Quantifying Mosquito Attraction Behavior Using Olfactometry
Cold Spring Harbor Protocols, 2023When blood feeding from human hosts, female mosquitoes can transmit life-threatening pathogens to humans, including dengue virus, chikungunya virus, and Zika virus. Olfaction is the primary sense mosquitoes use to locate and differentiate hosts and studying it can lead to new strategies to reduce the risk of disease.

Gas Chromatography/Olfactometry
Current Protocols in Food Analytical Chemistry, 2003AbstractVolatile odorants can be analyzed by gas chromatography/olfactometry (GC/O), a collection of techniques that range from simple modifications of GC equipment to elaborate commercial GC‐olfactometers and protocols. This unit describes the direct column sniffing, dilution analysis, and time intensity protocols most commonly used in the food ...

A historical review of olfactometry
L’Année psychologique, 2021Cet article passe en revue l’histoire de l’olfactométrie du xix e siècle à nos jours. L’olfactomètre a été inventé en 1888 par le physiologiste hollandais Hendrik Zwaardemaker (1857-1930), dont nous décrivons ici en détail les travaux. À partir de cette date, son instrument fut utilisé par de nombreux physiologistes et psychologues européens et ...

Electro-Olfactogram (EOG) in Olfactometry
Auris Nasus Larynx, 1989The electro-olfactogram (EOG) is a potential originated in olfactory epithelium evoked by odorous stimulation, which has been demonstrated and termed by Ottoson (1959). In order to ascertain the clinical application of EOG, we attempted to record similar potentials in human subjects.

Importance of Unilateral Examination in Olfactometry
Auris Nasus Larynx, 1988Hyposmia, the decreased sense of smell, and anosmia, the loss of sense of smell, may be unilateral or bilateral. If the olfactory acuity examined by means of bilateral test is normal, olfactory disorders are not found; unilateral examination is therefore necessary for definite evaluation of olfactory acuity. As evidence, 7 cases out of 94 patients with

Gas chromatography–olfactometry in food flavour analysis
Journal of Chromatography A, 2008The application of gas chromatography-olfactometry (GC-O) in food flavour analysis represents to be a valuable technique to characterise odour-active, as well as character impact compounds, responsible for the characterizing odour of a food sample. The present article briefly reviews the use of GC-O in the flavour investigation of dairy products (milk ...

A brief history of olfaction and olfactometry
The Journal of Laryngology & Otology, 2008AbstractThe sense of smell has been a cause for speculation and fascination over the centuries. An appreciation of odours has been deeply rooted in many cultures, including ancient civilisations such as the Egyptians. The level of understanding of the anatomy and physiology of olfaction which our ancestors had was slight, and much remains to be ...

Basics, Methods and Indications for Objective Olfactometry
Laryngo-Rhino-Otologie, 2002Basics, Methods and Indications for Objective Olfactometry. Olfactory disorders are receiving more widespread attention due to their large impact on quality of life. Olfaction may be evaluated with psychophysical methods that use such tools as Sniffn' Sticks® or the UPSIT® and with objective olfactometry.

Odours metrology and industrial olfactometry
1994Publisher Summary This chapter focuses on odors metrology and industrial olfactometry. Olfactometry is a method proposed to the industry to solve its odors and air pollution problems. The determination of the dilution flow at the perception threshold of a gaseous sample allows establishing odor concentrations free from any subjective limitation. This
