General description
Molecular sieves are synthetically produced zeolites (naturally occurring aluminosilicate minerals), and are characterized by pores and internal cavities of extremely uniform dimensions. These crystalline materials have three-dimensional structures based on silicon oxide (SiO4) and aluminum oxide (AlO4) polyhedra. The polyhedra are linked by their corners to produce an open structure with internal cavities in which molecules can be trapped. These materials are engineered so that access to the internal cavities is through specific and uniform sized pores.

What does the 60/80 stand for in the product description?
1 answer-
The 60/80 refers to the mesh size range of the actual particles. When working with mesh size: the larger the mesh number, the smaller the diameter of the particle. In this case 60 refers to a diameter of 250 microns and 80 refers to a diameter of 177 microns. Therefore; the particles in this product with 60/80 will range between 177 microns and 250 microns.

How do you condition Molecular Sieve 5A, Product 20302, when used in a packed column?
1 answer-
Attach the column to your GC injection port, establish a flow rate of at least 25 mL/min carrier gas, purge with carrier gas at room temperature for 30 minutes, increase oven temperature to 225°C at a rate of 4°C/min, and allow the column to condition at 225°C for 8-12 hours. After conditioning, allow the oven to cool to room temperature, turn off the carrier flow and allow the pressure to go to zero. Then reinstall the column into both the injector port and detector port, and establish desired carrier flow rate. The column should then be ready to use.
