NEW PRODUCTS ON SHOW AT PITTCON 2013
Ambient Ionisation System Extended to GC/MS IonSense Inc introduced the DART®
GSX™ System for the Agilent®
SHOW REVIEW GC/MSD, for the first time enabling ambient ionisation on a
GC/MS instrument. With this combination, customers can effectively add the benefits of Direct Analysis in Real Time (DART)-rapid analysis with little or no sample preparation and simplified spectral analysis- freeing chemists and analysts to focus their attention on other tasks.
The system includes a DART G12 source and the GSX™ Interface coupled to the Agilent GC/MSD. Routine analyses are facilitated by the QuickStrip™ Sample Cards on the linear rail scanner unit for analysis of up to 12 samples in a single unattended experiment.
"We are excited to be able to extend the benefits of DART to labs that utilise GC/MS instruments," said Brian Musselmen, IonSense President and CEO. "Until now we have only been able to supply DART to customers that have an LC/MS instrument in their labs. Though there are now several hundred DART units in the field, we are looking forward to working with the thousands of labs where GC/MS is the mainstay of their efforts."
Alongside the DART GSX System and its line of ambient ionisation sources, the Company also displayed the ID-CUBE® with its
OpenSpot™ Sample Cards for easy sampling and near-instantaneous results, the DART OS for using OpenSpot Sample Cards as well as other sample form factors, and the DART SVP for complete flexibility and automation of analysis.

In-Show - Online Flow Meter Solutions to Hand
Sierra Instruments, a global leading manufacturer of mass flow meters and controllers demonstrated its online store which offers researchers and scientists customised and calibrated gas flow measurement and control solutions for any application or budgetary requirement.
With a large, factory-direct stock of scientific mass flow meters and controllers available, on-line orders are quickly dispatched for next day shipping with no expedite fees. Sierra’s proprietary selection tool allows customers to easily configure and purchase their instrument of choice without loss of delivery time.
Fun-Display Cloaks Serious Science
Ocean Optics revealed a novel trade show display – a fully functional, in-line gumball sorting machine, which while fun to watch concealed an optical system comprising nearly a dozen spectroscopy measurement stations positioned throughout an 8-foot-tall, 6-sided structure. Stainless steel rails delivered the gumball samples to each station, where spectrometer setups measured chemical composition, colour and reflectivity. The different stations determined characteristics such as absorbance and fluorescence of food colouring and flavours, transmission characteristics of plastic containers and oxygen content in packaging. Techniques as varied as Raman analysis, fluorescence, UV-Vis absorption and NIR spectroscopy were represented.
Each station in the gumball sorter acted as an independent analyser: after measurements were made and recorded, a software response triggered a second device -a motorised gate – to direct the sample to the next measurement or a sorting bin. While a gumball sorter could have been considered whimsical, it enabled the company to successfully demonstrate that the instruments and technique s used could be implemented into a process stream, used in a lab or field setting or incorporated into another sensing device, the Company pointed out.

Column Combination for Lab-Scale Purification Phenomenex Inc announced Kinetex®
Core-Shell media packed in Axia hardware for preparative HPLC and SFC in lab-scale purification. Kinetex 5-micron particles in four phases ¬– C18, XB-C18, Phenyl-
Hexyl and PFP – are now offered in 21.2mm ID Axia packing. This marks the first time that core-shell media has been offered in the Phenomenex Axia preparative format, which can deliver longer column lifetime, and higher efficiencies. Kinetex 5-micron core-shell media is the largest particle in the family and delivers better performance than 5-micron fully porous offerings, with no increase in backpressure. In fact, the new 5-micron media provides 60 to 90% higher average efficiencies compared to the same size fully porous columns with little to no method development, the Company said.
The Phenomenex patented Axia packing and hardware technology, introduced in 2005, eliminates the drawbacks of traditional slurry packing, delivering uniform bed density and dramatic performance advances. “This announcement brings together two award-winning technologies from Phenomenex,” explained J.T. Presley, Brand Manager for Phenomenex. “Every Axia preparative column has been optimised for each packing media to improve column-to-column reproducibility and increase packing densities, resulting in higher efficiencies and prolonged column lifetime.”

Chip-Based MS Broadens Possibilities
Microsaic Systems plc, a producer of MS instrumentation using Micro-Electrical-Mechanical Systems (MEMS) technology, showcased the Microsaic 4000 MiD.
The company is the first to have commercialised mass spectrometry (MS) technology on a chip based on MEMS technology originating from the Optical and Semiconductor Devices Group at Imperial College London. The company’s breakthrough product, the 3500 MiD launched in January 2011, was a step change in ease of use and for its small MS footprint and won an R&D 100 Award.
Bringing together chemical analysis and silicon micro-engineering – the 4000MiD provides detection in an even smaller instrument. Fitting comfortably into a standard lab fume hood, it offers potential for reaction monitoring.
Colin Jump, CEO, Microsaic Systems said: “Offering the smallest footprint in the market, the Microsaic 4000 MiD is a fully integrated, versatile, portable MS system designed for bench chemists. The core technologies are chip-scale versions of traditional mass spec components which can be interchanged rapidly by the user. This modular approach allows users to maintain the system without the need for expensive service contracts and time-consuming call-outs.”

NanoSight introduced the NS300 particle characterisation system for visualising and measuring particles in suspension in the size range of 10-1000nm (material dependent), addressing a wide variety of applications including protein aggregation, exosome and microvesicle research, and drug delivery systems. Built on the company’s signature Nanoparticle Tracking Analysis (NTA) technology this new instrument provides characterisation under the new EU Definition of Nanomaterials, and is particularly suited to the analysis of particles labelled with fluorescent quantum dots.
Dr Patrick Hole, NanoSight’s Head of Product Development, said: “The NS300 is the natural progression from the NS500 and LM10. It takes the most popular features of these instruments and combines them into an easy to use, compact format. We then added in the high capacity motorised fluorescence disc. This disc, capable of being programmed from within the software to present up to six different fluorescent filters, will facilitate a more detailed assessment of fluorophores. It will give users the possibility to analyse each fluorescence population in terms of size and concentration; this ability to identify co-localised fluorophores will greatly enhance specificity and the ability to Phenotype”.
Additionally, the software’s new rheology feature can measure viscosity in the range 0-5 centipoise, using probe particles to inform on non-Newtonian liquids in a shear-free manner, so being specifically applicable to the formation processes of hydrogels.
