Analysis of Hydrophobic and Hydrophilic Silica TLC Plates
9 Jul 2012In this report, LAESI-MS is used to image molecules separated on a bare silica Thin Layer Chromatography (TLC) plate using the Protea LAESI® DP-1000 system and its proprietary ProteaPlot™ imaging software. This system can be used to analyze compounds separated on both hydrophilic and hydrophobic TLC silica plates, by simply wetting the TLC plates with water. This analytical method can be used to determine both the location and confirm the identity of analytes separated on TLC plates.

Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses.

It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

Thin Layer ChromatographyThin-layer chromatography (TLC), also called planar chromatography, is an inexpensive and simple liquid chromatographic technique used to separate and identify small amounts of compound in a mixture, monitor progress of a reaction or determine purity of substance. TLC plates come in multiple sizes with common adsorbent layers being silica, aluminum oxide or cellulose and high-performance (HP-TLC) plates are also available for increased sensitivity. Other equipment needed includes TLC developing chambers, applicators, TLC sprayers and visualizing devices, such as a viewing cabinet and UV lamp.
