Features of 7683 AutoSampler
- The fastest injection speed in the industry--five times faster than other ALS products on the market--which eliminates needle discrimination
- All the advantages of the 7683A autoinjector with a two-fold increase in solvent capacity
- With the new solvent saving mode on all Agilent 7890A, 6890, and 6850 GC systems, you can reduce solvent usage and associated costs by 75%
- A choice of normal, on-column, or multiple injections
- Variable pre- and post-injection dwell times to match manual injections or allow large-volume injections
- Introduction of sample volumes from 0.1 µL to 50 µL or more (with multiple injections)
- Variable sampling depths for ambient headspace or micro liquid-liquid extraction
- Two wash solvents for pre- and post-injection needle rinsing, virtually eliminating sample carryover
- A 100-sample tray for Agilent 7890A, 6890N series, 6890A, and 5890 Series II GCs that mounts away from the GC oven to prevent sample degradation or condensation
- The capability to protect sensitive samples by cooling individual tray quadrants (Agilent 7890A and 6890 series GCs only) to sub-ambient temperatures
- None of the complexity and large solvent volumes of sandwich injection and other outdated injection techniques
- The capability to use external standards, simplifying quantitation
- A modular design, with options for increased automation
- Fast and easy transfer of sampler modules from one GC to another
- Easy inlet maintenance and fast, inexpensive repair if necessary
- Part of Agilent’s continuous product improvement and testing activities to ensure the best possible performance and reliability
- Purchase a state-of-the-art Agilent autosampler today for your Agilent 5890 Series II, 6890, and 7890A GCs knowing that you will be able to use that autosampler when you eventually replace your GC with a new Agilent system
General Specifications
| Power Requirements | 100-120 VAC or 220-240 VAC, 50/60 Hz, 180 VA |
Additional Specifications
Injector drive features: Electronic motor actuation with position feedback and control. No air actuators or periodic mechanical adjustments required.
[u]Sample Management[/u]
Sample capacity (2 mL vials): Eight samples with high-density turret; 100 samples with tray.
Tray samples stored in removable and stackable quadrants.
Sample sequencing: Random access using Agilent ChemStation control. Simple sequencing using the 7890A/6890 Series GC keyboard, Agilent integrator, or ALS controller software for 5890 Series II GCs.
Priority sampling mode: A priority sample and method can be inserted into the sequence at any time.
Sample thermal control: Sampler tray positioned away from GC to minimize exposure to heat. Tray quadrants can be cooled or heated using customer-supplied water circulator.
Temperature range: 5-60°C.
Bar code reader module: Reads 3 of 9, 2 of 5, and UPC bar codes. Sample information is automatically annotated on sample report from Agilent integrator or ChemStation. Not available for 5890 GCs.
Bar code label dimensions: 5.6 x 37.0 x 0.2 mm (maximum)
[u]Sample Injection[/u]
The 7683B injector provides a wide range of injection capabilities to provide maximum flexibility:
[i]Injection ranges[/i]
