A guide to eliminating problematic polymorphs and fast-tracking stable solid forms with X-ray powder diffraction

Progressing drug development without fully understanding the structure and stability of polymorph variants can quickly lead to potential safety, efficacy or quality issues. Gaps in polymorph profiling can also lead to ambiguity in patent applications, which can have disastrous consequences even years into a drug product’s lifecycle.
A clear understanding of an API and all its forms – through solid form analysis – could improve the chances of regulatory approval, decrease the time required to get a drug product to market, and protect potential revenues.
This guide explores the use of XRPD as a powerful tool to:
· Develop and improve pharmaceutical formulations
· Ensure quality standards are met throughout the drug development workflow

Accurate analysis of precious metals Pt, Rh and Pd and other elements in car catalytic converters

Catalytic converters are designed to remove toxic gases and pollutants from car exhaust gases. Therefore, they contain the precious metals Pt, Pd and Rh. When the car reaches end of life the converter is scrapped. The precious metals are recovered in a recycling chain comprising several different stakeholders, from scrap yards to toll refineries. Due to their high value, accurate analysis and processing of the precious metal content is critical to ensure a maximum return in recycling.
This application note shows a safe, easy and accurate method for providing data giving full insight into the composition of the to-be-processed converter.

Multipurpose Titrator MPT3: pH Titrations Tips and Tricks

The stability of a colloidal sample will vary with pH, and as such, pH titrations are a common experiment to assess these changes and to determine over which pH ranges a sample is stable (or not).
The MPT-3 Multi-purpose Titrator for the new Zetasizer Advance range, allows the user to do this. In addition to traditional size or zeta potential measurements across the pH range of choice, the MPT-3 allows the user to unlock a greater understanding of their samples by setting up pH titrations in different ways.
These are discussed below. :

Flexibility between lab and fab

Compound semiconductor functionality is all about the layer structure. But unlike a cake, it’s rare that you wish to slice up your wafer to see what is going on inside.
Fortunately, though, in this instance you can turn to metrology technologies, such as X-ray diffractometry (XRD), to generate accurate and precise structural metrology in a non-destructive manner. Here, advanced capabilities beyond the rocking curves are becoming ever more important for the production of epitaxial wafers.

Optimizing Metal Powders for Additive manufacturing

In recent years, additive manufacturing (AM) has evolved from a prototyping tool to a still new, but established and economically viable choice for component production. Annual sales of metal AM machines have grown from fewer than 200 in 2012 to almost 2,300 in 2018 as the aerospace, energy, automotive, medical, and tooling industries have embraced the technology.
The use of AM in manufacturing is driving growth in the market segment dedicated to metal materials – which is expected to account for a quarter of the market by 2023.

Nanoparticle number concentration measurements by multi-angle dynamic light scattering

We present the use of Multi-angle Dynamic Light Scattering (MADLS®) for the measurement of nanoparticle concentration. We describe the theory of the method and its application to nanoparticles made of gold, silica and polystyrene, with diameters ranging
from 30 to 400 nm, and demonstrate some of the limitations with particles of sizes 500 nm and above.
We evaluate the method accuracy, linearity and reproducibility, as well as the operational nanoparticle concentration and size range. We show that the concentration working range depends on the material’s optical properties, size and concentration. Here it is shown that the level of accuracy that can be expected for the concentration of particles is typically within 50% of the nominal value across a range of materials and sizes and, for some samples, within 20%.
The repeatability of the measurements, in terms of relative standard deviation, is typically below 30%. A linearity of within 40% across a concentration range of 3·108 to 2·1011 mL−1 for concentration measurements was also demonstrated by using gold nanoparticles and gravimetric dilutions for method validation.
Overall, we show that MADLS® is a rapid and straightforward method for the reproducible measurement of particle concentration, as well as size, requiring minimal sample preparation, without the need to calibrate using a pre-determined concentration series, and applicable to a broad range of materials. These features make it an ideal tool to support both the development and quality control of particle materials for a broad range of applications.

GPC analysis of polysiloxanes

Gel permeation chromatography (GPC) is at the heart of polymer characterization. This characterization technique is implemented throughout the life of the material.This can include after initial polymerization, before and after purification, after post-polymerization modification, in the final formulation, after aging, failure and/or degradation.
The primary focus of analyzing polymers using GPC is to characterize their molecular weights and molar mass distributions. There are many motivations behind determining the molecular weight including predicting how the products' properties will be affected and determining how well a reaction went. In addition to molecular weight, scientists also want to know about changes to the sample’s structure, branching, size, solution viscosity and compositional changes; the OMNISEC multi-detection GPC system provides this information with the highest level of sensitivity.
The OMNISEC uses a combination of refractive index, light scattering, UV/vis spectrometer and viscometer detectors to provide a far more complete characterization than the relative molecular weight results provided by using only RI detection.

Characterization of Microplastics using Morphologically-Directed Raman Spectroscopy

Microplastics, usually defined as pieces of plastic that are less than 5mm in size, are a global environmental and potential health issue. They can be released directly from the production or use of consumer products (primary microplastics), or from the fragmentation of larger plastic objects (secondary microplastics).
Geographically microplastics are present everywhere on Earth and have pervaded our food chains and our drinking water. Though the term “microplastics” was coined in 2004, the increased media coverage of recently published studies meant that 2018-19 was really a wake-up call to the general public about the issues with microplastics. A 2014 study estimated that there was between 15 and 51 trillion microplastic particles floating in the world’s oceans, weighing between 93 and 236 thousand metric tons.

Free 1 year access to latest XRD software & knowledge resources

---for continued research even during the Covid-19 pandemic
X-ray diffraction (XRD) is the only laboratory technique that reveals structural information, such as chemical composition, crystal structure, crystallite size, strain, preferred orientation and layer thickness. Materials researchers, therefore, use XRD to analyze a wide range of materials, from powders to solids, thin films and nanomaterials.
Ultimately, the goal is to obtain a good XRD pattern result with clear, sharp peaks with low background noise. Good data collection is critical towards the next phase, which is data analysis and interpretation. These impact how you draw implications and determine your next steps of your materials research.
During this year, Malvern Panalytical is keen to help you to achieve business continuity in your XRD research. And that’s why we’re happy to share 2 great offers with you!
Free 1 year software for Powder XRD & thin film stress/reflectivity

The OMNISEC Column Calibration Methods: Conventional and Universal Calibration for Sample Analysis

The molecular characteristics of a macromolecule are important parameters to be determined as they all can affect the material’s physical properties and behavior in a final product as well as during processing.
In order to measure and evaluate these parameters (molecular weight and molecular weight distribution, molecular size and structure) size exclusion chromatography (SEC), or gel permeation chromatography (GPC) as it is also known, is one of the most useful tools that can be used.
