The Perfect Start for Accurate Measurements

Analytical Sample PrepRoutine laboratory work involves purifying, enriching or separating for subsequent analysis. Solid, liquid and gaseous substances also have to be purified for production-scale processes. Various chemical and physical methods can be used for this purpose, among these are absorption, adsorption, chromatography, distillation, extraction, ion exchange, filtration, complex formation, crystallization, drying and many more.

Merck offers an extensive range of products for sample preparation with excellent absorptive, adsorptive, filtration and clarification properties. These products can be used for purification but also as reaction and filtration aids, as fillers, additives, or as carriers of active ingredients. In addition, we offer reagents for the preparation of gases, cooling mixtures and for adjusting relative humidity as well as classical laboratory auxiliaries.
