Automated sample preparation methods for content uniformity and assay of rosuvastitin tablets
In this application the accroma system proves to be suitable for the automated sample preparation of rosuvastatin calcium tablets (10 mg) for content uniformity and assay.

Use of acoustic methods and current flow measurement in battery research
In this article, the possible uses of the three methods “acoustic attenuation spectroscopy for particle size”, “electroacoustic for zeta potential” and “electric current measurement for electric conductivity in organic solvents” for NMR battery production process were investigated.

Plasmion SICRIT applications overview
This booklet goes through chromatography coupling, online detection, MS Imaging and special applications.

Magnetically driven agitation decoupling events in benchtop microbial STR systems
In this work, Distek characterized decoupling agitation speed thresholds for a 5-L benchtop fermentation system which was operated under a variety of different media viscosity and bottom air sparge rate process conditions.

Sentron ISFET pH probes
Sentron has developed a comprehensive line of wireless high-quality probes for glass-free pH measurements. Sentron’s ISFET pH sensor technology offers accurate and reliable pH measurements for various applications.

Purification of [6]-gingerol using Gilson SCPC‐250 CPC system
This note highlights the ability of a centrifugal partition chromatography (CPC) system (Gilson SCPC‐250) to obtain high purity fractions of an active compound from a small amount of crude extract using five times less solvent consumption than flash chromatography and prep HPLC.

NMR relaxation measurements: their relevance to the physical characterization of particulate suspensions and slurries
This technical note discusses a powerful non-invasive technology for characterizing any solid-liquid or liquid-liquid formulation (i.e., suspensions and emulsions), and introduces the Mageleka MagnoMeter XRS as a simple and affordable instrument for achieving this.

Using NMR relaxation as an aid in understanding formulation of pigment dispersions by Mageleka
In this application note Mageleka demonstrates the importance of understanding all components of a pigment formulation, and introduces the compact next-generation NMR relaxometer, the MagnoMeter, that provides fast, easy, and reliable measurements of dispersion characteristics.

Active pharmaceutical ingredients in AIDS drugs: using NMR relaxation to determine the wetted surface area of suspensions
This application note by Mageleka presents two case studies, where they examine two different API drug materials and show how NMR relaxation measurements from the MagnoMeter can be used to achieve optimal bioavailability.

Dispersions of ink-jet pigments: using NMR relaxation measurements as a quality control tool
The speed and simplicity of NMR-based measurements with the MagnoMeter make it an ideal tool for routine quality control purposes. The advantage of such measurements is that important characteristics of products, from fundamentals to end-use performance, can be monitored quickly and easily and at virtually any industrially relevant solids concentration.
