Agilent 6890N System Capabilities:
- Dual channel design supports two inlets and two detectors.
- Full range digital data output enables the smallest and largest peaks to be quantitated in a single run.
- Full EPC is available for all inlets and detectors. Control range and resolution are optimized for the specific inlet or detector module.
- EPC with capillary columns provides four column flow control modes: constant pressure, ramped pressure (3 ramps), constant flow, or ramped flow (3 ramps). Column average linear velocity is calculated
- Atmospheric pressure and temperature compensation is standard, so results do not change, even when the laboratory environment does.
- Automatic Liquid Sampling is fully integrated into mainframe control.
- Set point and automation control can be done from the local keyboard or via a networked data system. Clock-time programming can be initiated from the front panel to initiate events (on/off, method start, etc) at a future date and time
- A run time deviation log is created for each analysis to ensure that all method parameters were achieved and maintained.
- Display of all GC and automatic liquid sampler (ALS) set points at the GC or data system. Agilent supports open connectivity by providing communication protocols to other vendors software such as ChromPerfect & Clarity
Configuration Options :
- Wide selection of inlets
- Split/splitless (S/SL) capillary
- Packed purged injection port (PPIP)
- Cool on-column (COC)
- Cool on-column with solvent
vapor exit (COC-SVE)
- Programmable temperature
- Volatiles interface (VI)
• Cooled injection system (CIS)
Endlessly Configurable with;
- Agilent 7683 automatic liquid sampler
- Agilent G1888 headspace sampler
- Agilent 7694E headspace sampler
- Purge and trap
- Gas and liquid sampling valves
- Ambient air sampler and pre-concentrator
- Thermal desorber
No Sample Preparation? Headspace sampling can eliminate sample preparation by introducing volatile components automatically—from virtually any matrix—directly into the GC. A low-volume, highly inert volatiles interface is optimized for headspace-GC analysis, preventing sample loss or degradation. Agilent headspace instrument control is fully integrated into the software. High Sample Throughput The 6890N network GC system is already set up for the Agilent 7683 automatic liquid sampler, enabling fast and easy installation. Single or dual injectors, equipped with either an 8-sample turret or a 100-vial sample tray, allow unattended operation. Using the 11-vial transfer turret with the tray and the solvent saving mode, you have enough solvent to run unattended eight times longer than before.
