High-Purity Salts for Instrumental Inorganic Analysis


Sample preparation in instrumental trace analysis requires extremely pure preparation reagents – because any impurity can compromise measurement accuracy. With Suprapur® high-purity salts from Merck, you can have the fullest confidence in your analytical results

We provide salts with purities from 99.99% up to 99.9999% - so you will definitely find the right product for your application. Suprapur® high-purity salts for sample preparation in instrumental analysis are produced under strict conditions in a clean room area using sophisticated production and crystallization techniques. Our ISO 9001 quality management makes sure that Suprapur® salts show the high batch-to-batch consistency you have come to expect from Merck. A batch-specific Certificate of Analysis (CoA) with extensive impurity profile is available for each product.
