Techniques or activities of Analytical Chemists vary depending on the employer or area of specialization. However, essentially, they analyse samples from various sources to provide information on compounds or quantities of compounds present. They employ analytical techniques and instrumentation, such as gas and High-Performance Liquid Chromatography (HPLC), Ion Chromatography, Electro-Chromatography and Spectroscopy (infrared and ultraviolet, among others).

Energy Managers plan, regulate, and monitor the energy use in an organisation or facility. They coordinate all aspects of energy management, from reduction of carbon dioxide emissions, to waste management and sustainable development by encouraging the use of renewable and sustainable energy resources within an organisation or community. Also, they develop solutions for carbon management, and raising the profile of energy conservation.

Manufacturing Engineers are both designers and analytical and creative thinkers. Their job role involves improving the process of producing high-quality goods efficiently using the most cost-effective methods. They work towards the aim of reducing the impact of production on the environment.

Their expertise lies in understanding the properties and behaviors of different substances, from raw materials to finished products.

Mining Engineers manage and oversee mining production processes, and are involved in the final closure and rehabilitation process.

The scope of the job of Production Managers depends on the nature of the production system. Organizations involved in several types of production add to the complexity of the role. They are responsible for overseeing both human and material resources.

Quality Managers are responsible for monitoring and advising on the performance of the quality management system, producing data and reporting on performance, and measuring finished products against set standards of manufacture.

Chemical Engineers are involved in the design and development of a diverse range of products. Their work focuses on changing the chemical, biochemical, and physical states of substances to create new products, such as plastic from oil. They work in a variety of industries including Energy, Food and Drink, Oil And Gas, Pharmaceuticals, Plastics, Toiletries, Water Treatment, and such.

Energy Engineers are focused on finding efficient, clean, and innovative ways to supply energy. They work in a variety of roles including designing and testing machinery, and developing ways of improving existing processes. Also, they research and develop ways to generate new forms of energy, reduce emissions from fossil fuels, and minimise environmental damage.

Process Development Scientists are responsible for optimizing the performance of manufacturing systems. They typically identify and develop new processes for product manufacture, and implement process control mechanisms to make sure that the finished products are of high quality and are manufactured in a reproducible manner. They also develop and improve existing products.
