Carrier Gas Saving

The supply for helium carrier gas for GC-MS became increasingly difficult and expensive in many regions. Saving helium carrier gas is especially important with 

Anti-diffusion tubing prevents N2from entering the column with a counter flow of helium carrier gas

Use 0.53-mm-I.D. (megabore) columns as replacements for packed columns or for high sample loading applications. Use of these columns also permits lower split ratios, resulting in carrier gas savings.
