Maximize your data
Multi-detection can provide enormous benefits for size-exclusion chromatography. Adoption of a multi-modal detection strategy provides a lot more data about the macromolecules being analysed providing different perspectives of molecular weight distribution and even structural information. The expanded view offered by multi-detection can save …
Held in Cleveland, Ohio, on October 9 – 13, 2011, this year’s Society of Rheology Conference was another great success thanks to the organization of Jonathan Rothstein, Victor Breedveld, Patrick Mather and Andy Kraynik, with a crowd drawn from all over the world.
Plenary speakers included Eric Shaqfeh (also Bingham award winner this year) who spoke on the rheology of vesicle and capsule suspensions. Other plenary lectures were from Juan J. de Pablo who educated us on directed assembly of complex fluids and its application to nanoscale fabrication, David Pine mused …
There are lots of different ways of implementing any type of project – from signing up for a turn-key solution, or at the extreme, buying just the equipment you can’t fabricate in-house and doing every thing else yourself.
Implementing automated process analysis
Implementing automated process analysis is an increasingly popular option and its becoming easier. However, for such a project to be successful, it’s important to engineer a robust process interface and properly integrate the analyzer within any existing control platform. Those who really want to capitalize on their investment also need …
Thanksgiving Day in the U.S. is a great holiday – though it means different things to different people. To some, it means a short work week with the official holiday on the 3rd Thursday of the 3rd full week every November, usually accompanied by the following Friday as a day off as well. To others, it is the unofficial start of the holiday season and “shop to you drop” time of year.
To still others, it means a chance to eat unhealthy quantities of turkey with gravy, stuffing, cranberry sauce, potatoes, …

Take part in a SiC Round Robin
To enable analysts to have confidence that their analytical equipment is working to specification, there is a need to set standards for known grades of Silicon Carbide (SiC) abrasives used by the wire saws when cutting out silicon wafers for use in the manufacture of photovoltaic cells.
Malvern Instruments would like to invite you to take part in a Round Robin study to set an FPIA-3000 circularity specification on a known grade of SiC. Please contact me before 30th November 2011 for more details.

Looking out of the window, you could be forgiven for thinking I’m talking about the changeable autumn weather we’re experiencing at the moment. In fact, as you can see from the video below, changing the measurement cell to allow you to swap from measuring samples dry with the Aero to wet with the Hydro dispersion units is extremely straightforward. The Auto locking cell ensures that robust results can be acheived with the minimum of fuss, whatever the weather is doing outside……….

The imminent arrival of DDL (Drug Delivery to the Lungs) 22 which will take place in Edinburgh, 7-9 December, brings back mixed memories from last year.
The poster judging panel describing the technology of the Morphologi G3-ID system as ‘revolutionary’ and awarding us the Industry poster award was a real high point, but the journey up to Scotland was pretty torturous. There is no doubting Edinburgh’s beauty, but extraordinary snow falls last year made reaching it a major challenge, that had our sat. nav. working overtime.
This year I’m hoping the three days …

The Benefits of Moving from Single to Multi-detector Size-exclusion Chromatography
Multi-detector Size-exclusion Chromatography
Size-exclusion chromatography (SEC) is a useful and uncomplicated technique for analyzing complex macromolecules such as synthetic polymers, polysaccharides and proteins that it hardly needs much introduction. However, its utility can be markedly improved by the use of multiple detectors.
Molecular weight is calculated in different ways by light scattering, refractive index …
Last year we were all still talking about the environment. Now, although the environment remains dominant, the new word on the block seems to be ‘ecology’!
For example, my attention was recently drawn to the term ‘ecotoxicology’ when a Malvern customer reported a successful study; ‘Zetasizer Nano used to accurately characterize nanoparticles in ecotoxicology study’.
This work encouraged me to consider the distinctions between environment and ecology. I had to ask myself, how are environmental toxicology and ecotoxicology different?
A wider ecological perspective
According to Wikipedia, Environmental toxicology examines the harmful effects of chemical, …
With the flu season well underway, many of us will be contemplating a trip to the doctor’s surgery for our annual flu shot. However, recent research suggests that by targeting a preserved region of a protein found in many influenza strains, it might be possible to create a broader flu vaccine that would effectively end the need for these yearly vaccinations.
Ironically, patients who survived infection with the 2009 H1N1 pandemic flu strain developed antibodies capable of protecting the host from a variety of flu strains, which scientists suggest might aid …
