You can use the Cogent Bidentate C18™ column in reversed phase (RP) with a high water content method. According to a 2014 third-party research article, if the analysis is done by reversed phase an ion pair agent is recommended to increase retention and reduce peak tailing. Here, 8 mM sodium sulfate was used in a pH 4.3 phosphate buffer mobile phase. Cogent™ columns work well with ion pair agents and will not be degraded. Also, the Bidentate C18™ is more hydrophobic than other columns on the market due to the Cogent TYPE-C Silica™ surface. Therefore you may obtain higher retention for this highly polar analyte.
As for detection methods, it was reported that direct detection can be achieved by the addition of a KOH solution to the sample. In this case, a narrow absorbance band was observed with λmax at 200 nm. Indirect detection could also be used; in this case, you add a UV absorbing compound in the mobile phase and obtain a negative peak.
If you try the method by ANP, we suggest the Cogent Diamond Hydride™ column. You will want to omit the ion pair agent in this case and use a high percent of acetonitrile in the mobile phase to obtain retention.
