Bisphenol A, octylphenols and nonylphenols in fish muscle determined by LC/ESI-MS/MS after affinity chromatography clean up.

An analytical method is applied to simultaneously determine bisphenol A, 4-octylphenol, 4--octylphenol, 4-nonylphenol and -nonylphenol in fish muscle. The method consisted of a cleanup on molecularly imprinted polymers cartridges (MIPs) followed by liquid chromatography coupled to a tandem mass spectrometer. The method is rapid, specific, reliable and very sensitive, allowing for quantification down to 0.

BPA, BPB, BPF, BADGE and BFDGE in canned beers from the Italian market.

A survey of BPA, BPB, BPF, BADGE and BFDGE contamination in canned beers from the Italian market is reported. An analytical method for the determination of these five bisphenols down to 0.5 ng mL using UPLC with fluorescence detection was developed and validated.

Determination of BPA, BPB, BPF, BADGE and BFDGE in canned energy drinks by molecularly imprinted polymer cleaning up and UPLC with fluorescence detection.

A new method for simultaneous determination of five bisphenols in canned energy drinks by UPLC with fluorescence detection, after clean up on molecularly imprinted polymers, is herein described. The method was validated at two concentration levels, calculating trueness, repeatability and within-laboratory reproducibility, specificity, linearity of detector response, the limits of quantifications and the limits of detection for each bisphenol. The method is specific, reliable and very sensitive, allowing for determination of bisphenol F diglycidyl ether (BFDGE), bisphenol A (BPA), bisphenol B (BPB), bisphenol F (BPF) and bisphenol A diglycidyl ether (BADGE) down to 0.
