[10/24/16]   How We Smell, Measure and Eliminate Odors
An odor or fragrance, commonly referred to as a smell, is caused by one or more volatilized chemical
compounds generally at very low concentration, that humans or other animals perceive by the sense
of olfaction. Humans can perceive an odor even at the low part per billion (ppb) concentrations. Most
odor causing chemicals are perceived in the mid to high ppb range.
The sense of smell gives rise to the perception of odors, mediated by the olfactory nerve. The
olfactory receptor (OR) cells are neurons present in the olfactory epithelium, a small patch of tissue in
back of the nasal cavity. There are millions of olfactory receptor neurons that act as sensory signaling
cells. Each neuron has cilia in direct contact with air. The olfactory nerve is considered the smell
mediator; the axon connects the brain to the external air. Odorous molecules act as a chemical
stimulus. Molecules bind to receptor proteins extended from cilia, initiating an electric signal.
When the signal reaches a threshold, the neuron fires sending a signal traveling along the axon to the
olfactory bulb which is part of the limbic system of the brain. Interpretation of the smell begins,
relating the smell to past experiences and in relation to the substance(s) emitted. The olfactory bulb
acts as a relay station connecting the nose to the olfactory cortex in the brain. Olfactory information is
further processed and projected through a pathway to the central nervous system (CNS), which
controls emotions and behavior as well as basic thought processes.
Odor sensation usually depends on the concentration (number of molecules) available to the olfactory
receptors. A single odorant stimulus type is typically recognized by multiple receptors, and different
odorants are recognized by combinations of receptors, the patterns of neuron signals helping to
identify the smell. The olfactory system does not interpret a single compound, but instead the whole
odorous mix, not necessarily corresponding to concentration or intensity of any single constituent.
The widest range of odors consists of organic compounds, although some simple compounds not
containing carbon, such as hydrogen sulfide and ammonia, are also odorants. The perception of an
odor effect is a two-step process. First, there is the physiological part; the detection of stimuli by
receptors in the nose. The stimuli are processed by the region of the human brain which is
responsible for olfaction. Because of this, an objective and analytical measure of odor is impossible.
Odor feelings are very personal perceptions and individual reactions are related to gender, age, state
of health, and personal history.
Measurement of Odor Causing Chemicals
In some industries like pharmaceuticals, neutraceuticals, perfumery, cosmetics etc., an olefactometer
test is used to evaluate odor emanating from a product. You can also use olefactometry to determine
if a facility has an odor or a process gives off an odor. An olfactometer is an instrument used to detect
and measure ambient odor dilution. Olfactometers are used in conjunction with human subjects in
laboratory settings, most often in market research to quantify and qualify human olfaction. The panel
of human noses act as the sensors…the human’s perceptions is the measure of goodness.
A flow-olfactometer produces a constant heated and humidified flow of pure air. This air flow runs
continuously to the subject’s nose. For the length of the stimulus pulse the continuous air flow is
replaced by a bloc of odorized air. The new generations of dynamic dilution olfactometers quantify
odors using a panel and can allow different complementary techniques:
HowWeSmellMeasureEliminateOdor_20140904 Copyright © 2014, HGI Industries Incorporated Page 2
 odor concentration and odor threshold determination
 odor suprathreshold determination with comparison to a reference gas
 hedonic scale assessment to determine the degree of appreciation
 evaluation of the relative intensity of odors
 allow training and automatic evaluation of expert panels
The most recognized olfactometry standard is currently the EN13725 standard. Analyses performed
by olfactometers are often used in site diagnostics (multiple odor sources) performed with the goal of
establishing odor management plans.
In the air purification industry, the subjective elimination of odor is not commonly done using olefaction
testing. The elimination of odor is subjectively determined by the client in each unique installation.
How long it takes to “eliminate” an odor varies widely from client to client and as a function of the
problem (odor source), treatment volume, air circulation etc. If a more quantitative measure of “odor”
is required, an objective measurement of the reduction of volatile organic chemicals in air is done
using a variety of analytic methods (gas chromatograph-mass spectrometer, Summa canisters,
individual chemical detectors for ozone, ammonia etc.) that test samples of air collected during
operation of an air purification device as a function of treatment time in a given volume of space under
controlled conditions. Most of these analytical methods can measure levels of volatile organic
chemicals (VOCs) as low as a few parts per billion. HGI Industries (HGI) systems are able to reduce
a very broad range of VOC concentrations to the low ppb range with continuous use in a wide variety
of treatment environments and conditions. That level of VOCs generally eliminates the perception of
all odors.
HGI has published analytical data collected for its MDU™ Unit (two optics) by Columbia Analytical
Laboratories which shows the reduction in ambient VOCs to very low ppb levels after treatment with
its hydroxyl sanitizing system. HGI also provides various case studies where the elimination of
different types of odors was perceived to be satisfactory by the customer. Many of these odors like
smoke residue, meat rendering processing odors, animal odors, chemical odors etc. are very strong
and persistent and have proven to be very difficult to eliminate by other sanitizing and deodorizing
HGI’s systems work by generating hydroxyl free radicals (HO·) and related peroxy and oxy free
radicals from the irradiation of ambient oxygen and water vapor by ultraviolet energy in the same way
that the sun produces hydroxyl free radicals and their by-products outdoors. The sun’s ultraviolet
radiation produces natural, atmospheric hydroxyl radicals continuously. There are, on average, two
(2) million hydroxyls in each cubic centimeter of ambient outdoor air during daylight hours. They are
the main driving force behind the daytime reactions with hydrocarbons in the troposphere and
neutralize most natural and man-made pollutants including greenhouse gases like methane, hydrogen
sulfide, ammonia, ozone and various nitrogen oxide compounds.
Odorox® systems recreate the balance of nature indoors by generating “natural” hydroxyls in the same
concentrations that work exactly the same way as they do outdoor. They are powerful free radical
oxidizing agents that abstract a hydrogen atom from nearly all other chemicals. They are very
effective deodorizing agents because they target the locations in VOC molecules that cause odor.
The odor causing atoms are generally highly polarizing and activate the atoms nearby, making them
more susceptible to attack by free radicals.
