Detailed understanding of mechanisms and reaction kinetics are required in order to develop and optimize catalysts and catalytic processes. While steady state investigations are known to give a global view of the catalytic system, transient studies are invaluable since they can provide more detailed insight into elementary steps. For almost thirty years temporal analysis of products (TAP) has been successfully utilized for transient studies of gas phase heterogeneous catalysis, and there have been a number of advances in instrumentation and numerical modeling methods in that time. In the current work, the range of available TAP apparatus will be discussed while detailed explanations of the types of TAP experiment, the information that can be determined from these experiments and the analysis methods are also included. TAP is a complex methodology and is often viewed as a niche specialty. Here, part of the intention of this work is to highlight the significant contributions TAP can make to catalytic research, while also discussing the issues which will make TAP more relevant and approachable to a wider segment of the catalytic research community. With this in mind, an outlook is also disclosed for the technique in terms of what is needed to revitalize the field and make it more applicable to the recent advances in catalyst characterization (e.g. operando modes).
