Lab 2: High Performance Liquid Chromatography - Chemistry

High-performance liquid chromatography (HPLC) offers the ability to do just that. HPLC data can be used to complement gas chromatography (GC) or be an excellent alternative to GC when the components are nonvolatile or would thermodynamically decompose under high temperatures. In order to separate mixture components, HPLC takes advantages of

Analytical Vials - MilliporeSigma

Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including
