Gas chromatograph offers expanded choice

ABB has expanded its process analyser offering for chemical, oil and gas applications with the introduction of the new PGC1000 field-mounted process gas chromatograph. Suitable for measurement of

hydrocarbon groups C1 to C9+, inerts and hydrogen sulphide, the PGC1000 provides a compact measurement solution for a wide variety of gas processing applications. Measuring just 16 inches front

to back and weighing 28 pounds, the PGC1000 offers a highly compact footprint, opening up new installation possibilities. The single module contains all of the necessary switching valves, columns and detectors, with no metal moving parts. As a field-mounted device, it can be

installed outside near to the sampling point and can be used in temperatures from -18°C up to 55°C, or -40 to 55 where a cold weather enclosure is used. The device can be fitted either directly onto two or 12 inch pipelines or onto a pole if required. The PGC1000 provides a choice of sampling options. Up to four different gas streams can be sampled at a time. Users have the option of a single auto calibration stream and three sample streams or two auto calibration streams

and two sample streams. A standard sample conditioning module is also supplied to handle gas streams that need additional filtering or where sample transport lag times need to be minimised. A key feature of the PGC1000 is its

ease of use, enabling it to be used by operators with little or no experience of using process gas chromatographs. Programming and operation is achieved via a graphical user interface software package on a laptop or workstation PC.

Combining a Windows-based interface with a program specially written for the PGC1000, the software provides a simple yet powerful tool for operations, diagnostics and data handling. The PGC1000 retains historical

data which can be subsequently used for audit trails, maintenance and troubleshooting, including verifying transmitter operation. Via the operator interface, users can configure the period for which data needs to be retained. The default memory configuration

ICP-QQQ named best new spectroscopy product

Agilent Technologies Inc’s 8800 Triple Quadrupole ICP-MS (8800 ICP-QQQ) has been named Best New Spectroscopy Product in the 2012 Scientists’ Choice Awards. Introduced early last year, the 8800 ICP-QQQ is the only instrument of its kind,

providing superior performance, sensitivity and flexibility compared with single quadrupole ICP-MS technology, and delivering consistent and reliable results even when sample composition is complex or variable. SelectScience , an independent, member-based online publication serving

scientists and industry professionals, presented the award to Agilent representatives last week at the Pittcon Conference and Expo in Philadelphia. The annual Scientists’ Choice Awards give SelectScience members the opportunity to vote for their favorite products and services. “Every year, the Scientists’ Choice Awards celebrate the new laboratory products

and equipment making a real and meaningful difference in the work of scientists who serve a variety of industries,” said Kerry Parker, editor and general manager of SelectScience. In 2010, the Agilent 1220 Infinity LC system received the award for Best New Separations Product. In 2009, the Agilent 6430 Triple Quadrupole LC/MS system was

voted Best New Spectroscopy Product. “We are very pleased to learn that scientists from all over the world are

experiencing the benefits of this revolutionary new ICP-MS instrument,” said Philip Binns, Agilent vice president for spectroscopy products. “The 8800 provides improved performance and flexibility in a variety of important applications, including semiconductor manufacturing, advanced materials, clinical and life sciences, and a wide range of research and routine applications where problematic interferences can hamper the capabilities of conventional ICP-MS technologies.” The Agilent 8800 ICP-QQQ is the flagship product in the company’s portfolio of

ICP-MS hardware/software solutions, which includes the Agilent 7700 Series ICP-MS, the benchmark for high-performance quadrupole ICP. The configuration of the Agilent 8800 ICP-QQQ enables MS/MS operation,

providing precise control of reaction processes in the ORS3 collision/reaction cell. MS/ MS mode controls the ions that can enter the cell, delivering consistent and reliable results even when the sample composition is complex or variable..

enables the details of up to 480 analysis cycles to be stored, including parameters such as temperature and pressure, noise values and alarms. This data can be collected either via a remote communication link or via the laptop or workstation interface. Basic data can also be accessed

via the PGC1000’s ¼-inch VGA display screen. Via this display, the user can perform many of the operator functions without the use of a laptop or PC. Magnetic interface technology enables the user to handle basic programming tasks through the PGC1000’s explosion-proof glass, eliminating the need to open up the device and compromise its safety protection. Maintenance is also simplified.

Both the PGC1000’s hardware and software feature easily replaceable electromechanical modules, making the unit simple to repair or upgrade. Diagnostic software and wizards also make it easy to trace any faults. The PGC1000 is fully certified to

leading safety standards, making it suitable for use in a range of potentially explosive and hazardous areas.
