本研究通过响应面法(RSM)优化了Phlomis stewartii植物提取物的机械提取工艺，采用Box-Behnken设计(BBD)对转速(X1)、溶剂体积(X2)和提取时间(X3)进行参数优化，获得最高提取率(18.92%)和生物活性成分含量。通过HPLC和GC-MS鉴定出羟基苯甲酸、p-香豆酸等关键酚类化合物及噻唑 ...

本研究采用色差分析、顶空固相微萃取-气相色谱-质谱联用（HS-SPME/GC-MS）和高效液相色谱-二极管阵列检测（HPLC-DAD）技术 ...

High performance liquid chromatography, (HPLC) and Gas chromatography (GC) work by separating complex mixtures into individual compounds. In each process you need to separate in order to identify, ...

Traditional soda lime silica (SLS) glass bottles have long been the industry standard for the packaging of solvents; however, they may introduce unwanted ions such as Na+, K+, Ca++ and Fe+++ over time ...

For some chromatographers, their first inkling that high-performance liquid chromatography was going to be a big deal came in 1969. That year, they traveled to Las Vegas to attend the fifth in a ...
