    Notes: Reprenant l'etude de la constitution de l'acide chondroïtine-sulfurique, nous avons pu établir: 1° Que la liaison chondrosaminique se trouve bien en C1-C4, conformément aux conclusions de Wolfrom.2° Que la liaison glucuronique se trouve en C1-C6 et non pas C1-C3.3° Que le groupe sulfate est situé en C3 ou C4 de la chondrosamine.

    Notes: Nineteen halogenated and/or nitrated diphenyl ethers (currently listed in EPA Method 8111) have been separated on a DB-5/ DB-1701 column pair connected to an inlet splitter and separate electron capture detectors. Retention times are included for 10 additional compounds evaluated for their suitability as internal standards or surrogate compounds for incorporation into Method 8111. Method reproducibility and linearity are discussed, and results are presented for extracts of two real samples spiked with the 19 diphenyl ethers and analyzed using the dual-column dual-detector arrangement.
