Postnova Analytics: Characterisation of Nanomaterials in Foods
Postnova Analytics reports on how the inorganic analysis team within LGC (Teddington, UK) has been using the AF2000 Field Flow Fractionation system coupled to Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to characterise nanomaterials in complex food sample matrices.
Nanomaterials are known to be present in over 1300 foods and commercial products. As a result of the European Union (EU) recently providing a precise definition of a nanomaterial for regulatory purposes, it has become important to be able to characterise nanomaterials reliably to understand their behaviour in contact with humans and the environment.
LGC is an international life sciences measurement and testing company with a history stretching back 175 years, providing reference materials, genomics solutions and analytical testing products and services. It is home to several national government roles, including the UK National Measurement Laboratory, the Designated Institute for Chemical and Bio-measurement and the Government Chemist.

The inorganic analysis team at LGC - led by Principal Scientist and Science Fellow, Dr Heidi Goenaga-Infante - has established world class expertise in size-based and number concentration analysis of nanomaterials using hyphenated techniques to support the development of reference methods and materials, with field flow fractionation coupled to ICP-MS (FFF-ICP-MS) being the centrepiece of their multi-modal analytical approach.
Dr Goenaga-Infante commented “Over the last 15 years, Field Flow Fractionation (FFF) coupled to ICP-MS and other sizing detectors has proven itself a powerful tool for the characterisation of nanomaterials. For complex samples FFF seemed the ideal choice for matrix separation/sample fractionation, enabling us to achieve selective detection and characterisation of nanomaterials, that otherwise would have been hampered by the matrix components”.
Dr Goenaga-Infante added “Having decided that FFF was the technique for us, we approached the two leading FFF manufacturers. We selected Postnova Analytics as our vendor of choice on the basis of their fast response to queries, scientific credibility and knowledgeable technical research assistance. The Postnova AF2000 system works robustly online when coupled with ICP-MS if a systematic approach is undertaken. We very much look forward to extending this collaboration into a partnership for life.”
The Postnova AF2000 is a high performance Flow Field-Flow Fractionation (FFF) platform for separation of nanoparticles, macromolecules and proteins in complex matrices such as foodstuffs. Modular in design, the AF2000 incorporates the combined experience, expertise and technological advances from Postnova Analytics' two decades of leadership in FFF. Incorporating a range of FFF modules in a single integrated system to provide universal separation, the AF2000 offers more flexibility, better performance and more robust results than any system before.
