Mass Spectrometry & Spectroscopy 17 Product Portfolio Expanded with Launch of ICP-OES


Within its core segment for analysis measuring technology, Analytik Jena AG now offers with the PlasmaQuant®


PQ 9000 its first High-Resolution


Array ICP OES (optical emission spectrometry using inductively coupled plasma) for multiple element analysis as part of its own technology portfolio. This method is routinely used for determining smallest element concentrations especially in environmental analysis, material research, metal or pharmaceutical industries.


“The PlasmaQuant® PQ 9000 has been developed to master the most


complicated analytical challenges in emission spectroscopy with the highest degree of precision, method flexibility and operating comfort. In doing so, we are building on our longstanding experience in the development of high-end spectrometers,” said Torsten Olschewski, Head of the Analytical Instrumentation business unit at Analytik Jena AG.


Technological advances in the product include the optical resolution, the plasma torch design and the generation and observation of the plasma.


PlasmaQuant®


PQ 9000 offers: clever bench-top design; innovative high-end technology; impressive analytical performance; high sample efficiency; benchmark-setting operating comfort; premium quality ‘Made in Germany’.


PQ 9000 also allows for the safe analysis of rare earth metals such as cerium, lanthanum, neodymium or samarium in silicate-containing minerals. The high salt contents in these minerals (silicates) are not a problem thanks to the technology of the PlasmaQuant®


The PlasmaQuant® PQ 9000 system. Spectral interferences caused by the high contents of these samples of main group elements such as sodium, aluminium or silicon can be detected with the help of high resolution and easily corrected.


Another application is the analysis of biodiesel for traces of metals such as sodium, potassium or manganese. These lead to foaming of the fuel and thus to unstable or lower performance as well as clogging of filters. Other trace elements to be controlled are phosphorus and sulphur, which are known as catalyst poisons. In addition, the sulphur r dioxide produced during combustion is an environmental pollutant.

The new Hiden Analytical Overlap Evaluator for Android & iPad is a reference tool for users of mass spectrometers operating in the fields of vacuum science and vacuum processing, and for advanced researchers using real time gas analysis systems. The evaluator enables the user to create a mass spectral overview of multiple fragmentation spectra to identify the mass peaks with least spectral interference and therefore most suited to species monitoring, and includes a quick mass peak look up table from a library of common gas and vapour species.


The MS spectral overlap evaluator for Android is available free from the Google Play Store http://tinyurl.com/ HidenMSEvaluatorAndroidApp.


28411pr@reply-direct.com ADVERTORIAL The Photonis Spiraltron™ Family of Miniaturised Channel Electron Multipliers


Single channel electron multipliers (‘Channeltrons’) offer exceptional amplification properties with unsurpassed low noise behaviour, but traditionally these detectors have been restricted to high vacuum environments. The ability to expand the use of these types of detectors to high pressure applications provides an opportunity for weight, cost, and power reduction for existing instrumentation. Further, it may serve as an enabling technology for applications where low signals need to be measured at high pressure, such as in portable instruments


The Photonis Spiraltron™ family of miniaturised channel electron multipliers can deliver high performance at pressures to 10-2 from a common collector cone. This cone shape can be configured to meet the specific instrument or application – round, square or rectangular.


torr. A Spiraltron™ detector consists of six individual channels fed


The spiral section of the detector consists of six single channels which are twisted, barber pole fashion, around a solid centre. The multi-channel configuration provides a six-fold increase in surface area compared to single channel electron multipliers, leading to longer life performance. The internal spiral structure enables low noise performance by significantly reducing the ion feedback typically generated from the high concentration of residual gas molecules in high pressure environments. The number of turns per inch can be varied to shorten or lengthen the overall ion path.


The internal twisted ion path design of a Spiraltron provides an on-axis design in a compact size for a simple plug-and-play replacement. The detectors offer high dynamic range and low life, since the extracted charge comes from six individual channels that delay the onset of saturation. The internal spiral architecture reduces ion feedback, allowing for operation at pressures to 10-4


torr. Spiraltron™ detectors operate at elevated pressures into the 10-4 torr range, a factor of 10 above traditional CEMs and discrete dynode multipliers. Spiraltron™ electron multipliers are ideal for applications requiring high linearity. In addition, they provide excellent single ion sensitivity, producing Gaussian pulse height distributions (PHD). A new App for Mass Spectrometry


For applications requiring sensitive detection in higher pressure, the MegaSpiraltron™ detector is a physically small, robust ion detector that can achieve high gain while maintaining low noise. These detectors have a compact, durable design and are only 1.35” long and 0.6” in diameter. MegaSpiraltrons can operate at 10-2 torr making them an excellent choice for portable instrumentation or poor vacuum.


Finally, the MAGNUM™ electron multipliers provide high dynamic range with high gain and low noise. The single piece cartridge design allows easy integration and replacement. MAGNUM™ detectors are available for analogue or pulse counting applications, with standard or extended dynamic range performance. They can be operated at pressures 7x10-4
