Popis

General description

In packed columns, the carrier gas percolates through the porous bed. In a packed column, separation is achieved by moving the solutes apart. Packed columns are made up of two main materials; stainless steel and Pyrex glass. Metal packed columns are more suitable for long and high carrier gas flow rates to tolerate the elevated pressures. Molecular sieves are three-dimensional framework structure that forms pores of molecular dimensions. The pores adsorb molecules which fit closely inside the pores and exclude molecules that are large. Zeolites are subset of molecular sieves. Molecular sieves are used as adsorbents, gas separations, oil refining and many diverse areas. X-ray diffraction, transmission electron microscopy and pore size analysis confirmed that molecular sieves consisted of a three-dimensional regular array of uniform mesopores which was 3nm in diameter.

An economical metal column should be used for less demanding applications where the inertness of glass is not required. This column is of a general configuration, and can be carefully bent to fit most instruments.

Application

• Adsorption properties and gas chromatographic application of a composite surface-layer sorbent with Terephthalic acid-based metal-organic framework: Demonstrates the use of metal-packed GC columns for enhancing the performance and durability of chromatographic analyses, particularly in environmental and material science testing (Onuchak et al., 2022).
