Earth particles are used because the packing$GC$in columns.

Step-by-step solution

Step 1  The Components.

The Components. The gas chromatographyis particularly accustomed separatea combination of volatile components. The components are isolatedemploying a gas phase mobile phase and a liquid or solid stationary innovate the column.

 Components material.

The wadding in is particularly composed of solid support that's usually diatomite particles (typically have diameters starting from to or to ) $250$to $170\mu m$ or $170$to $149\mu \mathrm{m}$) coated with a stationary phase like $OV-x$or carbowax.
