Separations is a fundamental scientific discipline focused on the isolation and purification of components from mixtures. Through techniques such as chromatography, distillation, and filtration, separations scientists separate substances based on their physical or chemical properties. This field plays a crucial role in various industries, including pharmaceuticals, food and beverage testing, environmental science, materials research, and more. Explore how separations techniques enable precise analysis, quality control, and the development of innovative products.
Over the years, TLC plates have become scientists’ best friend for quick, simple, versatile and inexpensive analysis for separation & identification of chemicals. Applications range from reaction monitoring to sample preparation, and include compound purity evaluation, optimization of chromatographic conditions, quantitative analysis and much more. Because no plate is universal for all possible applications, SiliCycle has bee…
