Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS
6/21/2018
The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.

Ion Exchange Resins Reduce Pollution From Refineries
12/23/2013
A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

The Basics: Keeping Our Water Clean Requires Monitoring
4/30/2014
Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

Solution For Algae Blooms
12/17/2015
Harmsco® Filtration Products is pleased to offer a solution to the ever increasing blue-algae blooms in water sources. A multi-barrier approach is necessary to physically remove intact (algae and cyanobacteria) before they rupture in the treatment process and then remove extracellular cyanobacteria through adsorption.

Activated Carbon And Adsorption Of Trichloroethylene (TCE) And Tetrachloroethylene (PCE)
12/30/2013
Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.

Circuit Board Cleanliness Testing
10/29/2021
Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-28809 has been used as a guideline for control. Now a simple "on line" test for the relative measurement of ionic contamination has been developed.
