In this work, three certified milk powder materials with different PCDD/Fs levels were Soxhlet-extracted and then cleaned up using Power-Prep system automatically. PCDD/Fs and planar PCBs were determined using isotope dilution and high resolution gas chromatography-high resolution mass spectrometry.

In fact, not only was rhythmic complexity of this repertoire largely unmatched for five and a half centuries, with extreme syncopations, mensural trickery, and even examples of augenmusik(such as a chanson by Baude Cordier written out in manuscript in the shape of a heart ), but also its melodic material was quite complex as well, particularly in its interaction with the rhythmic structures.

而事实上，这些作品不仅仅有着大部分在550年内无人能及的节奏复杂程度（极端复杂的切分音和记谱），比如augenmusik（如由Baude Cordier通过非记谱手法自由创作的chanson）；并且他们的旋律素材也相当复杂，尤其是其在节奏组织中的配合尤为复杂。
