TLC Plate Selection Guide
Thin layer chromatography (TLC), an analytical technique often used to separate and identify compounds present in a given mixture, can also be used to determine the purity of a particular substance within that mixture
PLC Plates for Separations from Milligrams to Grams
Our Preparative layer (PLC) plates allow separation and purification of samples varying in quantity – from milligrams to grams.
Thin-Layer Chromatography Process
What causes a dissolved mixture to separate when applied to a TLC plate? The thin-layer chromatography process relies on capillary forces. During development of the chromatogram, the mixture of substances is first transported by the mobile phase, then resides on

In this article we present several HPTLC applications and analytical standards for ginsenosides.
Mass Spectrometry
Mass spectrometry (MS) is an analytical tool used to identify compounds, determine chemical structure, and assess isotopic abundance. In MS, samples are ionized, and the resulting ions are identified based on their mass-to-charge (m/z) ratios.
