Scope of the presentation

• Introduction
• Potential Impacts of the 4th 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: 1784 (steam, water, mechanical production equipment) Revolution 2 – Year: 1870 (division of labour, electricity and mass production) Revolution 3 – Year: 1969 (electronics, IT and automated production) Revolution 4 – Year: ???? (cyber-physical systems), Klaus Schwab in 2016

Potential Impacts of the 4th Industrial Revolution

• Automation
• Semi-automated data management (capturing and manipulation) versus

fully automated data management (capturing and manipulation)

• Technological advancement
• Manual laboratory activities versus automated activities.
• Laboratory infrastructure
• Environmental control where manual thermometers are used versus

automated environmental control.

• Country economical development level
• 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-)

• Potentiometric method (auto-titration)
• 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)
