Enviro analysis
Excellent and reliable autosampler. No trouble at all except one setback. The multiple injection (for example in solvent vent mode) does not have repeatable delays between the injections and even by setting the delay precisely in the software you do not receive repeatable response of injection times. According to our local distributor, Agilent is aware of this but new firmware that would fix this issue was not released yet.

The Agilent 7693A Automatic Liquid Sampler (ALS) provides dependable, fast, and precise injections for Agilent GC and GC/MS systems. The modular design allows this autosampler to grow with your lab. You can start with a 16-vial injector tower then expand to the 150-vial tray and add a second tower for dual simultaneous injections to increase throughput. For additional sample prep capabilities or sample tracking, upgrade to the heater/mixer/barcode reader module.
Features
- 150-sample vial tray allows longer unattended operation
- Dual simultaneous injection increases lab productivity by doubling sample throughput
- Fast injection technology minimizes needle discrimination and enables the use of external standards
- Sandwich injections of three layers eliminate manual error from internal standard, surrogate, or analyte protectant additions
- Sample heater and mixer dramatically improves high molecular weight chromatographic results
- Heat the entire tray or cool it to sub-ambient temperatures to meet your lab’s needs
- Modular design allows the flexibility to easily move the sampler from GC to GC or start with a single injector and add on to the system as needed
- Priority sample capability means there is no need to stop a sequence to add the next most important sample
- Barcode reader allows the system to perform specific actions on mismatch, ensuring chain of custody
