General description
25 Glass plates 20 x 20 cm
Aluminiumoxide plates are used to analyze basic and neutral compounds at different pH levels. Depending on the pH range in question, professionals can choose between two kinds of aluminum oxide plates. Under aqueous conditions, basic aluminum oxide plates are best for separating basic compounds, while neutral plates are ideal for separating neutral compounds. Available with or without a fluorescence indicator, our TLC aluminum plates handle a wide variety of applications thanks to neutral and basic aluminum oxides with 60 Å and 150 Å pore sizes.
Application
- Surface-enhanced resonance Raman spectroscopy as an identification tool in column liquid chromatography: This research utilizes TLC plates in conjunction with surface-enhanced resonance Raman spectroscopy to refine the identification processes in liquid chromatography. This method is particularly useful for chemists and material scientists who require precise analytical techniques for complex sample matrices in pharmaceutical and environmental labs, thus meeting the needs of principal investigators and lab technicians in various sectors (Seifar RM et al., 2000).
