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.
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.
Retsch has published a new 36 page general catalogue covering the complete range of crushers, grinders, sieve shakers, particle analysers and sample dividers. Each instrument is presented with its main features, technical details and a range of suitable applications. Also included is a complete line of product-related brochures which resent the mills and sieve shakers in greater detail.
Testing for “designer drugs”, “legal highs” and other novel materials is a continuing challenge for clinical, forensic, sports testing and toxicology laboratories. A recent meeting highlighted a number of materials required for use as reference compounds and internal standards in applications such as testing for evidence of exposure to alcohol and drugs in substrates including blood, urine and hair. LGC Standards has announced that many of these new materials have now been sourced and are included in their recently revised and relaunched catalogue, Reference Materials for Clinical, Forensic and Sports Drugs Applications. Many new reference standards, including deuterated materials, glucuronides and other metabolites, are now available to laboratories carrying out analysis for drugs of abuse, therapeutic drugs and sports doping agents.
Alfa Aesar has published a new brochure entitled Fine Chemicals and Catalysts, which explores the fine chemical production and service capabilities provided by the company. The 16-page brochure begins by outlining their key capabilities, including global manufacturing, global inventory, custom synthesis, customer service, quality control and global sourcing. The product offering is then examined in more detail to encompass organic intermediates and reagents, precious metal compounds and catalysts, including fuel cell products and high purity inorganics, including Puatronic high purity inorganics and REacton rare earth products. The brochure also covers additional resources provided by the company, such as a 2800-page catalogue/handbook accompanying CD-ROM, website, technical sales and support. The brochure is available from the company free of charge.
