12 Reinventing Gas Chromatography
No relevant progresses in GC autosampler technology have been introduced for many years. HTA reinvents the market by introducing a new GC autosampler lines: HT3000A (autosampler) and HT3100A (autoinjector). Innovative functionalities, easiness of use and extraordinary performance distinguish these new autosamplers and place them at the forefront of the GC autosampler market. HT3000A is the most compact autosampler on the market while offering top-class sample capacity: 121 positions for 2ml vials are available in the standard version.
It is the first autosampler in the world featuring a touch screen display that provides easier system accessibility and usability, simplifying instrument control, also by inexperienced users. HT3100A offers automation for processing up to 15 samples, so it represents the ideal solution for labs that run small sample batches and care about reproducibility and reliability. Quick set of autosampler parameters can be done by the free PC control (HTA Autosampler Manager) provided along with HT3100A, while all the routine operations can be managed by its dedicated keypad. To run the analysis, simply push the START button and all the samples in the rack will be automatically processed, without the need for further assistance by the operator.
HT3000A and HT3100A fit all GC and GC/MS systems available on the market, more or less recent models, regardless of the GC brand. They can be configured serving up to two injectors, with only one tower, in the most of the supported GC. Furthermore, they can be easily moved between GCs, also of different brands, when the workload changes.
Moreover, thanks to their versatility, they can use different kind of syringes with volume from 500 nanoliters to 100 microlitres, to suit all applications. In fact they can handle all the sampling techniques, even the most sophisticated: internal standard technique (also known as sandwich injection), multi-phase, ambient headspace, priority injection, nanoliter injection and much more. They are also provided with an outstanding solvent capacity allowing longer unattended operations and offering double wash step capability for superior analytical performance. Finally HT3000A and HT3100A are the fastest liquid autosamplers available on the market: the injection is performed in less than 100ms.

New Range of Laboratory Gas Generators
F-DGSi offer a complete range of lab gas generators, fulfilling the requirements of all laboratory analysers such as: LCMS, GC, ICP, DEDL, IRTF, TOC, NMR, AA, electronic noise, rheology, particle sizing by laser diffraction, DSC, and sample prep autosamplers.
Whatever customer’s needs, their generators enable users to produce Nitrogen, Hydrogen, Pure Air with purities higher than 99.9999%.
Following extensive market research and technical development, F-DGSi are now introducing to the market the brand new ALLIANCE range of laboratory Gas Generators.
Thermo Fisher Scientific, Inc provides invaluable assistance with the HPLC Method Development Calculator to chromatographers looking to optimise methods with the latest column technologies. This interactive range of online tools is hosted on the Thermo Scientific Chromatography Resource Centre and helps calculate initial conditions for gradient and isocratic methods. In addition, an LC column selection tool is provided to assist in the choice of the appropriate column for any application. With the ability to significantly reduce the time spent in experimentally defining optimal analysis condition, the HPLC Method Development Calculator provides users with quick and easy access to the technical expertise of chromatographers at Thermo Fisher Scientific.

A completely new Hydrogen, Zero Air and Nitrogen product line, the Alliance range of generators incorporates the latest technologies available, in an a sleek and appealing design. The Hydrogen range comes as either a bench top instrument specially conceived for the traditional analytical lab or as a Rack type system, more suitable for customers that require multiple units and have limited space in which they can be placed.
The Nitrogen gas generators are quieter, more efficient and offer the user more functionality in control than anything else on the market. F-DGSi can also offer both PSA and Membrane technology depending on the application and end user preference. To compliment the generators they also provide complete filtration and purification solutions for the feed air supply, together with post-treatment and gas storage systems.
IQ/OQ documentation, full service support from specification to physical installation on site, as well as the on-going preventative maintenance of the entire package, provide complete peace of mind when using an F-DGS product.
Thanks to the gas generators of F-DGSi, all the problems associated with cylinder gases are eliminated. These products are manufactured in Europe, according to the standard ISO 9001.

New Data Demonstrate the Value of Zetasizer µV in Protein SEC
Two new, free to download, technical notes from Malvern Instruments describe the function and benefits of using the Zetasizer µV as a detector for size exclusion chromatography (SEC), focusing on its suitability for protein characterisation. Capable of dynamic (DLS) and static light scattering (SLS) detection, the compact
Zetasizer µV simultaneously measures absolute size and molecular weight, maximising the information produced by each measurement to increase experimental productivity. The OmniFACE connection interface from Malvern Instruments enables the Zetasizer µV light scattering detector to be readily integrated into any third party size exclusion chromatography (SEC) system.

www.malvern.com/TechNote-Zetasizer-connection details how to connect the Zetasizer µV to users existing SEC system to enhance functionality. It explains how to make the necessary fluidic and electrical connections to the chromatograph, OmniFACE and the Zetasizer µV to begin data collection. Examples illustrating connection to the most popular SEC systems are provided.
www.malvern.com/AppNote-Zetasizer-Protein describes the advantages of using the Zetasizer µV for SEC measurements in the characterisation of proteins. These include: automated operation to give both protein size and molecular weight,
complete integration with the SEC software, rapid switching between batch and chromatography modes, and a low volume flow cell to minimise band-broadening.
