourier Transform Spectroscopy show that these acidic oxygen-containing groups display strong hydrogen bonding interactions with acetaldehyde molecule, leading to the enhanced adsorption performance.Ó 2015 Published by Elsevier B.V.

“…Previous work in testing air quality instruments on ISS has included the Volatile Organics Analyzer (VOA) from NASA and the Analysing Interferometer for Ambient Air {ANITA) from the European Space Agency [1][2][3]. VOA measurements are taken up to a few times a day, and so provide a snapshot of the presenc(l (or absence) of some forty chemical species, but does not give insight into air constituent changes lasting less than several hours.…”

NASA . Jet Propulsion Lab, CA, 91011The atmospheric composition inside spacecraft is dynamic due to changes in crew metabolism and payload operations. A portable FTIR gas analyzer was used to monitor the atmospheric composition of four modules (Core lab, Veggie Plant Atriun, Hygiene module, and Xhab loft) within the Deep Space Habitat '(DSH) during the Mission Operations Test (MOT) conducted at the Johnson Space Center. The FTIR was either physically relocated to a new location or the plumbing was changed so that a different location was monitored. An application composed of 20 gases was used and the FTIR was zeroed using N2 gas every time it was relocated. The · procedures developed for operating the FTIR were successful as all data was collected and the FTIR worked during the entire MOT mission. Not all the 20 gases in the application sampled were detected and it was possible to measure dynamic VOC concentrations in each DSH location.
