7683 AutoSampler

The Agilent 7683 autosampler raises the standard for gas chromatography (GC) system performance and reliability. This next-generation Agilent automatic liquid sampler for the Agilent 7890A, 6890N, 6890 Plus, 6850 Series and now the 6890A and 5890 Series II gas chromatography systems offers all the features of our popular Agilent 7673 automatic liquid sampler and more--in a compact, rugged package. This is the automatic sampler to have for: accuracy and ease of use; superior reproducibility, with minimal rework; easy accommodation to changing needs; optimum injection flexibility; and enduring reliability.
7683 AutoSampler
Attributes
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.    
    
Sample Management    
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)    
    
Sample Injection    
The 7683B injector provides a wide range of injection capabilities to provide maximum flexibility:    
Injection ranges    
Syringe sizes: 0.5, 1, 5, 10, 25, 50, and 100 µL    
Injection volume selection: 2%, 10%, 20%, 30%, 40%, or 50% of syringe volume    
Usable syringe rinse solvents*: Solvent A: 6 mL, Solvent B: 6 mL    
*With solvent saving mode for use with Agilent 7890A, 6890 Series, and 6850 Series GCs, the number of available solvent washes is increased by up to a factor of four.    
    
Technical and Environmental    
Indoor use only in ordinary atmospheres.    
Altitude: Up to 4,300 m    
Operating ambient temperature: -45°C to -5°C    
Maximum relative humidity: 80% for temperatures up to 31°C decreasing linearly to 50% relative humidity at 40°C    
Mains supply voltage fluctuations: Up to +/- 10% of the nominal voltage    
Pollution degree: 2    
Installation: Cat II

Features

        
  • 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

Auto sampler stalls

I have a 7683 autosampler on GC-MS and GC-FID instruments. They are about 15 years old. Recently, both autosamplers stopped working. Once an analysis is initiated, the carosel does its thing spinning around, the syringe mechanism lowers to the waste...

Noise & vibration

Hello: My 7683 ALS tower is making a humming sound and the tower vibrates. I removed the back and it appears to be the fan at the top of the tower. Should the fan be changed or is there something else I could try. Thank-you.

not lifting the vial

7683 arm  touches and tries to lift vial but failed to do so hence please guide.
