J Chromatogr A. 2008 Feb 8;1180(1-2):32-41. Epub 2007 Dec 7. After preconcentration with C18 solid-phase extraction cartridges, both river and sea water samples also showed the signature of the FAE oligomers. The UV-vis response factors of the derivatives of individual FAE oligomers vary little with the number of carbon atoms in the alkyl chain, n, and the number of ethylene oxide units, m. |

J Sep Sci. 2006 May;29(8):1155-65. Chromatographic behavior of synthetic block (co) oligomer samples (EO) n (PO) m (EO) n and (PO) n (EO) m (PO) n with different distribution of propylene oxide (PO) and ethylene oxide (EO) monomer units was investigated on three types of stationary phases on zirconium dioxide support: Zr-PS (polystyrene), Zr-carbon, and Zr-carbon C18. |

Langmuir. 2004 Nov 23;20(24):10648-56. This study investigated the mucoadhesive property of a hydrophobically modified copolymer N-isopropylacryamide and glycidylacrylamide NIPAM-N-Gly-(C18) 2 (NIPAM-Gly). When compared with similar investigations with poly (ethylene oxide), these results provide insights into both the chemical characteristics and the solution conditions that determine the mucoadhesive properties of polymers. |

J Chromatogr A. 2006 Jun 30;1119(1-2):3-10. Epub 2005 Dec 1. The first-dimension RP system employed a 120 min gradient of acetonitrile in water on a C18 microbore column at the flow-rate of 10 microL/min. A comprehensive 2D RP-NP HPLC method was developed for comprehensive 2D separation of ethylene oxide-propylene oxide (EO-PO) (co) oligomers. |

J Chromatogr A. 2008 Aug 29;1203(1):47-53. Epub 2008 Jul 11. After preconcentration with C18 solid-phase extraction cartridges, FAEs were also characterized and quantified in environmental samples (river and sea water). The response factors decreased when the number of ethylene oxide units, m, increased, reaching constant values of ca. 0.40 and 0.65 for the n=8 and 18 series, respectively, when m> or=3. |

Epub 2008 Mar 21. The hydrolysis and condensation of tetramethoxysilane (TMOS) in the presence of poly (ethylene oxide)-block-poly (propylene oxide)-block-poly (ethylene oxide) (P123) and results in monolith with MSU-type mesoporous structure embedded in the skeleton of the interconnected macropore. Moreover, the chromatographic property of C18-grafted monolith is investigated in the separation of aromatic molecules. |

J Chromatogr B Analyt Technol Biomed Life Sci. 2008 Jun 15;869(1-2):138-41. Epub 2008 May 10. Chromatographic separation of ORI and the IS was achieved with a Kromasil C18 5-mum column (250 mm x 4.6 mm) using -water (50:50, v/v) as mobile phase at a flow rate of 1 mL/min. This HPLC method was applied successfully to the pharmacokinetic study of ORI-loaded poly (caprolactone)-poly (ethylene oxide)-poly (caprolactone) copolymer nanoparticles (ORI-PCL-PEO-PCL-NP) in rabbits, given as a single intravenous injection at the dose equivalent to 2mg of ORI/kg, and the pharmacokinetic parameters for ORI were compared with a single intravenous injection of a ORI solution at the same dose. |
