Microscale HPLC System Combines UHPLC Performance with MicroLC
HPLC Simplicity with UPLC Performance Waters Corporation introduced the new Waters®
ACQUITY UPLC® performance of ACQUITY UltraPerformance LC® H-Class System incorporating the proven, robust and reliable (UPLC) with the operational familiarity of traditional high performance liquid
chromatography. This combination of performance, simplicity and flexibility is designed to help more laboratories realise the scientific and business benefits of sub-2-µm (micron) particle column technology by making it more accessible to a broader range of industries, applications and operators.
With systems currently installed in Waters’ demonstration laboratories worldwide, the ACQUITY UPLC H- Class is ready for customer shipping today.
Beyond improving chromatographic performance when running UPLC columns as well as fully supporting HPLC columns, the ACQUITY UPLC H-Class system closely emulates HPLC workflows, making method transfer from HPLC to UPLC easier and more seamless. Furthermore, the introduction of the ACQUITY UPLC H-Class allows organisations to standardise their approach to LC with a common technology platform that makes the future transition from HPLC- to UPLC-based methods straightforward and practical - from product discovery to product release testing.
The answer to achieving UPLC performance and benefits without fundamentally modifying HPLC workflows came in the form of the ACQUITY UPLC H-Class’ new quaternary solvent manager (QSM) and sample manager (SM-FTN), with flow-through needle design, thereby mimicking traditional HPLC system workflow. The featured QSM and SM-FTN on the ACQUITY UPLC H-Class combine to enable the chromatographer to achieve high separation efficiency using sub-2-µm (micron) particle separations at high pressures. The result is seamless upgrade of chromatographic capabilities.

Eksigent introduced the ExpressLC-Ultra. This new microscale HPLC system runs at column pressures up to 10,000 psi, allowing the use of sub-2 micron particle columns. Along with a new UV detection system, the system delivers all the advantages of microscale LC including solvent savings, reduced sample requirements, and reduced frictional heating.
The new system’s CCD-based UV detector works with microfabricated flow cells to ensure ultra-high sensitivity with no band broadening. The ExpressLC-Ultra’s high UV sensitivity allows detection of impurities at levels as low as 0.05 percent, meeting the needs of researchers in drug discovery and many other applications. The system incorporates Eksigent’s proprietary Microfluidic Flow Control (MFC) technology to generate accurate and reproducible flow rates, from 1 to 50 microliters per minute.
New features make the ExpressLC-Ultra as easy to use as any conventional HPLC instrument. Solvent changes are automated, and tubing and fingertight fittings ensure simple connections. The fiber-optic flow cell is easily connected and exchanged without alignment, and all user-configurable components and plumbing are accessible on the front of the instrument. The ExpressLC-Ultra includes Eksigent’s control software with specialised diagnostic tools. The software provides tools for 21 CFR Part 11 compliance plus flexible data analysis and reporting capabilities. The Eksigent control software also includes integrated drivers for the most widely used mass spectrometry programmes including AB SCIEX Analyst, Thermo Scientific Xcalibur and Bruker Daltonics HyStar.

High Pressure Chemical Reactors
Supercritical Fluid Technologies introduced a new series of stirred reactors for high-pressure chemistry. The HPR Series Reactors have been designed for researchers who are interested in performing pressurised chemical reactions in their laboratories. Whether it is high- pressure chemical synthesis or process development, the HPR Series is an excellent unit for those applications.
The reactors range in size from 50ml to 4 litres and may be operated up to 10,000 psi and 350°C. The reactors have a magnetically coupled impeller for optimal mixing. All high-pressure components are ASME rated and protected by a rupture disc for safe operation. These laboratory bench top models are ideal for applications where repetitive use makes convenience a necessity, such as catalytic studies, polymerisation, hydrogenation, oxidation, isomerisation, and dehydrogenation. All sizes are supplied as ready-to-use instruments requiring only utility connections prior to operation. The reactors are compact instruments that fit easily into a fume hood. Their modular design makes it simple and cost-effective to alter the unit’s basic configuration to adapt to new or evolving application needs.
All functions for the HPR Series Reactor are controlled by choices of two integrated processors (RxTrol Jr. or RxTrol Sr.) with a full colour touch screen. RxTrol Jr. consists of (2) temperature sensors (wall/interior mounting), and fuzzy logic PID temperature controls and mixing controls in a table top assembly. RxTrol Sr. offers many more advanced features utilising a microcontroller to perform all PID, ramp/soak, process trending, and interlock functions.
Additional options include vessel windows (<150°C operation only), additional ports, cooling coils, sample loops, stand alone pressure transducers, supercritical fluids pumps and reagent addition modules.

“Pittcon was outstanding for us this year. We had so much booth traffic that I had almost lost my voice after two days.”
Craig Prater, CTO, Anasys Instruments
“The show went really well, Pittcon attendance is a must, absolutely. We had important new contacts and were able to follow up with important contacts that are going to invest in the near future. We pick up new information about the business and get important information from users in the industry, information that they may not want to put in writing. Direct contact is always better and what better place than Pittcon, the leading international exhibition in the industry. Attendance was of course down relative to the last year, but Orlando is always lower. We really look forward to having Pittcon in Atlanta and Philadelphia as well, taking advantage of getting visitors from those important regions, visitors who may not be allowed to travel for more than one day, but will now be able to visit Pittcon nevertheless. This will improve the number of contacts that we as an exhibitor get at Pittcon. Having customers come to us for four solid days instead of us having to travel all over the nation and the world to see them is a real benefit and a wonderful thing to experience - every time.”

“Pittcon has been and remains a very important event for Buchi. With our product range covering a full spectrum of applications, from sample preparation to NIR spectroscopy, this show represents an unparalleled venue for meeting our many varied customers and prospects. For a company like ours, with new products launches every single year, Pittcon’s yearly frequency is ideal. Even though these days Pittcon is different from what it was 10 years ago, in 2010 we achieved our show objectives and are looking forward to returning again next year.”
