Can I do On-Column with OPTIC?

Category: OPTIC

The OPTIC inlet can also be used for on-column injections. GL Sciences has designed a tool that enables true on-column injection using OPTIC inlet without an on-column liner. The on-column tool is ver...

How should I condition a TD tube?

Category: LINEX

Before TD tubes can be used the desorption tubes must be conditioned. Conditioning involves the continuous flow of a high purity carrier gas (either Nitrogen or Helium) while the desorption tubes are ...

How can I optimize my Large Volume Injection (LVI) ?

Category: OPTIC

We recommend you to read the training guide first. Optimization Routine For Large Volume Injection This LVI routine is based on OPTIC and fast (not speed controlled) injections. A packed liner (sinter...

Siloxane peaks in baseline GCMS

Category: OPTIC

GC-MS Siloxane Peak Contamination (masses 73, 147, 207, 281, 355) Running a baseline chromatogram done without sample or solvent injection should show a nice chromatogram without peaks, but sometimes ...

How often do I need to replace the Split Line Filter?

Category: OPTIC

The OPTIC-3 and OPTIC-4 Multi Mode Inlet for Gas Chromatography have a filter in the Split liner to protect the Electronic Gas Control. This filter needs to be replaced minimum once per year, but if y...

What Ramp Rate should I use for Thermal Desorption (TD)?

Category: OPTIC

The OPTIC inlet is used a lot for TD applications. The most common TD application is a desorption of a Tenax filled tube/liner. After placing the TD tube, the tube should be flushed with the carrier g...
