Analysis of Geosmin and 2-Methylisoborneol Utilizing the Stratum PTC and Aquatek 70
Abstract Geosmin and 2-Methylisoborneol are organic compounds that have a distinct scent. These compounds also have an extremely low odor detection threshold and because of this, many drinking water laboratories require detection levels of below 10ppt. This application note investigates the detection of Geosmin and 2-Methylisoborneol at a one part per trillion (ppt) level utilizing Purge and Trap ...

What’s Good For The Goose …
We’re not just a software company. We’re a quality company; and that means we love processes. When we say “processes,” some people roll their eyes. But it’s really a matter of perspective. Some people see processes as restrictive. We see them as an agreed upon way to get the desired result, a way to ensure the desired result. I see them as my pathway to ...

Fire and Smoke residual air contaminants testing
Only recently has the ability to accurately test for the residuals of fires become possible. There have long been concerns for the health of firefighters from fire emissions. Also, occupants of buildings and even neighborhoods affected by fire and the residuals of those fires are often greatly concerned about contaminants that exist for days, weeks, months, after the fire has been extinguished. ...

Occurrence of earthy and musty odor compounds (geosmin, 2-methylisoborneol and 2,4,6-trichloroanisole) in biologically treated wastewater
The concentrations of earthy and musty odor compounds (2-methylisoborneol (2-MIB), geosmin and 2,4,6-trichloroanisole (TCA)) in treated wastewater were measured. Concentrations of 2,4,6-TCA (4.3–37.7 ng/L) and geosmin (3.7–42.2 ng/L) higher than their odor thresholds were detected for effluents from large-scale treatment plants. The effluent from a small-scale wastewater plant ...

Use of biocatalysts to reduce hydrogen sulfide emissions from lagoons and landfills
Emission of odors from ponds and lagoons occurs due to aerobic and anaerobic decomposition of organic solids to release hydrogen sulfide, ammonia, and other organic by-products. Aerobic biodegradation occurs near the water-air interface, where diffusion of oxygen occurs, while anaerobic degradation prevails mainly near the bottom of the pond or lagoon, where there is low or no dissolved oxygen ...

Case Study: Cost-effective odor control
The aromas from savory flavors are detectable even at low concentrations, and pose special challenges for companies who manufacture or use them. Mastertaste, a Division of Kerry Group plc, is a leader in the development and production of savory flavors and blended seasonings. As part of a plant expansion, Mastertaste needed a system to eliminate odors from savory notes and essential oils to a ...

How to analyze H2S, all Mercaptans, THT as well as total sulfur for monitoring natural gas or gaseous fuels in metering station?
Natural gas is colourless and odourless in its most pure form. When extracted, it can contain sulfur compounds such as H2S and Mercaptans that when in the presence of moisture can produce sulfuric acid that can degrade the pipeline. So for reasons of public safety as well as pipeline integrity, there is a need to measure and control precisely the level of odorant species in natural gas : ...

Variations of odorous VOCs detected by different assessors via gas chromatography coupled with mass spectrometry and olfactory detection port (ODP) system
Odorous volatile organic compounds (VOCs) were analysed via a thermal desorption gas chromatograph coupled with a mass spectrometer and olfactory detection port (TD-GC-MS/ODP) to characterize odour emissions from a wastewater treatment plant (WWTP). Three trained ODP assessors, screened according to the European dynamic olfactometry standard (EN: 13725), were used for the olfactory analysis. ...
