mass spectrometry should be used in conjunction with the proposed gas chromatography work to obtain more accurate hydrocarbon characterization and to help identify the source of any petroleum hydrocarbons found in the sediment cores.
1. 质谱法应结合拟议的气相色谱法使用,以便更准确地阐明所含碳氢化合物特点和帮助查明沉淀物样芯中发现的任何石油碳氢化合物的来源。
the amount of work for sediment analyses should be increased to allow for gas chromatography/mass spectrometry analyses in addition to the proposed nickel and vanadium analyses for each of the sediment subsamples.
6. 分析沉积物的工作量应予以增加,以便除了拟议的对每个沉积物子标本进行镍钒法分析外进行气相色谱/质谱法分析。
