Breakthrough Nanoscale Infrared Spectroscopy Technology
Anasys Instruments is pleased to introduce its highly innovative nanoIR™ platform, a powerful new measurement tool that reveals the chemical composition of samples at the nanoscale.
“The goal of nanoIR technology is to overcome major barriers in AFM and conventional IR spectroscopy,” explained Dr Craig Prater, Anasys Instruments’ Chief Technology Officer. “AFM has outstanding resolution, but no ability to perform chemical spectroscopy. IR spectroscopy is a benchmark tool for chemical characterisation, but lacks spatial resolution to address nanoscale problems. Anasys has focused on bridging these gaps.” Anasys Instruments Co-Founder and Vice President of Product Development Kevin Kjoller, added: “In addition to revealing chemical composition, the nanoIR system provides high-resolution characterisation of local topographic, mechanical, and thermal properties.”
The nanoIR system combines the nanoscale spatial resolution capabilities of atomic force microscopy (AFM) with infrared spectroscopy’s ability to characterise and identify chemical species. Users of nanoIR technology can quickly survey regions of a sample via AFM and then rapidly acquire high-resolution chemical spectra at the selected regions. The system can also be programmed to automatically acquire spectra from an array of points across the sample. Mechanical and thermal properties, such as local thermal transitions, may also be mapped with nanoscale resolution. Potential nanoIR application areas include polymer blends, multilayer films and laminates, organic defect analysis, tissue morphology and histology, subcellular spectroscopy, and organic photovoltaics. Polymer spectra acquired with the nanoIR system are rich, interpretable, and have demonstrated good correlation with bulk Fourier transform infrared (FT-IR) spectra. The nanoIR software allows researchers to export nanoscale IR absorption spectra to standard analysis packages. With this interface, nanoIR spectra can be used to rapidly analyse samples and identify specific chemical components.

New Columns Accelerate LC/MS Analysis of Synthetic Oligonucleotides
Phenomenex Inc introduced Clarity® Oligo-MS™ columns for rapid and efficient LC/MS characterisation and quality control of synthetic
RNA and DNA. Based on the company’s core-shell particle technology, the new C18 columns deliver significantly shorter run times than traditional media, along with increased resolution and sensitivity. With the high resolving power of Clarity Oligo-MS, impurities in complex synthetic mixtures can be separated from the peak of interest in less than 10 minutes.
These new Oligo-MS columns, which are part of the Clarity BioSolutions portfolio, are packed with either 2.6µm or 1.7µm particles, enabling high efficiency on any HPLC or UHPLC platform. The Clarity Oligo-MS 2.6µm columns operate at reduced backpressures compared to other oligonucleotide-specific columns, delivering UHPLC performance on any LC instrument, and methods are easily transferable. The Clarity Oligo-MS 1.7µm columns boost the performance of existing sub-2µm methods on high-pressure systems.
With traditional, fully porous particles, efficiency decreases as flow rate increases, resulting in loss of resolution and sensitivity and longer overall analysis time. The Phenomenex core-shell technology enables high resolution and sensitivity over an extended linear velocity without generating excessive backpressure. These columns provide roughly twice the efficiency of fully porous 3-micron columns and three times the efficiency of fully porous 5-micron columns, with significantly lower limits of detection and quantitation.

New Industrial Rotary Evaporator After 10 successful years in the market, Buchi’s 20 litre Rotavapor®
The new Rotavapor®
R-220 is ready for an
upgrade. Buchi has refined its industrial Rotavapor implementing new accessories and technologies with its new Rotavapor R-220 SE (Second Edition).
R-220 SE focuses on safety and ease-of-use. The concept behind all
Buchi equipment stems from the idea that with easy handling, safer operation is achieved. The patented EasyClamp executes fast and safe installations while securing glass joints. The simplistic intuitive design of the control panel provides essential information including bath, vapor and cooling temperatures without complicated menu navigation. Additional safety precautions can be taken by attaching an optional safety enclosure, which does not restrict access to the glassware.
Technological advances come in the form of the new level sensor and USB module. Minimise the time spent supervising the evaporation process by automating the endpoint with the receiving flask level sensor. The USB module is capable of recording data and interfacing with peripheral equipment to provide a state-of-the-art large-scale evaporation solution. Intelligent, easy-to-handle, and above all, safe operation makes the new R-220 SE the right decision for your large-scale evaporation needs.

Automated Nanoparticle Characterisation System in use at the University of Oxford
NanoSight announced the release of the NS500 system. The NS500 incorporates new hardware and software to deliver NanoSight’s growing capability in particle-by- particle characterisation, in an automated package. The first system is in use at the University of Oxford in the Nuffield Department of Obstetrics and Gynaecology of the John Radcliffe Hospital as part of a programme supported by the Wellcome Foundation. NanoSight’s technology, known as Nanoparticle Tracking Analysis (NTA), provides a high-resolution particle size distribution, and not by DLS (dynamic light scattering). NTA detects individual; particles as small as 20nm and, in real time, simultaneously tracks and sizes whole populations. The result is a particle size distribution that provides researchers with the over view of their samples showing everything in the whole range 20 - 1,000nm. NTA also provides count and concentration, together with a unique view that validates these results.
The NS500 adds fluorescence capability, enabling the user to tune into individual particles, with sensitivity to detect individual quantum dots whilst eliminating background interference of other particles and media. Standard beads may be used to bind to single particles for optimum study. The fluid handling capability of NS500 provides the user with auto sample presentation, optimal dilution and in-situ cleaning. It is now a routine process to clean the cell with the ability to purge, flush and load samples through user-customisable software. Dilution may also be controlled in this way. Ease of use is enhanced with an autofocus function for readily homing in on the particles in the laser beam. This is combined with two software-controlled motorised stages to ease use, a direct response to user market research. The temperature control of the cell offers a broader range (15˚C to 55˚C) arriving at the set point rapidly for faster sample measurement and turnaround time.
EXHIBITORS COMMENTS
“A lot of interest and excitement on booth was generated with the launch of PerkinElmer’s new ICP-MS instrument, NexION 300. The booth traffic over the first three days was good, generating a good number of leads, and PerkinElmer were active in both the poster and oral presentations.
Overall, we feel that Pittcon had shrunk again this year, in terms of the number of registrants and size of exhibitor booth space. We support discussions to investigate the opportunity for the show moving to a bi–annual event, alternating with Analytica in Europe. We will assess our level of participation for 2011 based upon the return from this year’s show.”
Nicola Vosloo, European Market Development Leader, PerkinElmer
“Having been an exhibitor at Pittcon since 1984 I can tell you that it has been on the decline for a while now. Many, many years ago it was a huge, exciting event that could only fit into a few trade show venues in the United States. Now, I dare say, it would fit into virtually any medium-sized American convention hall. Why, then, are we still frequenting the likes of Orlando, Atlanta and New Orleans instead of exploring places like San Francisco, Seattle, San Diego, Las Vegas, Salt Lake City, Dallas, even Los Angeles?
Just as important, why is this meeting being held every year? The focus of the show has changed with fewer purchasers attending; in fact it has become more of a business-to-business meeting rather than a show for end-users of our equipment. Having said that, it is still the place to launch instruments – the media presence is second to none. Quality of leads is fair. Booth traffic is fair. Orlando is not the best choice, and Atlanta is even less desirable to us.”
Geof Wyatt, President, Wyatt Technology Circle no. 85
“We will appear at Pittcon to promote our instruments every odd year (2011, 2013). We had a small booth this year, just to be able to promote our Analytical Services. I believe the show went better than expected for what we were promoting this year. We will return to Pittcon in Atlanta in full force, and present our latest products. I personally realised that many other companies scaled down significantly. We’d like to see Pittcon alternate with Analytica in Europe; Pittcon in even years and Analytica in odd years hopefully.
