multivariate data analysisThe volatile constituents of the leaves and flowers of Brachychiton rupestris and Brachychiton discolor (Malvaceae) were characterized by GC-FID and GC-MS. A total of 92 compounds were identified. The major component of B. rupestris leaves was 伪 -farnesene (34.57%) while...
The accuracy and reliability of the results of the GC—FID analysis can be assured only if a standard curve is established that is accurate and reliable。 建立HS-GC-FID标准曲线的目的在于通过测定目标化合物的峰面积与浓度的关系,从而对待测样品中的目标化合物进行定量分析。标准曲线的建立是GC-FID分析...
