An open-ended column refers to a column that is open at both ends, allowing substances to freely flow in and out. This type of column is commonly used in chromatography, where it provides a larger surface area for interactions between the stationary phase and the sample being analyzed.
On the other hand, a closed column refers to a column that is sealed or closed at one end. This type of column is typically used in gas chromatography, where the sample is introduced at the closed end and the mobile phase (inert gas) flows through the column to separate the components. The closed end helps to ensure the proper flow of the mobile phase.
