Early Modern Literature in HistoryIn this paper the importance of capillary GC for environmental analyses is emphasized. A number of properties of GC columns affecting the general applicability is discussed. A survey is given of the progress made during the past few years with respect to each of these properties.作者: handle 時(shí)間: 2025-3-22 16:47 作者: Anhydrous 時(shí)間: 2025-3-22 19:53
