Glass Expansion has announced the availability of their new 2009 catalogue. This catalogue is a reference for all ICP-OES and ICP-MS users and includes many components covering over 50 current and past ICP-OES and ICP-MS models from all the major manufacturers. The 96 page full-colour catalogue includes nubulisers, spray chambers, torches, RF coils and ICP-MS cones by instrument model, plus general consumables and accessories such as the new TurboFlo monitor. It shows the optimum combination of sample introduction components for most sample types, including aqueous and organic samples, samples with high dissolved solids or particulates, limited sample volumes or samples in HF.
The new Techne catalogue introduces new cooling products and the company's extended thermal cycler range. Over 50 full colour pages illustrate their temperature control and science equipment for life sciences, research, clinical and general laboratories. Two significant additions in the new catalogue will solve sample-cooling problems in many labs. The N°ICE electronic ice bucket contains ceramic-coated beads to support any shape vessel and the BL°CKICE cools tubes held in two Dri-Block inserts. Both maintain a set temperature in the 0°C to 40°C range. Their range of personal thermal cyclers is joined by the expanded capacity TC-3000X and the TC-3000F, a small gradient model. Users of standard thermal cyclers will welcome the appearance of the new-look TC-4000 and TC-5000. Also included in the Techne range are temperature-controlled water baths, Dri-Block heaters, cell culture equipment and molecular biology products such as hybridisation incubators.
The latest edition of the CAM AG Bibliography Service, CBS 102, is now available from their UK distributor Omicrom Research. This latest issue features CAM AG's new TLC-MS interface, showing how its semi-automatic design can aid the identification of unknown substances by extracting compounds from a TLC/HPLC plate and feeding them into a mass spectrometer for substance identification of structure elucidation. Botanical slimming products come under investigation using HPTLC methods, revealing the extent to which Hoodia Gordinii is misrepresented in product labelling. Studies of nature continue with HPTLC analysis of natural sponges and the world's oldest tree species, Ginko Bibba, for their pharmacobiological properties.
The first comprehensive Jenway catalogue has now been published, with over 90 colour pages giving full technical details and ordering information. Complementing the launch of a new website, the catalogue includes details of several additions to the spectrophotometer range. The 6315 is an advanced measuring system using a pulsed xenon lamp, the 6800 is a true double-beam instrument which includes Jenway Flight Deck software and the novel user interface and operating system of the new 67 series spectrophotometers offer simple intuitive operation.
Axiom Analytical has announced the availabilty of a new technical note, A Beginner's Guide to Spectroscopic Analysis for Industrial Applications, which is intended to serve as a brief introduction to the diverse forms of molecular (or vibrational) spectroscopy as applied to both process development and on-line process applications. It provides a brief introduction to mid-IR, NIR, UV-vis and Raman and discusses sampling methods applicable to each. One table compares the attractiveness of each in light of the band type involved, calibration methods, optical materials, availability of fibre-optics, sample fluorescence, background radiation, references and cost of ownership. A second tables summarises the applicability of the three major forms of molecular spectroscopy to specific sample types and a third tables assesses the applicability of each form of spectroscopy to clear liquids in the light of a variety of considerations such as the need for in situ sampling, high temperatures and pressures, corrosive samples, the need for functional group specificity, rapid survey, short production runs, thermal background, availability of an internal reference and cost of ownership. A final section reviews the conditions favouring extractive vs in situ sampling.
