Agilent 7693A Series Automatic Liquid Sampler
A powerful combination of productivity and flexibility
It is no surprise that GC and GC/MS precision begins with the autosampler. What can be a surprise is what an autosampler can do for your analyses. With over 50 years of GC leadership, Agilent builds on basic injections to provide innovative autosampler capabilities, delivering useful method performance enhancements.
Agilent’s 7693A Automatic Liquid Sampler (ALS) takes advantage of today’s latest technology to deliver even greater reliability, performance, and flexibility. It provides sample preparation capabilities and a wide range of injection techniques for a wide range of sample types.
Whether you have hundreds of samples to analyze, or just a few, the 7693A system gives you sample handling and injection capabilities that are best in class.
Enhanced performance and productivity
From small-volume injection, to large-volume injection, to multi-layer sampling, the 7693A system can help you process samples more quickly—and get better data, too.
Agilent’s dual simultaneous injection feature saves time by doubling your sample throughput. And our fast-injection technology minimizes needle discrimination and sample degradation. It also ensures the best possible peak shape, while maximizing the accuracy of your results.
No built-in autosampler can match the flexibility you get with the 7693A ALS. The system’s modular design work seamlessly with 6890N, 7820, 7890, and Intuvo 9000 GC systems.
What’s more, the 7693A system adapts easily to your lab’s changing needs. For example, you could start with a basic injector equipped with a 16-sample turret; later, you could add a second injector, a 150-sample tray, and a vial Heater/Mixer/Bar Code Reader.
The self-aligning “plug and play” injector mounts in seconds without tools, and can easily be moved from one inlet to another—or transferred between GCs when workloads change. Its lightweight, removable design also permits easy inlet maintenance.
In addition, greater solvent capacity ( >20 mL), plus the ability to load up to 150 samples, means longer unattended operation. Solvent-saver mode will increase your capacity even more. And built-in Agilent reliability gives you the confidence to run the system day and night with minimal operator attention—and without the need for calibration or adjustment.
*6890A/7820A requires optional controller.
Sample capacity to meet any requirement
With its expanded 16-vial turret, the 7693A’s standard configuration provides up to 8 hours of analysis. Need more capacity? The 150-vial tray is up to the task.
Active fingers hold each vial by its sides for greater flexibility in handling a wider range of vials and caps. Sensors also detect whether or not a vial has been grasped
A choice of injection modes
Agilent’s fast injection enhances chromatographic results by ensuring minimal needle discrimination and sample decomposition. Plunger speed can be precisely regulated, enabling true optimization for large volume injections or challenging applications.
Heater/Mixer/Bar Code Reader
An optional Heater/Mixer/Bar Code Reader and second injector can be used to prepare highly viscous or slightly soluble samples, as well as for dilution, mixing, derivatization and bar-coded sample tracking. All functions are controlled via easy-to-use software.
Next sample overlap support
Decrease your analysis time and increase throughput by performing pre-run rinses and picking up the next sample before the current run is complete.
Modular design for easy service and support Should service be required, repair options include returning the system to Agilent for quick exchange or repair. Onsite repair is also available, depending on your lab’s needs.
Three modular sections suit your current—and evolving—needs
Automates the analyses of up to
sixteen samples with a capacity for two solvent bottles and one waste bottle. When combined with the vial tray, the injection tower can hold ten solvent
vials and five waste vials, as well as three sample vial transfer positions— giving the system unprecedented sample handling flexibility.
This unique vial handling system uses three separate 50-vial racks for a total capacity of 150 samples. A full tray heater/cooler is also available, along with a separately supplied recirculating temperature bath.
Heater/Mixer/ Bar Code Reader
To give you even more sample handling capabilities, an optional module allows heating, mixing and bar code reading of samples immediately prior to injection.
In addition, our new Bar Code Label Printing Bundle lets you print easy- to-read bar code labels right from a spreadsheet or database—minimizing typos and ensuring accurate Sample
ID and tracking. The bundle comes complete with printer, software, templates, and labels.
PRE-INJECTION SAMPLE HANDLING SAVES STEPS, BOOSTS PRODUCTIVITY
In addition to conventional and fast injection modes, the 7693A system offers pre-injection sample handling capabilities that can further enhance your lab’s flexibility, productivity, and performance. Ideal for routine sample handling in a wide range of industries and applications—including forensics, food and environmental analysis—this can eliminate or minimize separate sample prep work, saving both time and resources.
The addition of a second injection tower, optional Heater/Mixer/ Bar Code Reader and easy-to-use Agilent software gives you the flexibility to optimize for performance, cost-efficiency, or unique analytical requirements. For example, you can add a derivatization agent—or heat the sample vial, add a second solvent, mix it and inject into the system—all automatically!
