Health scares and regulations drive analysis developments
Public health scares and tougher regulation are, as Sean Ottewell finds out, helping to boost spending in the food and drink laboratory science sector.
Selon une découverte de Sean Ottewell, les crises de la santé publique et la règlementation plus stricte contribuent à l’augmentation des investissements dans le secteur Aliments et boissons des sciences de laboratoire.
Ängste um die Gesundheit und strengere Bestimmungen sorgen für höhere Investitionen in die Laborwissenschaft der Lebensmittelindustrie, wie Sean Ottewell ermittelt.

ew from Termo Fisher Scientific is an efficient high-performance
liquid chromatography (HPLC) method using ultraviolet (UV) detection for the simultaneous determination in drinking water of all 19 phthalate compounds listed in key environmental regulatory documents.
A research document, Determination of Phthalates in Drinking Water by UHPLC with
UV Detection, demonstrates that the phthalates listed in European Union Directive 2005/84/EC, US Environmental Protection Agency Methods 606 and 8061A, the Chinese HJ/T 72- 2001, and the Standardisation Administration of China GB/T 20388-2006 and GB/T 21911- 2008 are well separated on a reversed-phase HPLC column in less than 25 minutes.
Phthalates are a class of chemical compounds widely used as plasticisers for polyvinyl chloride resins, adhesives, and cellulose film coating. Tey are potentially hazardous to human health - especially to children’s health - due to their classification as endocrine disruptors. Tis has resulted in regulations regarding the types and levels of phthalates allowable in plastic toys, water containers, textiles, and foods.
In a separate development, the company has also released Total Solutions for Isohumulones in Beer, a robust, user-friendly, and fast on-line, SPE-UHPLC method that improves the traditional off-line SPE-HPLC analysis of these chemicals.
Isohumulones (iso-α-acids) form approximately 80 per cent of the typical bitterness of beer. Teir antimicrobial effect leads to a sterile beverage, their tensioactive character stabilises the foam, and they have a major influence on the general flavour, smell, and smoothness of beer.
HPLC represents the only analytical method that enables the specific quantitation of iso- α-acids in beer. Total Solutions for Isohumulones in Beer provides the determination and quantitation of all major cis- and trans-isomer variants of iso-α- acids that are present.
Te solution consists of a Termo Scientific Dionex UltiMate 3000 system package and its related Termo Scientific
