Agilent 7693A ALS automatic liquid sampler

• 150 sample trays can achieve longer unmanned operation time
• Simultaneous injection of dual towers can double the sample analysis capability and save a lot of time
• Rapid injection technology can minimize needle discrimination and facilitate the use of external standards
• Eliminate artificial errors introduced during sample pretreatment, including dilution, addition of internal standards, and derivatization
• Can accommodate 250 µ L and 500 µ L injection needles for sample pretreatment
• Easy SamplePrep software can be used to easily create and run gas chromatography sample pre-processing programs
• Sample heaters and mixers can significantly improve the chromatographic results of high molecular weight compounds
• Can heat the entire sample tray or cool it below room temperature to meet laboratory requirements
• Modular design allows for flexible movement of the injector between gas chromatographs, or the use of a single injector for upgrading as needed
• Priority sample function. When adding the next important sample, there is no need to stop the current sequence
• The barcode reader enables the system to take specific measures in case of mismatches, ensuring the chain of custody for Agilent barcode printing solutions.
• Upgrading the old automatic sampler to 7693A can extend the service life of 6890N GC

Sample pre-treatment

Dilution, addition of standard samples, and derivatization; Save time and eliminate manual errors

Overlap with the next sample
Prepare the next sample in the injection sequence before gas chromatography is ready; Shorten the time between two injections

Modular design
Improve the performance of the automatic sampler to meet the constantly expanding needs of the laboratory

Simultaneous injection of two needles
Achieving twice the sample flux in a gas chromatography system
