[15 Nov 2018 | ]

While talking to customers about their samples, a frequent topic that comes up is whether or not their samples are branched.  Fortunately, I work primarily with Malvern Panalytical’s gel permeation / size exclusion chromatography (GPC/SEC) product range, which in addition to providing molecular weight, intrinsic viscosity (IV), and hydrodynamic radius (Rh) data, offers the ideal technique to observe, and even quantify, the extent of branching within a sample.  In this post, I’m going to describe what it means for a sample to be branched, how branching affects a sample’s molecular …

“It’s impossible to know what happens in the fog of war” said a former US Secretary of State.  But the scientists at Sandia Labs in New Mexico are working to fix that, with the help of a Spraytec laser diffraction system.
The Spraytec is used to measure the droplet size of the airborne droplets, to verify the fog being created is an accurate replica of what is found in nature.  By creating fog droplets with a known droplet size, fog environments are created that accurately replicate those found in specific situations. …

Of all the chemical processes in the fine chemical and pharmaceutical industries, cross-coupling reactions are among the most important.  This often involves platinum group metal (PGM) catalysts, which then must be separated from the product to avoid contamination of the product by these regulated elemental impurities (USP<232>), as well as avoiding that these valuable materials enter the waste stream.
Here is where the process chemists step in to save the day, developing methods to scavenge metal catalyst, tailored for effectiveness with each new compound.  This is an iterative process, and metals …

[9 Oct 2018 | ]

Analyzing glass disks with an X-ray fluorescence (XRF) spectrometer remains the fastest and most convenient method for the chemical analysis of solid samples. However, the investments made in XRF and fusion equipment sometimes not always yield to the expected analytical results and estimated financial pay-offs.
Our experts recently published a white paper that tells you why.
Whether it has to do with inappropriate reference materials, wrong calibration of the XRF, inadequate sample preparation or incompatibility between the fusion instrument and spectrometer, these issues can easily be solved with the help of end-to-end expertise. …

[27 Sep 2018 | ]

Technology developments have fundamentally changed the way elemental analysis can be performed. In the past elemental analysis techniques, like ICP and floor-standing wavelength dispersive X-ray fluorescence (WDXRF), were limited to central laboratories. Over the past two decades, the performance of smaller energy dispersive X-ray fluorescence (EDXRF) analyzers have improved a lot, mainly due to the rapid development in electronics and detector technology. This has enabled benchtop XRF systems, like Malvern Panalytical’s Epsilon range, to perform norm-compliant analysis. It has become possible to bring elemental analysis towards the sample, decreasing feedback …

[5 Sep 2018 | ]

How can we obtain the applied field strength?
When performing electrophoretic light scattering (ELS) measurements, the sample is exposed to an externally applied electric field, and we observe the extra movement that the particles undergo as a result of the applied field with the changes in the phase difference between the un-scattered reference laser beam and the scattering from the particles. The electrophoretic mobility µ is the particle velocity v divided by the electric field strength E, where the field strength is the applied voltage over the distance between the electrodes [typically …

Recently passengers were forced to evacuate a flight at Barcelona airport after a passenger’s mobile phone, connected to an external lithium battery pack, burst into flames.
It is a situation like this that makes us once again realize how very dependent we all are on electricity. Just about everything we use is powered in one way or another. More and more mobile devices are used which get ever more powerful and combine various tasks in one single machine. With this increasing performance and consequently increasing energy consumption of mobile electronics, the requirements …

Get out the bug spray! Mosquito season is upon us in most of the United States…

Near-infrared spectroscopy (NIRS) measures the absorption of light by organic molecules; NIRS is a noninvasive and cost-effective spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from about 700 to 2500 nm).
Malvern Panalytical’s ASD LabSpec NIR analyzer is being used in the fight against Zika and Dengue.

NIRS was first used to simultaneously predict the age and species identity of two morphologically identical malaria vectors1. Malaria, caused by a mosquito-borne blood parasite, is the …

Binding affinity and Kd, Customer experience, Isothermal Titration Calorimetry, MicroCal »

[5 Jul 2018 | ]

Isothermal Titration Calorimetry (ITC) is considered the ‘gold standard’ biophysical assay to determine the binding affinity/dissociation constant for any interaction involving proteins, nucleic acids, or lipids. ITC also determines the binding stoichiometry (related to the number of binding sites), and the binding thermodynamics.
MicroCal LLC, now part of Malvern Panalytical, launched the world’s first commercial ITC instrument, the OMEGA, in 1987 (there are several OMEGA ITCs still in use today!).  MicroCal then followed this success with the MCS ITC in 1992, the VP-ITC in 1998, and the iTC200 in 2007. In …
