7650A Automatic Liquid Sampler
The Agilent 7650A Automatic Liquid Sampler (ALS) provides reliable, fast, and precise injections for Agilent GC and GC/MS systems.
The Agilent 7650A Automatic Liquid Sampler (ALS) provides consistent, reliable injections of up to 50 samples on Agilent GC and GC/MS systems for more reproducible and accurate results. Prepare to inject the next sample in the sequence before the GC goes ready with sample overlap. Add critical samples to the queue at any time without interrupting the sequence.
Features
- Holds up to 50 samples
- Up to three layers in sandwich injection mode
- Quick and easy self-alignment for inlet and sample position
- Illuminated syringe carriage for easy viewing, troubleshooting, and method development
- Fast injection technology minimizes needle discrimination and enables the use of external standards
- Perform single-stroke and multi-stroke injections
- Holds up to 250-µL and 500-µL syringes for large-volume injections
- Priority sample capability means there is no need to stop a sequence to add the next most important sample
The analysis of monocyclic aromatic hydrocarbons by ASTM D7504 on the Agilent 8850 GC system
Accurately quantifying aromatic contaminants in fuels can be time-consuming and technically demanding, especially when balancing speed with precision. Meeting ASTM D7504 requirements adds further complexity to method development.
Discover how a streamlined gas chromatography approach, combined with method translation software, enables both conventional and fast separations with excellent reproducibility and sub-1.0% RSD performance.
