HPLC separation of alkylphosphonic acids on porous graphitic carbon sorbent
Hypercarb with water solution of formic acid as a mobile phase
Abstract
An approach to gradient HPLC separation of alkylphosphonic acids on
porous graphitic carbon sorbent Hypercarb with water solution of formic acid as
a mobile phase was proposed. Analytes were detected by quadrupole
mass-spectrometer. HPLC column was washed with water before the injection of
analytes, this procedure resulted in 3–4 fold increase of the retention times
of alkylphosphonic acids compared to literature data.
Key words: liquid chromtography (HPLC), mass spectrometry, porous
graphitic carbon Hypercarb, alkylphosphonic acids.
