More double or triple bonds(unsaturation) give lower Rƒ values. These plates do notcontain fluorescent indicator. Visualization is usually bycharring with acid. The product is light sensitive andshould be stored in the dark. Activate plates for 1 hourat 110°C prior to use for improved separations.5369Modified TLC PlatesReversed-Phase Separation (RPS)• Hydrocarbon impregnated plates provide a lessexpensive alternative to bonded plates for analysis ofpolar samplesModified Silica Gel Plates**• For unique applicationsMODIFIED UNIPLATESDESCRIPTION QTY.
