7 High Performance Single and Triple Quadrupole Mass Spectrometry to Gas Chromatographers
Bruker has announced the release the SCION TQ™ triple quadrupole and the SCION SQ™ single quadrupole mass spectrometers for gas chromatography (GC) detection. Designed especially to enhance data quality and productivity for analysts working in routine testing and applied markets, these systems combine performance and value like never before in GC-MS. The SCION GC-MS platform offers revolutionary performance and ease of use, particularly for the food safety and environment monitoring communities, and represent an innovation leap in GC-MS technology.
The SCION series features the industry’s first ion ‘lens-free’ technology, which makes these systems very easy to use, regardless of the level of mass spectrometry experience of the operator. The new SCION series is also significantly more sensitive and robust than previous GC-MS instruments, and comes in a very compact bench space saving footprint that is far smaller than for conventional GC-triple quadrupole MS systems.
The advanced axial source design, combined with the unique ‘lens-free’ ion path also significantly enhances the overall robustness of the SCION series. The SCION TQ also incorporates a 180-degree collision cell design for a dramatically smaller instrument footprint; a critical need in emerging markets and for anyone choosing to upgrade their GC-MS technology.
Further enhancing the exceptional performance and value of the SCION TQ is Bruker’s innovative and unique Compound Based Scanning (CBS) technology. Ideal for the automation and optimisation of quantitative analytical methods, CBS allows users to achieve high levels of sensitivity and quantitative precision while greatly reducing methods development and instrument set up time. By simply selecting the compounds from the compound library to add to the method editor, the unique CBS technology and expert software automatically sets up optimised MRM transmissions, and calculates the optimum cycle time, at a fraction of the workload for the method’s developer.
The SCION SQ has been designed for extensive routine usage and shares many of the design innovations of the SCION TQ. This includes a plug- and-play source for simple maintenance, or easy conversion from EI to CI operation. The new axial flow source improves systems performance, and lengthens the time between maintenance, even when handling today’s challenging matrices.

Identification of King Henry IV’s Head
Known as ‘the good king Henri’ or ‘the green gallant’, Henry IV was one of the most favourite French kings. After his assassination by a religious fanatic named Ravaillac in 1610, Henri IV was buried alongside France's other kings in the Basilica of Saint Denis. Since the profanation of the graves by the Revolutionists in 1793, the head of his embalmed body disappeared and was conserved in successive private collections. In January 2010, the embalmed head was rediscovered and a group of scientists led by Philippe Charlier, from the Raymond Poincaré University Hospital, attempted to confirm its identification using multiple scientific techniques. HORIBA Scientific was involved in this fascinating study for its expertise in spectroscopic techniques.
Micro X-Ray fluorescence analysis has particularly revealed the elemental composition of a small grey mineral substance present only on the face skin. The major elements found (silicon, aluminium, iron, titanium and potassium) constitute a typical composition for clay that confirms the realisation of a mould of the face at the end of the 18th century.
Moreover, analyses using a LabRAM ARAMIS Raman microscope help to identify the black substance present at the base of the royal neck as Ivory Black (a variety of amorphous carbon). This charcoal, obtained by anaerobic calcinations of animal bones, is known (through sixteenth century medical journals) to have been used by the King’s surgeon to absorb decomposition fluids and putrefactive gas.
These results associated with the ones obtained by radiocarbon testing and embalming procedures knowledge provide valuable evidences that the embalmed head belongs effectively to Henry IV.
