零长柱技术是近30年来发展起来的一种测量吸附平衡和动力学的通用实验方法。在这篇评论中，我们详细讨论了理论，形成的技术基础，以了解如何设计和有效地运行一个系统。应进行实验检查，以确保正确的动态响应的解释，并使用实例来确定如何避免在确定扩散时间常数的重大错误。审查的结论与文献中提供的所有实验研究的概述和一组建议，应有助于提高标准的平衡和动力学性能的报告。
The zero length column technique has been developed over the past 30 years as a versatile experimental method to measure adsorption equilibrium and kinetics. In this review we discuss in detail the theory that forms the basis for the technique in order to understand how to design and operate efficiently a system. Experimental checks that should be performed to ensure the correct interpretation of the dynamic response are presented and examples are used to identify how to avoid major errors in determining diffusion time constants. The review concludes with an overview of all experimental studies available in the literature to date and a set of recommendations that should help improve the standard in the reported equilibrium and kinetic properties.
