Inlet Liner

SAMPLE INTRODUCTION – GC Inlet Liners

 

The GC inlet functions as the interface between the syringe and the GC capillary column, where the sample is introduced, vaporized, mixed with carrier gas and transferred to the column. Shimadzu instruments offer several types of inlets - split, splitless, programmable temperature vaporization (PTV) and on-column.

 

The inlet liner prevents the sample contacting the metal walls of the injector block. Inlet liner geometry and packing materials enable the inlet liner to achieve greater heated surface area; this additional surface area can often improve sample vaporization. Conversely, choosing the wrong inlet liner geometry can significantly decrease the reproducibility and quality of analysis.

Active Compounds
Taper
A bottom taper focuses sample onto the head of the column and minimizes sample contact with metal parts of the inlet. The addition of quartz wool to your inlet liner promotes mixing of analytes, aids the vaporization of liquid samples, and works as a trap to collect non-volatile residue in the sample (i.e. protects capillary column from "dirty" samples).
Split
General Purpose/
Concentrated Samples/
Dirty Samples
FocusLinerTM
Ensures quartz wool remains in the correct position in the liner. Excellent reproducibility results from the wiping of the sample from the syringe needle and the prevention of droplet formation. Minimizes high molecular weight discrimination.

Wide Boiling Point Range
Taper FocusLinerTM
Bottom taper focuses sample onto the head of the column and minimizes contact with metal parts of the inlet. Excellent reproducibility results from the wiping of the sample from the syringe needle and the prevention of droplet formation. Minimizes high molecular weight discrimination.
Direct
Trace Level Analyses/
Active Compounds
Direct Taper
Direct inlet liners facilitate maximum transfer of sample by connecting directly to the GC column and inhibiting sample degradation due to hot metal components inside inlet.

General Purpose/
Concentrated Samples/
Dirty Samples (only if quartz wool is present)/
Gaseous Samples (also purge & trap, headspace)
Straight
Straight inlet liners facilitate higher split flows. Narrow bore straight inlet liners facilitate fast GC work. Small injection volumes of less than 0.5 μL are best used with a narrow bore. Narrow bore straight inlet liners improve focussing of gaseous samples (purge, trap & headspace).

 

Inlet Liner Deactivation
 

Every batch of inlet liners are tested for inertness using the EPA 8081B method. This standard method ensures that each batch of inlet liners has less than 3 % Endrin breakdown from a 1 ppm injection.

 

 

Glass Insert for Capillary Column Analysis

 

Glass insert is very important to prevent the column from being contaminated by sample components. Please choose an appropriate insert according to your system model, injection port and injection method, and exchange it regularly to avoid poor reproducibility and peak shape caused by the crossover of residual samples, etc.

Glass Insert for Packed Column Analysis

 

When using a glass column, one may add a glass insert to prevent the column from accumulating non-volatile components. Please choose a proper insert according to the inter diameter of the glass column.
When using a stainless column, it is necessary to connect a glass insert to a 3.0 mmID column at the side of the injection unit. Please exchange it regularly to avoid poor reproducibility and peak shape caused by the crossover of residual sample, etc.
Note: Glass insert cannot be used in a GC-8A Series instrument when using glass columns.
