OPTIC-4 Multi Mode Inlet

OPTIC-4 Accessoiries

Peltier Cooler for OPTIC

inlet peltier cooler Cooling down the OPTIC inlet till 30°C can be done with air, but for some cold injections in gas chromatography it is needed to inject below ambient temperature. To cool the OPTIC inlet below ambient temperature cryogenic solutions are needed. LN2 or LCO2 solutions are not always welcome in the lab and they require also refilling. With the OPTIC Cooler it is now possible to cool the OPTIC inlet till 7°C with just dry Air or Nitrogen.

Application: LVI Pyridine and N-Nitrosodimethylamine in Dichloromethane.

Inlet Backflush

backflush tee With automated liner exchange, it is necessary to open the injector head before the liner is transferred from, or to the injector. When the injector- head is open, air and water can flow into the system. This can be harmful to the GC-column and MS. Therefore a back flush of the injector is necessary. To avoid practical problems, we developed a new tool, the T-joint, an practical solution for the use of back flush in GC.

The only difference between normal installation and using the T-joint for back flush is that the column goes through the T-joint to the injector. The original flow path is exactly the same as normal without back-flush. After installation the back-flush is then introduced from the bottom of the injector.

OPTIC-4 Auxiliary EPC Channel
This channel can be used to upgrade your OPTIC-4. The auxiliary channel can be used for backflush. Easy to install yourself.
Part Number: 2406-4174 OPTIC-4 Auxiliary EPC Channel
Merlin MicroSeal Merlin Microseal
The Merlin Microseal is a long-life replacement for the standard septum used in Gas Chromatography. High pressure capability and resistance to wear make it the most unique septum on the market today. The Microseal fits standard in the OPTIC-4 inlet without modification.
Part Number:   410    High-Pressure Merlin Microseal
Part Number:   1100   Microseal for 1.1 mm SPME Arrow probes
Part Number:   1500   Microseal for 1.5 mm SPME Arrow probes

OPTIC-4 Top Boss Assembly for PAL SPME-Arrow
This top assembly is needed for PAL SPME-Arrow. The Arrow needle has a bigger O.D. and for this reason a different Top Boss Assembly is needed.
Part Number: 2406-4185 OPTIC-4 Top Boss Assembly, Arrow, Standard Type
Part Number: 2406-4186 OPTIC-4 Top Boss Assembly, Arrow, Shimadzu Type
Please take care, this Top Boss is for a standard inlet, not for LINEX.

Also available is a special Arrow liner.
OPTIC on-column tool kit
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 very easy to install without any press fit connection. The syringe needle (gauge 26) goes really into the retention gap where the injection takes place.

2406-4164 OPTIC on-column tool kit    It includes:
Deactivated F. S. Capillary Tube 10m 0.530I.D. x 0.660O.D.
10 ul Syringe, Cone Tip for PAL, gauge 26s
OPTIC Graphite Ferrule for 0.53 mm ID Column, pk/10
OPTIC Non-stick O-ring Viton, plasma treated, pk/10
Inlet Bottom Nut, pk/1
OPTIC On-Column Tool
SilTite Micro Union 0.1-0.25 mm ID to 0.53 mm ID Columns
