Question

英语翻译
Heavy species (Fig.3) are accumulated in a glass trap
quenched in liquid nitrogen (about 77 K) during time typically
between 5 and 15 min according to reactant feed.Then the glass
trap is disconnected from the reactor and products are dissolved
in a solvent (acetone).A known amount of internal standard (noctane)
is added to the mixture which is injected by an autosampler
in an ‘‘Agilent 6850’’ gas chromatograph equipped with
a FID and a HP-1 capillary column with helium as carrier gas.
Oven temperature is:313 K held 30 min,rate 5 K min\21,453 K
held 62 min.Heavy species were identified by a gas
chromatograph–mass spectroscopy (GC–MS) system working
in the sameconditions as the ‘‘Agilent 6850’’ gas chromatograph.

Answer 1

沉重的物种（图3）是在一个玻璃陷阱积累
在液氮中骤冷（约77 K）的时间通常在
然后玻璃
陷阱是从反应器和产品断开的溶解
在溶剂（丙酮）.一个已知量的内部标准（正辛烷）
被加入到混合物中,由自动进样器注入
在“6850”'agilent气相色谱仪配备
FID和氦气作为载气的HP-1毛细管柱.
烤箱温度：313 K保持30分钟,1分钟\2率5 K,453 K
由气体确定举行了62分钟.沉重的物种
色谱–质谱（GC–MS）系统的工作
在相同条件下,作为“6850”'agilent气相色谱仪.
