Isohumulones starter kit. As the starter kit provides all of the consumables, analysis can be started immediately.


Te company cites a number of advantages to the on-line sample preparation approach: it speeds up and automates labour- intensive sample clean-up and enrichment processes, making direct injection of untreated samples and unattended 24/7 operation a reality; the beer sample can be injected without any sample preparation; and the workflow completes the analysis in nine minutes as compared to one hour needed by off-line SPE- HPLC analysis.


Quick wine analyses Te RX Monaco analyser from Randox Food Diagnostics is now validated for use on wine. With the company’s semi-automated RX Monza analyser already widely used throughout the industry, the firm recognised that medium-to-large producers could benefit from a quicker turn-around and economies of scale offered by a fully-automated system. As a supplier of a full range of analysers within the RX series, Randox identified the Monaco as a cost-effective solution with a throughput appropriate to a broad spectrum of wineries’ needs. A key benefit with Monaco is that producers can test for the full range of parameters including


For larger producers the accuracy of the Monaco means it is also appropriate to be used as a corroboration application for systems already in place.


Randox is also helping to tackle international trade disputes by meeting the demand for beta-agonists diagnostics. For example, meat producers in the USA and Brazil have experienced difficulties exporting to Chinese, Russian and European food markets because of the level of beta agonist veterinary drugs in meat - particularly Ractopamine and Zilpaterol.


Beta-agonists are a group of drugs that act on b-adrenergic receptors and are used in veterinary and human medicine to treat cardiovascular and breathing disorders. Commercially, beta agonists are used to increase muscle growth and decrease fat deposition in animals.


malic acid, glucose/fructose and ethanol from a single sample, increasing efficiency and cutting the cost per test.


With direct application and no sample preparation requirements the system reduces time and labour costs, bringing the overall cost per test down to circa €0.35 as well as producing a result every few seconds.


High demand is anticipated from wineries in remote locations that currently send results off- site to central laboratories and then experience several days’ turnaround. Cutting out these delays means that winemakers and laboratory technicians can make the appropriate adjustments to processes immediately, improving overall quality of the wine.


Zilpaterol is a powerful beta adrenergic agonist that has been developed as a growth promoter for cattle leading to enhanced weight gain and carcass yield. Of particular concern is the use of beta agonist drugs prior to slaughter as this poses a risk to the human health if contaminated meat enters the food chain.


In response, Randox has released Zilpaterol testing products on both ELISA and biochip array


Phenomenex publishes comprehensive food safety applications guide F


ood consumption is a necessity for everyone. In compliance with the CODEX ALIMENTARIUS guidelines methods of analysis should be reliable,


display intra-laboratory repeatability as well as inter- laboratory reproducibility, be selective, sensitive, and should have proper limits of detection/quantification. Now Phenomenex, a global leader in the research


and manufacture of advanced technologies for the separation sciences, has published a 92-page Food Safety Solutions guide. Available in print and digital format, the guide presents 41 complete applications for all of the frequently requested food compound


classes and draws on all analytical techniques – sample preparation, HPLC, UHPLC, LC/MS and GC/MS. The guide highlights methods created through


Phenomenex’s Rapid Response Unit collaboration with AB SCIEX, including iMethod Applications for Cliquid software. Phenomenex’s complete line of solid phase extraction (SPE) sorbents and QuEChERS and filtration products are also highlighted. “Concern for food safety is on the rise globally,


creating the need for analysis of a wide range of imports and exports,” explains Allen Misa, brand manager for Phenomenex. “We offer a comprehensive selection of


solutions for the analysis of food substances, along with application support and method development services through our PhenoLogix team.” The new Food Safety Solutions guide contains


sections on the analysis of contaminants, pesticide residues, allergens and fraudulent practices. A section on veterinary medical products is also included. Phenomenex itself offers solutions for screening


and confirmatory methods for a variety of hazards including mycotoxins, environmental and process contaminants, food contact materials, pesticides and veterinary product residues, and allergens.
