9252053 | Sorensen LK, Rasmussen BM, Boison JO, Keng L: Simultaneous determination of six penicillins in cows' raw milk by a multiresidue high-performance liquid chromatographic method. J Chromatogr B Biomed Sci Appl. 1997 Jul 4;694(2):383-91. A high-performance liquid chromatographic method based on C18 solid-phase extraction and ultraviolet detection at 323 nm of analytes derivatized with benzoic anhydride and 1,2,4-triazole mercuric chloride solution was developed for the simultaneous determination of amoxicillin, penicillin G (benzylpenicillin), ampicillin, oxacillin, cloxacillin and dicloxacillin residues in raw milk. |

After protein precipitation with tungstate, samples are applied to a C18 solid-phase extraction cartridge, from which penicillin is eluted, derivatized with 1,2,4-triazole-mercuric chloride solution, and analyzed by isocratic liquid chromatography (LC) on a C18 column with UV detection at 325 nm. |

J Chromatogr. 1992 May 8;576(2):315-20. The assay utilizes a simple extraction of penicillin G from plasma (with a known amount of penicillin V added as internal standard) with water, dilute sulphuric acid and tungstate solutions, followed by concentration on a conditioned C18 solid-phase extraction column. After elution with 500 microliters of elution solution, the penicillins are derivatized with 500 microliters of 1,2,4-triazole-mercuric chloride solution at 65 degrees C for 30 min. |

Operational measurements of the speciation of dissolved Hg (II) using Sep-Pak C18 columns indicate a reduction in the proportion of hydrophobic (C18-retained) dissolved Hg (II) complexes with increasing salinity, both in the presence and absence of suspended particles. |

The penicillins are extracted from bovine tissues with 0.1 M buffer (pH 8.5), cleaned up on a t-C18 Sep-Pak cartridge, and eluted with 2 mL acetonitrile. After the acetonitrile in the eluate is evaporated to dryness, the residue is dissolved in 200 microL (40 + 60, v/v) acetonitrile- buffer (pH 6.5) and derivatized with acetic anhydride and mercuric chloride in the presence of 1,2,4-triazole at 65 degrees C for 30 min. |

This method involves separation of penicillins on a C18 column, postcolumn reaction with and mercury (II) introduced into the main flow stream using sulfonated hollow-fiber membrane reactors immersed in each solution (4 M and 3 X 10 (-2) M mercury (II) plus 10 (-2) M and detection at 290 nm based on the uv absorbance of the degradation products. |

Pre-column derivatisation using acetic anhydride and 1,2,4-triazole in the presence of mercuric chloride was employed to allow detection in 325 nm. Gradient elution was required to elute amoxicillin, ampicillin, penicillin G, cloxacillin and dicloxacillin derivatives from a C18 reversed phase column using buffer-acetonitrile mobile phase. |

The extract is deproteinized with sulfuric acid and tungstate, filtered, and concentrated on a conditioned C18 solid phase extraction column. Penicillin V and benzyl penicillin are then eluted from the column with 1 mL 60% acetonitrile-35% water-5% 0.2M buffer solution and derivatized with 1 mL 1,2,4-triazole-mercuric chloride solution at 65 degrees C for 30 min. |
