    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.

  3. Application Note: YSI Water Quality Monitoring Buoys Help Connecticut DOT Protect The Housatonic River
    12/27/2005
    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
  4. Application Note: YSI Real-Time Water Quality Monitoring And The IPSWATCH-EMPACT Program
    12/28/2005
    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).
  5. Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money
    12/1/2017

    Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

  6. Determination Of Hexanal In Foods Utilizing Dynamic Headspace
    4/9/2015

    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.

  7. The Basics: Testing RO Quality
    4/28/2014

    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.

  8. 1,2,3-Trichloropropane (1,2,3-TCP) Application Brief
    2/4/2016

    Previously TCP has been used as as a degreaser, paint remover, and cleaning agent. Currently TCP is utilized as a chemical intermediate in the manufacture of various organic chemicals.

  10. Application Note: Continuous Monitoring Of Drinking Water Provides Assurance Of Safety
    9/28/2005
    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
