Product news

In sophisticated analyses, such as of ores, even 1.0 ppb of impurities can have an enormous effect. Among other products, Merck Millipore offers a wide range of high-quality analytical reagents for analyses at these low concentrations. They cover all requirements for every process step in mining.

Advantages at a glance:
• Wide range of reagents and products for the mining industry
• Highly accurate measurements
• Precise results reduce both costs and the use of resources
• Batch consistency and comparable results

Suprapur©, Certipur©, Spectromelt©: Reliable products – consistent high quality

Suprapur© acids and salts for instrumental trace analysis are one example of Merck Millipore's extensive product range for mining. Suprapur© acids meet the highest purity standards and are specified for the ppb range.

As extraordinarily high-quality products for fluxing digestion and sample preparation, Spectromelt© fluxes are suitable for X-ray fluorescence analysis (XRF).

In addition, under the Certipur© brand, Merck Millipore offers a large choice of premium reference materials, including for ICP spectroscopy or atomic absorption spectroscopy (AAS).

Merck Millipore also provides reagents for the determination of mercury as well as metals, metal salts and precious metals.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.

Spectrofluorometers utilize monochromators to select the desired wavelengths, whereas filter fluorometers employ a set of filters. Spectrofluorometers for measuring steady-state fluorescence and lifetime fluorescence (or time-resolved fluorescence) are available, as well as fluorescence microscopes and microplate readers.

It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

X-Ray Diffraction and SpectroscopyX-Ray diffraction & spectroscopy are used in material characterization to discern the structure and elemental composition of a sample. X-Ray diffractometers (XRD) are superior instruments in elucidating the dimensional atomic structure of crystalline materials, including powders, thin films and single crystals. For large unit cells or ordered macromolecules, consider small-angle X-ray scattering (SAXS). X-ray spectroscopic techniques include X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS), both providing simple and accurate methods for determining the elemental composition of a material. Energy dispersive (EDXRF) and wavelength dispersive (WDXRF) XRF spectrometers are available, as well as handheld/portable devices. High-resolution, 3D microstructure characterization of materials can be achieved with X-ray microscopes combining sub-micron resolution imaging with 3D computed tomography.
