(E)-2-Nonenal In Beer
Numerous compounds contribute to changes in beer flavor as it becomes stale. One of these compounds, (E)-2-nonenal, has been investigated as a major source of the papery/cardboard flavor that develops in aged beer.
Water Determination In Liquefied Petroleum Gas Using GC BID And Ionic Liquid Column Watercol™
Water in petrochemical feedstocks can cause problems for processors. Freezing of pipe lines and valves and poisoning of expensive catalysts are just a few examples.
Application Note: YSI Water Quality Monitoring Buoys Help Connecticut DOT Protect The Housatonic River
When replacement of the Sikorski Bridge spanning the
Housatonic River was authorized, Paul Corrente and the
Connecticut Department of Transportation (CT-DOT) set
about the design and development of a water quality monitoring
program to monitor the contractor’s in-water activities to
insure full protection of
the river from perturbation
Application Note: YSI Real-Time Water Quality Monitoring And The IPSWATCH-EMPACT Program
The Ipswich and Parker Rivers watersheds lie only a short
distance north of Boston, MA. The first settlements in these
watersheds began in the early 1600s. Since that time, residents
have relied heavily on the natural resources of the Parker and
Ipswich Rivers, their coastal estuaries and Plum Island Sound,
which is known as the Great Marsh. This ecosystem has been
designated and protected by the Commonwealth of Massachusetts
as an Area of Critical Environmental Concern (ACEC).

Determination Of Hexanal In Foods Utilizing Dynamic Headspace
Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.
The Basics: Testing RO Quality
Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached.
1,2,3-Trichloropropane (1,2,3-TCP) Application Brief

Application Note: Continuous Monitoring Of Drinking Water Provides Assurance Of Safety
A water utility in Ohio wanted to learn more about the variability of water quality parameters such as pH, ORP, turbidity, and chlorine. Previously, most of these parameters had been measured by spot sampling protocols with only a few
measurements during a daily period. In order to more accurately assess the water variability, the utility used a YSI 6920DW Drinking Water Multiprobe
