Spectroscopy

High Quality, Complete Reliability

---

MilliporeSigma offers a wide range of high-quality products for a variety of spectroscopic applications. Our comprehensive portfolio includes high-purity Suprapur® and Ultrapur® acids, auxiliaries (modifiers, Suprapur salts, hydrides) for AAS and ICP sample preparation, as well as Certipur® ICP standards for calibration in atomic spectroscopy, which conform to ISO Guide 34 and are directly traceable to international NIST standards.

Spectrophotometric analysis generally requires the use of highly purified solvents and reference materials for instrument qualification. To support such applications, we offer Uvasol® solvents and Certipur® UV/VIS standards that are thoroughly and stringently tested. For sample preparation in XRF (X-ray fluorescence) spectroscopy, our Spectromelt® digestion fluxes and pressing powder tablets provide you with high purity and excellent batch consistency. We also supply a broad selection of Magnisolv™ deuterated solvents to satisfy the most demanding requirements in NMR (nuclear magnetic resonance) spectroscopy.
