What you are buying
Optimized for high-performance liquid chromatography (HPLC) workflows, the Agilent 1200 Series G1329A is a dependable automated liquid sampler built to streamline routine lab analyses. A standard variable-volume autosampler, the Agilent G1329A features a single-needle design and a standard 100 µL metering device/sample loop configuration. This module automates sample introductions to maximize throughput while delivering highly reproducible and precise injections for every run.
Every unit moves through the GenTech Certified process. Solution Scientists disassemble and inspect each module, replace all consumables and degraded wear components, then tune and calibrate the instrument and verify performance against OEM and published benchmarks using known reference chemicals. The instrument ships with its verification report. A certified-refurbished system gives you that performance without the capital cost or the lead time of a new purchase.
What Agilent says about this platform
Both the Agilent 1100 Series autosamplers and Agilent 1200 Series autosamplers are designed for use with other modules of the Agilent 1200 Series LC system, with the HP 1050 Series, or with other LC systems if adequate remote control inputs and outputs are available. The 1200 series keeps full compatibility with existing HPLC methods and columns. Agilent designed the 1200 with more than 60 available instrument modules, covering prep-scale, standard, narrow-bore, capillary, and nanoflow LC on one platform.
What this autosampler module does
The Agilent 1200 (G1329A) Automatic Liquid Sampler (ALS) draws a precise volume from the vial and injects it onto the column. Automated sampling runs unattended sequences overnight.

What “GenTech Certified” means
Refurbishment at GenTech is a defined process, not a wipe-down. Every system moves through the same specific stages.
1. Disassembly and rebuild. Solution Scientists strip the instrument down, clean each module inside and out, and rebuild it from the frame up. They replace pump seals, pistons, and check valves to specification.
2. Configuration and new parts. Solution Scientists install the options and modules you selected and fit new wear parts throughout. They replace the detector lamp with a new one and reset the lamp hours.
3. Diagnostic and performance testing. Solution Scientists tune and calibrate the instrument, run system diagnostics, and confirm detector wavelength accuracy. They test full-system pressure and gradient performance against OEM and published benchmarks using known reference chemicals.
4. Delivery and installation. The instrument ships in protective packing with a one-year warranty option and professional installation available from a GenTech Solution Scientist.
Labs that run this system
The 1200 HPLC is method-compatible across the techniques most regulated and research labs run every day. These are the application areas buyers ask about most.
Assay, Impurity and dissolution
The 1200 transfers cleanly into USP monograph assays, related-substance profiling, and dissolution testing. Quaternary blending simplifies mobile-phase transfer between labs.
EPA HPLC methods
Diode array detection supports EPA HPLC methods for contaminants and residues in water and soil, including PAHs, explosives, and carbamates.
Additives and vitamins
The system quantifies preservatives, sweeteners, organic acids, and fat-soluble vitamins at the throughput a production-support lab needs.
Cannabinoid potency
HPLC with UV detection is the reference technique for potency. The 1200 resolves the major cannabinoids for compliance and label-claim testing.
Botanical actives
Labs quantify polyphenols, flavonoids, and marker compounds in extracts and nutraceutical formulations across long, reproducible sequences.
Screening and drug monitoring
The 1200 runs HPLC-UV workflows for therapeutic drug monitoring and drugs-of-abuse screening, where method portability and uptime matter more than peak novelty.
Purity and additives
Industrial labs separate and quantify synthesis intermediates, polymer additives, and stabilizers for QC and release testing.
Four-solvent scouting
Agilent recommends the quaternary pump for method development. Blend up to four solvents to scout selectivity before you lock a final method.
Proteomics, metabolomics, lipidomics
Many omics workflows use mass spectrometry for detection and rely on LC for separation. The 1200 serves as the front end feeding your MS or fraction collector.
