Custom Premix Selecting "Custom Premix" option means that all of the beads you have chosen will be premixed in manufacturing before the kit is sent to you.
Ion Chromatography (IC) is a form of liquid chromatography exclusively focused on ionic analysis. IC is used in industries as diverse as environmental, power, semiconductor, electronics, and pharmaceuticals. Samples need to be soluble in the solvent and free of particulate impurities prior to IC analysis. It is also important that the sample filtration method does not add inorganic extractables to the sample. Merck offers filtration materials specifically for preparing IC samples, featuring:
Low-binding membrane
Low IC extractables
Materials to clarify both aqueous and mild organic solutions
