GC Inlet Liners – Which one should I choose? part 2

For Splitless Injection use Liners with Taper at the bottom

  • The taper minimizes contact of analytes with the bottom of the injection port. This is especially important in splitless injection mode because the residence time of the sample in the liner is longer.
  • Column installation into the liner becomes more robust because the taper ‘channels’ the analytes into the column. The distance the column is inserted into the liner is not so critical.

 

For Splitless Injection – Very Active Compounds

  • The taper minimizes contact of analytes with the bottom of the injection port. This is especially important in splitless injection mode because the residence time of the sample in the liner is longer.
  • No quartz wool.

 

For Fast GC Column Analysis use Liners with Narrow internal diameter

  • Results in smaller peak widths.
  • Especially suited for (100μm) Fast columns.
