“…Gas chromatography (GC) is a commonly used technique for volatile separation in a mixture. The first modern GC was introduced by James and Martin in 1952, for the separation of volatile fatty acids (Bartle & Myers, 2002;Kolomnikov, Efremov, Tikhomirova, Sorokina, & Zolotov, 2018). GC experienced a rapid development in the first two decades and is a mature technique today (Ettre, 2002).…”

Gary A. Reineccius. I am very grateful for the privilege to have Gary as my advisor, not only in my research and study, but also in my life and career. His support, encouragement, wisdom, kindness and generosity have always influenced me positively, helping me release my fear of the unknown. My appreciation also extends to my laboratory colleagues in the flavor lab. Thanks to Vaidhyanathan Anantharamkrishnan, who provided me with every bit of guidance, assistance and support that I needed in my work. Thanks to Yara Benavides Paz, who served as my sensory panelist and provided me with useful advice in my research. Thanks to Katie Enzenauer and Bruna Barbon Paulo for their friendship and encouragement throughout my time in the lab as well as in my daily life. I also need to thank Jean-Paul Schirle-Keller, who helped me solve any analytical problems that I faced, making the experiments going well. I would also like to thank my defense committee members Dr. George A. Annor and Dr. Leonard F. Marquart for their value time and helpful guidance. Besides, I have to thank my former advisor Dr. Daniel J. O'Sullivan for helping me join the Food Science M.S. program here. ii Special thanks to Dr. David Marks and Ratan Chopra (Department of Plant and Microbial Biology), who shared their abundant knowledge and expertise on pennycress, and also provided pennycress sample for this research. My special thanks also expressed to Julie Kirihara (Center for Mass Spectrometry and Proteomics) for her patience, kindness and help in the mass spectrometry center. Most importantly, I owe this accomplishment to the endless love from my parents and my elder brother. I cannot image how can I reach this point without their support. iii DEDICATION This thesis is dedicated to my parents for always supporting me and encouraging me to do what I want to do. They gave me the courage to overcome the fear of "from having everything to having nothing" in a new environment. Thanks for them giving me the wings to fly further and higher.I also dedicated this thesis to my elder brother who always tries his best to protect me like a shield whenever problems try to reach me. Without my brother, I won't be the person I am today.

“…However, it was not until 1952 when chromatography took on its gas–solid version (James and Martin). In later years, equipment was developed that used both techniques, which eliminated the disadvantages that each one presented separately [15,16]. One of the main problems encountered in the analysis of VOCs was the impossibility of capturing these compounds, as they are very volatile.…”

Use of Electronic Noses for Diagnosis of Digestive and Respiratory Diseases through the Breath

2019

The increased occurrence of chronic diseases related to lifestyle or environmental conditions may have a detrimental effect on long-term health if not diagnosed and controlled in time. For this reason, it is important to develop new noninvasive early diagnosis equipment that allows improvement of the current diagnostic methods. This, in turn, has led to an exponential development of technology applied to the medical sector, such as the electronic nose. In addition, the appearance of this type of technology has allowed the possibility of studying diseases from another point of view, such as through breath analysis. This paper presents a bibliographic review of past and recent studies, selecting those investigations in which a patient population was studied with electronic nose technology, in order to identify potential applications of this technology in the detection of respiratory and digestive diseases through the analysis of volatile organic compounds present in the breath.

“…At present, multicomponent gas detection is mainly achieved by gas chromatography (GC), electrochemical sensors, and spectroscopy methods. GC 10 has high sensitivity and selectivity, but the device is bulky, expensive, and cumbersome maintenance is needed frequently. Besides, the gas will be consumed by the GC's detector with high sensitivity, for instance, flame ionization detector (FID) 11 and flame photometric detector (FPD).…”

Cavity-Enhanced Raman Spectroscopy for Detection of Trace Gaseous Impurities in Hydrogen for Fuel Cells

et al. 2023

View full text Add to dashboard Cite

Gaseous impurities contained in hydrogen (H2) profoundly affect the performance of hydrogen proton-exchange membrane fuel cells. We demonstrate the utility of cavity-enhanced Raman spectroscopy as a unique approach for detection of gaseous impurities. A dense-pattern multipass cavity which is composed of four spherical mirrors placed in a Z-shaped configuration is used to enhance the Raman signal by extending the laser–gas interaction length. A total of 85 spots are identified on the 2-inch-diameter front (or rear) mirror, which indicates that 510 beams exist in the cavity. Detection limits of the impurity gases, including oxygen (O2), nitrogen (N2), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), ammonia (NH3), and hydrogen sulfide (H2S), reach sub-ppm- and ppb-levels at a total pressure of 0.1 and 2.5 MPa, respectively. This satisfies the detection requirements according to the maximum allowable concentration for these gases. Our cavity-enhanced Raman spectroscopy (CERS) apparatus can simultaneously measure multiple gases with high sensitivity and selectivity with no sample destruction. It has excellent application prospects in gaseous impurity analysis for the quality assessment of gaseous energy.
