全能进样系统 (UNIS)
Extend the range of sample introduction in your GC!
The JAS UNIS, UNiversal Injection System, is an exchangeable all-in-one inlet system for Agilent GCs, which allows the user, to perform different injection techniques with one inlet system:
- (Pulsed) Split/Splitless Injection (S/SL)
- (High) temperature programmable evaporation (PTV, HT PTV)
- On-Column Injection (CoC)
- Headspace Injection
- Injection on (micro-) packed columns
- Large Volume Injection (LVI) / Solvent Vent
- Gas sample introduction (VOC/P+T, HSS, CTC-HSS)
- Manual Thermodesorption (TD)
Choose from our UNIS Family the best suitable inlet for your application. The standard S/SL-inlet UNIS 500, the versatile UNIS 2100 PTV inlet or one of the high temperature models UNIS 3100 HT PTV and UNIS HT SimDis – All GC injectors are designed in such a way that they perfectly fit in the 7890, 6890 and 6850 GC models from Agilent Technologies. The flow- and temperature control is done via the Agilent OpenLAB ChemStation Software, or via the keyboard on the GCs. For corrosive samples the UNIS is optional available in a deactivated version. All UNIS models include an Agilent EPC (Electronic Pressure Control), which garantuees the highest possible reproducebility. JAS offers you the standard EPC with max. operating pressure up to 100 psi and optional a high pressure version up to 150 psi.
JAS offers a wide range of application depending liners, which can be used in all UNIS models. The liner exchange and installation of columns is quick and simple - without any tools.

Adaptors
Headspace Sampler
Several kits are available to replace the UNIS standard septum nut with a dedicated connector for common used Headspace Samplers. The picture shows an Agilent 7694 Headspace Sampler connected to an UNIS 2100 PTV installed on an Agilent 6890 GC.
TDS Interface
With the UNIS TDS Interface we offer you an alternative for the traditional TD systems. The loaded adsorption tube is placed direct in an UNIS injector body and then desorbed. In combination with the JAS CryoTrap the system can be integrated in a GC without any problem and saves benchspace! The user-friendly leverage handle together with the leaktight UNIS injector head allows a quick exchange of the TDS sampling tube. The conversion of the injector can be done by the user within a short period of time. In this way switching between thermodesorption and liquid injection can be done with minimal downtime.
VOC Interface
The UNIS VOC Interface for volatile organic components consists of a septumless design. External sampling systems like TDS or pyrolysis can easily be connected, robust and gastight via an integrated 1/16" connector.
