6 New Spectrometers Redefi ne ED-XRF With Exceptional New Levels of Elemental Analysis Performance
Spectro Analytical Instruments today announced its new line of Spectro XEPOS spectrometers, representing a quantum leap in energy dispersive X-ray fl uorescence (ED-XRF) technology and providing breakthrough advances in the multi-elemental analysis of major, minor, and trace element concentrations.
New developments in excitation and detection introduced with the new Spectro XEPOS ED-XRF spectrometers deliver outstanding sensitivity and detection limits and yield remarkable gains in precision and accuracy. The analysers excel at critical tasks from rapid screening elemental analysis for environmental and waste sampling to demanding applications in research, academia, and geological science. They support precise product quality control at-line for a variety of applications such as chemical and petrochemical production, and the manufacture of cement, cosmetics, food, pharmaceuticals, and more.
The new line of Spectro XEPOS spectrometers features: innovations in adaptive excitation plus tube and detector technologies that dramatically improve sensitivity, often by 10´ or more, to boost precision, realise signifi cantly lower detection levels, and deliver a fast and accurate analysis of a wide range of elements, from sodium to uranium. Enhanced with new high-count detector and tube designs, new sensitivity, and minimised backgrounds, the new analysers’ proprietary adaptive excitation technology enables exceptionally low limits of detection (LODs) for a wide range of elements; unlike most ED-XRF elemental analysers, the X-ray tubes in Spectro XEPOS spectrometers remain powered on between measurements to prevent on/off variations from affecting readings. This ensures long-term stability, realises an exceptionally high degree of precision in elemental analysis, up to 3´ better than before, and delivers substantially improved analytical accuracy for concentrations from trace elements to major components; for operators who require speed more than utmost precision, Spectro XEPOS analysers can dramatically cut measurement times, while still maintaining precision levels comparable to traditional ED-XRF spectrometers. The system’s high speed helps to achieve analyses of most samples within a few minutes.
Redesigned operating software provides proven ease and power, while the unique new TurboQuant II software quickly and accurately analyses practically any unknown liquid, powder, or solid sample.
Optional AMECARE M2M (machine-to-machine) support extends the new analysers’ self-diagnostic functions with proactive alerts, backed up by direct connection with a remote Spectro service expert’s PC.

Report on Benchtop NMR System use by Undergraduate Chemists at Samford University in their Research and Education Programs
Magritek report on the use of their Spinsolve Benchtop NMR spectrometer in the Chemistry Department of Samford University. It is being applied in research in the areas of organic synthesis, reaction methodology and medicinal chemistry.
Dr Paul Wiget is an assistant professor of chemistry at Samford University in Birmingham, Alabama. He fi rst became interested in the Spinsolve instrument when he began interviewing for his current position knowing that his research interests would require a work-around for the lack of a local high-fi eld NMR. Spinsolve, as a two-channel system with indirect-detection, was potentially the answer. The ability to perform 13C, DEPT, HSQC, HMBC experiments was most important. Dr Wiget also saw the scripting function as extraordinarily helpful as it would enable the running of a HSQC experiment and followed by an HMBC routine allowing extraction from the 13C data overnight even when measuring dilute samples.
Dr Wiget describes his array of experiments used in both research and teaching. “We use NMR in our second semester organic laboratory as means to adequately characterise the intermediate and product of a two-step synthesis, an independent project that makes up about two thirds of the students’ grade. We have found that often the carbon channel is most useful in this project due to the inherently low dispersion associated with the proton channel; this is in conjunction with IR, GC-MS, UV-Vis, and melting-point analysis. We also have fl uorescence and ICP atomic absorption available.
“We also use the reaction monitoring function to obtain kinetic data for our physical chemistry course. This is particularly useful because the experiment we monitor is the esterifi cation of trifl ouroacetic acid with various alcohols. With the simultaneous 19F and 1H ‘nested’ monitoring scripts, we can get reinforcing data by monitoring the reaction progress via two nuclei instead of just one. Additionally, when the dispersion issue arises during that experiment, we no longer have to abandon the more substituted alcohols because we can simply monitor the reaction via the 19F spectra.”
Continuing to describe the benefi ts of Spinsolve, Dr Wiget said: “the greatest benefi t of the system is its ease of use and low-level of training for student operation. We are also very fond of no longer needing an air source for spinning. The instrument is very fast and reliable compared to the old, larger, 60 MHz instrument we had.“

High Effi ciency Technologies Provides Superior ICP-MS The superior performance of the PlasmaQuant®
MS from Analytik Jena is achieved through
the synergy of innovative technologies. From the next generation plasma system and dual- cone interface, to the Refl exION’s highly effi cient, 3-dimensional focusing of ions into the high-defi nition quadrupole. They all work together to provide the world’s most sensitive ICP-MS. The simultaneous removal of photons and neutral particles reduces the background to < 1 count, allowing the lowest possible detection limits to be reached.
The ion optics assembly combines the Refl exION ion mirror and a set of extraction lenses that direct the ion beam towards the ion mirror. The parabolic electrostatic fi eld produced by the ion mirror refl ects the analyte ions 90º towards the entrance lens of the pre-quadrupole. Photons and neutral particles are not affected by the electrostatic fi eld and harmlessly pass through the hollow structure to be removed by the vacuum system. By refl ecting the ion beam, complete 3D control of the ion focal point is possible. The benefi t is tunable sensitivity that can be optimised to your specifi c application needs. The intuitive ASpect MS software provides fast, automatic optimisation of all ion lens settings.

Fast and Highly Sensitive N-Glycan Analysis for LC and LC-MS Workfl ows
Waters Corporation have announced a new 24-sample option for its highly acclaimed GlycoWorks™ RapiFluor-MS™ N-Glycan Kit. The new format processes 24 samples, eight at a time, and opens the door further to laboratories that want to begin realising the benefi ts that RapiFluor-MS brings to glycan analysis.
Depending on a laboratory’s sample preparation needs, the Waters® GlycoWorks RapiFluor-MS N-Glycan Kit is now available in either a 24-sample or 96-sample format. The RapiFluor-MS labelling reagent yields enhanced MS sensitivity that is 100 to 1,000-fold greater than current approaches. It also supports a simple, robust protocol for routine laboratory use that incorporates the Waters ACQUITY® mass detector.
