selective identification

The fluorescent and colorimetric identification of sensors A-F for the common alkali metals, alkaline earth metals, transition metals and heavy metals were tested, it was found that this type of sensors has a good selective recognition ability for Fe+.

通过探针A-F对常见的碱金属，碱土金属，过渡金属及重金属的荧光和比色识别实验发现，这一类探针对Fe3+具有优异的特定选择性识别能力。

Retention time locking ( RTL) technique was used for quick identification of specific congeners, with selective ion monitoring ( SIM) mode for mass spectrometry ( MS) detection, resulting in higher detection sensitivity.

保留时间锁定（RTL）技术帮助快速定性单个的同分异构体。选择离子监测模式（SIM）保证了很高的测试灵敏度。

Conclusion The methods of identification, check and quantitative determination are simple, accurate, reproducible and highly selective. They can control the quality of amlodipine besylate tablets validly.

结论处方设计合理，测定方法操作方便，结果准确，重现性好，能有效地控制苯磺酸氨氯地平片的质量。

Biolog ( computer aided numeric taxonomy method), gas chromatographic analysis of fatty acid methyl esters ( FAMEs), basic bacteriology, selective media and pathogenicity test were compared for identification of 18 pathogenic bacteria from rice. Biolog and FAMEs were more believable and rapid methods.

对Biolog细菌鉴定法（借助于计算机的数值分类法）、甲基脂肪酸气相色谱分析法（FAMEs）、基础细菌学、选择性培养基及致病性测定等方法鉴定18个水稻标准病原细菌进行了比较。
