Nanoparticle Tracking Analysis, Nanosight, Particle concentration, Tech Talk »

[23 Nov 2017 | ]

Results of a multi-round interlaboratory comparison (ILC) of NanoSight instruments were recently published1, setting a benchmark for repeatability and reproducibility for the Nanoparticle Tracking Analysis (NTA) technique. The limits of measurement were shown to extend beyond the 30 nm –600 nm range (with all NanoSight models), with percentage coefficients of variation (% CV), calculated as sub 5% for monodisperse samples. The process further highlighted how much variability or error might be introduced if inappropriate instrument settings or analytical procedures are used.
As a relatively new technique, there remained questions about the …

Measuring aggregation temperature using the Zetasizer

In dynamic light scattering (DLS), the hydrodynamic size and size distribution of particles in solution can be obtained.  It may be of interest to examine this measurement as a function of time and temperature, or as a ‘trend’, as it is called in the Malvern Zetasizer software.  For biological protein samples, this temperature trend is particularly interesting: although at low temperatures a protein may be stable and show repeatable size (and scattering intensity) measurements, typically at some elevated temperature (Tagg), protein molecules will show a tendency …

Aeris, Customer experience, X-Ray Diffraction (XRD) »

[9 Nov 2017 | ]

I recently had the pleasure to visit a new Aeris customer in Orlando, FL – Louis C. Herring Laboratory. This service lab has been in business for over 60 years, specializing in the analysis of kidney stones, also known as urinary calculi. What I found amazing about this site is that their Aeris actually replaced a Philips Analytical PW1840 system, our first generation benchtop XRD produced in the early 1980s. Their PW1840 ran for three decades, amassing over 41,000 hours of operating time and requiring little to no service through …

Complete phase composition and simultaneous determination of bath parameters with a sample throughput time of less than a minute on a benchtop diffractometer!
The production of aluminium from purified alumina by electrolysis (Hall-Héroult process) is a very energy-consuming process. Frequent monitoring of the electrolytic bath parameters combined with short measurement times and high sample throughput is important to ensure minimum costs for smelter operations. Over the years a number of analytical techniques, including wet chemistry, X-ray diffraction (XRD) and X-ray fluorescence (XRF) have been used to monitor electrolytical bath conditions.

[2 Nov 2017 | ]

Molecular weight measurements with the Zetasizer software?
First a few words of caution: molecular weight or Mw measurements in general are not easy, require time, good sample preparation skills as well as patience. If you are new to the Malvern Zetasizer it might be best to familiarize yourself first with the rapid, user-friendly, and quite forgiving technique of dynamic light scattering (DLS).
OK, with that out of the way, the software can handle static light scattering with the relatively simple concentration series method. All that’s required is

a scattering standard (which is usually …

Downstream in-line monitoring for better processes and products
Every second is critical towards rectifying a plant upset or ensuring efficient plant management. What if you could incorporate in-line analysis for your dry and liquid products?
Companies that introduced in-line particle size analysis at the milling stage noticed significantly less over-milling. Hence seeing as much as a 2% increase in plant throughput. In-line elemental analysis allows petrochemical companies to closely monitor Fe, Ni, V which destroy expensive catalysts.

Binding affinity and Kd, Isothermal Titration Calorimetry, Meet the Experts, MicroCal, Microcalorimetry »

[12 Oct 2017 | ]

Isothermal Titration Calorimetry
Molecular recognition is key in all biological processes and cellular responses. It is critical to characterize the structural and thermodynamic forces behind the recognition and specificity of macromolecular interactions in order to understand the molecular events in a cell. Several biophysical techniques (including fluorescence, circular dichroism, Fourier transform infrared spectroscopy, mass spectroscopy, surface plasmon resonance, and microscale thermophoresis) are used to characterize non-covalent molecular interactions.
Isothermal titration calorimetry (ITC) has become a popular and versatile bioanalytical method for the direct measurement of binding affinity between interacting molecules.  ITC instruments were …

The heavy cost of mining and minerals manufacturing
The importance of minerals as a production resource applies to many facets of our daily lives. For instance, the quality of concrete determines the smoothness of a road surface and the sturdiness of a building. However, with the ever-growing demands for quality cement, many have spurred manufacturing processes leading to hefty costs. Such costs incurred comes from wastage when having to reproduce cement because it does not meet the quality standard.
Based on a mechanical and civil engineering study, 6-15% of construction costs …

I have just come back from presenting my talk ‘Application of Morphologically-Directed Raman Spectroscopy in deformulation and in vitro bioequivalence studies’ at the pharma focus session of Powtech 2017.
The talk indicated how there are still many drug products that have come of patent but do not yet have generic equivalents available and how there is a drive from the regulatory bodies to make health care more accessible and so they are producing many guidance documents to help address this.
I gave an overview of a proposed workflow for developing generic drug …

Is there a maximum viscosity for DLS measurements?
 
The Malvern Zetasizer can determine particle size by dynamic light scattering (DLS). In this technique, the intensity fluctuations are analyzed to find the corresponding diffusion coefficient that led to the fluctuations. The translational diffusion coefficient Dt of a particle is inversely related to its size and the viscosity of the dispersant (or more accurately the hydrodynamic radius rH and viscosity η).

This relationship can be used to predict detectability limits of the technique in general, and this is how we explore the idea of …

Binding Affinity
 
Understanding binding affinity is key to appreciation of the intermolecular interactions driving biological processes, structural biology, and structure-function relationships. It is also measured as part of the drug discovery process to help design drugs that bind their targets selectively and specifically.
We recently launched a new short video showcasing the MicroCal PEAQ-ITC and how it is an essential piece to any biological interaction analysis toolkit for measuring Binding affinity and stoichiometry.

The MicroCal PEAQ-ITC offers key benefits over other ITC systems including:
