polyethylene glycol compounds (PEGs) that occur in flowback water samples from
hydraulic fracturing. The Kendrick Mass Defect was applied to differentiate the various
adducts within a suite of PEGs. A database of the accurate masses along with
their retention times by UHPLC has been designed to enable rapid and accurate
analysis of either groundwater or flowback samples from hydraulic fracturing.
Forty PEGs and their various adducts and multiply-charged ions can be identified in
less than 2 minutes of computer time.详细>
