Process Sampling Systems (AAS05)

This lesson introduces participants to the tenets of sound simple handling system design for process analyzers.

Prerequisites

This lesson is designed for participants with an understanding of industrial process control, process analysis, spectroscopic analysis, gas chromatographs, and air and waver analysis. Participants should also have a basic understanding of chemistry and physics.

Description

This lesson introduces participants to the tenets of sound simple handling system design for process analyzers and covers each of the major sections usually included process interface, sample transport, sample conditioning, and sample disposal. Multi-stream switching and contamination prevention strategies are also covered.

Objectives

Identify the reasons for using a sample handling system in process analysis. Identify the importance and characteristics of a well-designed sample handling system. Identify the reasons for using a sample handling system in process analysis. Describe the operating principles of sample handling systems. Recognize sample system components. Identify the materials of construction in different sample handling systems that enable components to withstand any corrosive effects of the sample. Identify the methods to ensure a safely maintained sample handling system. Identify the importance and function of the sample handling transport system. Identify the factors that determine lag time in a sample transport system. Explain the importance of sample conditioning. Describe and explain the different ways block-and-bleed and double block sample switching systems operate.
