1)  spectrum level
谱级
2)  MSn
多级质谱
1.

采用电喷雾多级质谱方法,研究了三个从地衣中提取到的缩酚酸醚类化合物在电喷雾电离质谱中的裂解行为,结果表明它们在电喷雾多级质谱中能得到较多碎片离子,其裂解途径能体现它们的基本结构特征。
3)  GC/MS/MS
二级质谱
1.
According to US EPA method, A GC/MS/MS method was exploited to detect 7 kinds of polychlorinated biphenyls (PCBs) and 13 kinds of organochlorinated pesticides (OCPs).
以美国国家环保局(EPA)方法为基础,开发了7个多氯联苯(PCBs)和13个有机氯农药(OCPs)的二级质谱分析方法,对土壤进行目标物添加实验,回收率在64。
4)  tandem mass spectrometry
二级质谱
1.
The glucosinolates extract were purified with the column filled with DEAE sephadex A-25 and the molecular structures of its major glucosinolates were determined and identified by HPLC-ESI/MS in combination with tandem mass spectrometry.
利用高效液相色谱-电喷雾电离质谱(HPLC-ESI/MS)技术,并结合二级质谱分析,鉴定播娘蒿种子中主要硫苷的分子结构。
5)  secondary spectrum
二级光谱
1.
Use of diffractive-refractive optical system for correction of secondary spectrum;
衍/折射光学系统校正二级光谱的研究(英文)
2.
Design of correction of secondary spectrum for High Spectrum Imaging Instrument(HSII);
高光谱成像仪衍/折射光学系统消二级光谱的设计
3.
Design of correction of secondary spectrum by binary optical element;
利用二元光学器件消二级光谱设计
6)  Energy spectrum level
能谱级
补充资料:谱级分离
分子式:
CAS号:

性质:光栅产生的衍射光谱为多级重叠,通常用滤光片消除光谱级间的重叠现象。如一级光谱800nm与二级光谱400nm和四级光谱200nm的谱线,均出现在焦面同一位置。为消除对一级800nm谱级的干扰,需选用适当的滤光片,滤掉400nm以下的谱线。
