For many years chemical measurement has remained the preserve of the analytical chemist. In recent years, however, on-line analytical measurement has become an integral part of process control measurement and is increasingly becoming the responsibility of the instrumentation and control technologist. As a result, working knowledge of analytical measurement is now a prerequisite for efficiency in the workplace. Unfortunately, schoolboy chemistry provides few people with the skills required for the rigors of analytical chemistry as applied to on-line process control. In modern laboratories, there is an increasing need for analyst to understand and be able to quantify the performance of analytical instruments, in particular with respect to the following:
- specify equipment for purchase
- estimating uncertainties in instrumental measurements
- quantifying and demonstrating performance quality
This training program on analytical instrumentation is specifically tailored for engineers and technicians working within industry who do not have a chemical background and has been designed to take the mystery out of analytical measurement and explain it in terms that are easily understood by the beginner.
Upon successful completion of this course, the delegates will be able to:
- Analyze the instrument performance characteristics which include types and interaction between
- different characteristics
- Prepare and handle sample for different analytical instrumentations
- Define what are the pH measurement, measurement of redox, and conductivity measurement
- Explain the dissolved oxygen measurement, installation and troubleshooting and chlorine measurement
- Describe the vapor pressure, relative humidity, sling psychomotor, mirror system and hydrometric
- calculations
- Apply the basic principles of infrared spectroscopy and gas chromatography
- Gain more knowledge after practical session
