February / March 2012 Making the Transition From SQ to TQ GC-MS Easier
Bruker Chemical and Applied Markets, has published a new article authored by experts from Bruker’s Chemical and Applied Markets division on how Gas Chromatography (GC), coupled to a triple quadrupole Mass Spectrometer (GC-MS/MS-QqQ) operated in MRM mode, is rapidly becoming the preferred technique for multi-residue analysis in complex matrix samples by analytical laboratories.
Transferring from the single quadrupole to a triple quad can present potential difficulties for the chromatographer who may not necessarily be an expert in mass spectrometry. Bruker has introduced an innovative user- friendly solution to this transfer with its proprietary Compound Based Scanning (CBS) software in the company’s new SCIONTM TQ system.
Major advantages of CBS is that the new work flow focuses on compounds and not each MRM. The MRM transition of an analyte does not need to be known by the user. Software auto-fills information from a factory installed read-only compound library that contains over 2,500 MRM transitions for
more than 900 common contaminants. CBS then sets up the method and manages the TQ duty cycle during analysis and data acquisition. Compounds in the library are linked to retention time, primary and secondary MRM transitions, and collision energy. Using CBS dramatically reduces the time taken to set the initial MRM methods, improving workflow and productivity.
Analysis of pesticides in vegetable matrix using Bruker’s SCION TQ GC-MS/MS illustrates the use of CBS for developing an MRM based method to analyse 258 pesticides (516 MRMs) dramatically reducing the time taken to set the initial MRM methods for accurate data.

ExcelTM Ultra Robust UHPLC New Multimedia Guide «IC UHPLC
Maintenance» Available Now Ion chromatography has become the method of choice for many applications. Sensitive as it is, correct results depend crucially on the correct use and
maintenance of the IC instrument. To this end, Metrohm has published «IC Maintenance», a new multimedia guide demonstrating users of Metrohm IC how to carry out essential maintenance work on their IC system by themselves. «IC Maintenance» is free of charge and can be ordered from any Metrohm representation.

Short videos guide the users step by step how to perform maintenance work correctly on Metrohm IC systems. In this, the new multimedia guide takes a systematic approach. It starts with IC handling in general (cutting capillaries, PEEK pressure screws, starting the IC system …), after which the maintenance of each functional component (Eluent, high-pressure pump, inline filters, injector, columns, etc.) is demonstrated. Information about correct liquid handling round off «IC Maintenance» and FAQs and a glossary make the new multimedia guide very easy to use.
«IC Maintenance» is a must for anyone who wants to perform essential maintenance on his Metrohm IC by himself. Moreover it can be used as a tool in teaching IC maintenance to students.
