Chromera chromatography data system for LC now includes PhotoDiode Array (PDA) detector control and 3D analysis. With real-time display of multichannel chromatograms and 3D contour graphics, Chromera provides an ideal solution for LC PDA analysis and also allows for peak integration, sequence generation and comprehensive reporting.
Termo Fisher Scientific took the opportunity to announce the new Termo Scientific ISQ single quadrupole gas chromatography- mass spectrometry (GC-MS) system with a novel, non-venting full-source removal capability (Fig. 3).
Featuring the new ExtractaBrite ion source, the ISQ system offers simplified operation and maximum uptime for uninterrupted productivity across routine GC-MS applications including forensics, toxicology, food safety and environmental. Te ISQ GC-MS is a highly robust and rugged system that provides high-throughput sample analyses and 24/7 operation.
Te new ExtractaBrite removable ion source is designed to provide maximum uptime and productivity by extending the length of time between required source maintenance. When the system requires maintenance, the time- consuming and labour intensive

procedures including breaking the vacuum, cooling off, cleaning, reassembling and restoring associated with conventional systems are eliminated. Te entire ion source can be removed without venting the analyser. Te new ISQ single quadrupole GC-MS also offers an extended mass range, from 1.2 to 1100u, for analyses across a varied range of compounds.
Termo Fisher says the ISQ system is ideally-suited for today’s fast-paced gas chromatography methods. Advanced electronics allow the ISQ to acquire and write data to disc at accelerated rates for truly high-speed acquisition in real-world applications. Te sequential full scan/selected ion monitoring (SIM) capability provides qualitative and quantitative analyses in a single injection, for confirmation and screening in the same analytical run.
YMC used the event to launch its Triart C18 hybrid HPLC column and bulk packing. Te layered hybrid structure of the YMC-Triart C18 particle results in a material with very high chemical and physical durability. It can be used at any pH from 1 to 12 and may be used at elevated temperatures, too.
YMC-Triart C18 was developed utilising YMC experience in microreaction chemistry. Te resulting uniformity and quality
of the particles contribute to the chromatographic performance of the finished product. Excellent peak shape for all types of compounds results from YMC’s use of a multi- reagent, multi-step, endcapping process that renders ‘neutral’ the analyte accessible residual silanol sites. Te advanced end-capping process improves overall peak shape. Te physical and chemical durability, precision granulation, and advanced end-capping of YMC-Triart C18 combine to produce a reversed phase material that is durable and
versatile and exhibits benchmark column-to-column and lot-to-lot reproducibility typical of YMC HPLC columns.
YMC-Triart is available in 3 and 5µm particles, with a pore size of 120 Å. Additonal chemistries are also available in prep particle sizes (10 micron and greater) on a custom basis for customer specific applications.
Alpha MOS’s new database for aroma and chemical characterisation by gas chromatography analysis, AroChemBase, includes 2900 compounds. For a selected peak on a chromatogram, the library proposes a list of possible compounds. To facilitate identification, the compounds are sorted based on a unique recognition accuracy index. Tis index is based on the comparison of measured parameters (retention time, peak area on one or two columns) and theoretical ones. Te higher the index, the higher the probability of correspondance. Te specificity of this library is to provide the sensory attributes linked to a chemical compound, which makes it suitable for quality control or R&D applications with sensory considerations.
