IN FOOD EMBRACE TESTING THE 4 TH LABORATORY INDUSTRIAL - PowerPoint PPT Presentation

IN FOOD EMBRACE TESTING THE 4 TH LABORATORY INDUSTRIAL _________________________ REVOLUTION Presenter: Mr Ephraim Moruke Date: 14 November 2018

Scope of the presentation • Introduction • Potential Impacts of the 4 th Industrial Revolution on Laboratories • Testing techniques – methodologies • Food for thought - considerations

Introduction • Fourth Industrial Revolution – “a new era that builds and extends the impact of digitization in new and unanticipated ways” (Davis, 2016). Revolution 1 – Year: Revolution 3 – Year: 1784 (steam, water, 1969 (electronics, IT mechanical production and automated equipment) production) Revolution 2 – Year: Revolution 4 – Year: 1870 (division of ???? (cyber-physical labour, electricity systems), Klaus and mass Schwab in 2016 production)

Potential Impacts of the 4 th Industrial Revolution • Automation v/s - Semi-automated data management (capturing and manipulation) versus fully automated data management (capturing and manipulation) • Technological advancement v/s - Manual laboratory activities versus automated activities . • Laboratory infrastructure - Environmental control where manual thermometers are used versus v/s automated environmental control. • Country economical development level v/s - Laboratories from developing countries are mostly focused on labour intensive manual methodologies versus laboratories in developed countries employing a higher percentage of automation i.e. instrumental analysis.

Testing techniques - methodologies • Mohr method (argentometric titrations) - Most affordable method, unable to distinguish between different sources of the determinant (Cl - ) Chemical Reaction of Mohr Method • Potentiometric method (auto-titration) Source: www.BCLearningNetwork.com (Colgur, 2014) - Fairly affordable method, can handle reasonable number of samples but still will fail to distinguish different sources of the determinant (Cl - ) • Elemental analysis (Inductively Coupled Plasma Optical Emission Spectrometer, ICP-OES) - Expensive method, very selective and accurate thus also can handle large sample numbers

Food for thought - considerations • Competitiveness of the laboratory - Investment in instrumentation (preferably fairly recent technologies) - Infrastructure (environmental controls and proper IT platforms) - Training/retraining of personnel to be competent with recent methodologies - Quality costs (participation in Proficiency Testing schemes, continuous improvement, maintenance of the quality management systems)
