Analysis of Fracking Flowback Water from Marcellus Shale
Product News Dec 13, 2013
Thermo Fisher Scientific has announced a new technical note TN 139: Determination of Anions in Fracking Flowback Water From the Marcellus Shale Using Automated Dilution and Ion Chromatography which demonstrates the use of in-line conductivity measurement to trigger automated dilution prior to separation and quantification of inorganic ions and organic acids in Marcellus Shale fracking flowback samples using ion chromatography.
The high levels of dissolved salts leached from bedrock are a challenge to analyzing fracking flowback solutions. Injection of high ionic strength solutions can exceed the capacity of columns used in ion chromatography, resulting in poor chromatography.
Hence, the use of in-line conductivity measurement to trigger automated dilution is a viable technique for the need to load less sample.
