What you are buying
A refurbished Agilent 1200 Series G1362A refractive index detector. It measures refractive index for compounds without a chromophore, such as sugars and polymers.
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
Agilent built the G1362A to cover a refractive index range of 1.00 to 1.75 RIU, with a measurement range of plus or minus 600 times ten to the negative sixth RIU. The flow cell holds 8 microliters and takes up to 5 bar at flow rates to 5 milliliters per minute. Optical temperature control runs from 5°C above ambient to 55°C, which stabilizes the baseline against room-temperature drift. Automatic purge and solvent recycle valves cut solvent waste and simplify changeover between mobile phases. Internal volume runs 62 microliters from the inlet port to the sample cell and 590 microliters from the inlet port to the outlet port. Stainless steel, Teflon, and quartz glass make up the parts in contact with solvent, compatible with a recommended pH range of 2.3 to 9.5.
 
What each module does
Refractive index detection
Delivers the mobile phase at constant flow and blends the gradient. Isocratic, binary, and quaternary configurations cover everything from single-solvent assays to four-solvent method scouting. Stable flow is the basis for the retention-time reproducibility every quantitative method depends on.
Sampler
Measures refractive index for compounds without a chromophore, such as sugars and polymers, through a temperature-controlled flow cell. It drops into a compatible 1200 HPLC stack under OpenLab CDS or ChemStation.

What “GenTech Certified” means
Refurbishment at GenTech is a defined process, not a wipe-down. Every system moves through the same five 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. Data package you approve before shipment. The verification data goes to you for approval before the system leaves the bench. You see exactly how the instrument performs before it ships.
5. 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.
