Agilent 1200 HPLC System with Variable Wavelength Detector
The Agilent 1200 HPLC System guarantees the most efficient
mixing and pulse-free solvent delivery for consistently fast and accurate
results. The system’s optimized design using a quaternary pump allows variable
stroke volumes for stable solvent flow. This electronically activated inlet
valve runs synchronous to the pistons to eliminate vapor formation in volatile
solvent, making the Agilent 1200 both remarkably easy-to-use and
maintenance-free. It also features a high-speed proportioning valve and a
pre-configured degasser, which allow convenient low-pressure mixing and a large
solvent choice flexibility. The HPLC System’s vacuum degasser ensures reduced
operating costs without the use of helium and optimum instrument performance.
The Agilent 1200 VWD offers programmable wavelength switching for sensitivity and optimized selectivity optimized to each analyte’s elution, along with stop-flow wavelength scanning for quick wavelength optimization. The Agilent 1200’s
temperature management system ensures optimum baseline stability-even under
rough ambient conditions. This detector features superb illumination using
combined deuterium and tungsten lamps for the highest intensity and lowest
detection limit from 190 to 950 nm, 1024 diodes and 1-nm slit for highest
spectral resolution. The programmable slit helps you explore the spectral
landscape for faster sample characterization, ensuring higher sensitivity or
lower baseline noise as necessary on the 1200. Slit settings can be stored and
reported from 1 – 16 nm with raw data for GLP traceability.
The unit can be operated with a hand-held controller or
computer running Clarity software. The HPLC System features extensive
diagnostics with compatible data analysis software for on-site and remote
trouble-shooting.
This Agilent system is in excellent condition and will be fully tested to perform at factory
specifications before being shipped.

Below is a List of Diagnostic Tests Performed On This System
- Filter Test: The test moves the filter into the light path and measures the relative absorbance in the filter position.
- Dark Current Test: The test measures the dark current from the detector optic.
- Holmium Oxide Test: The test measures the Holmium spectrum from the built-in Holmium filter. The spectrum is evaluated for peaks at different wavelengths.
- Lamp Intensity Test: The test verifies functionality of the UV lamp at various wavelengths.
- Wavelength Intensity Test: The test confirms the accuracy of wavelengths measured.
- Baseline Noise Test: The test measures the amount of baseline noise drift identified by the detector.
- Pressure Test: The pressure test is a quick, built-in test designed to demonstrate the pressure tightness (up to 400 bar) of the system.
- Leak Test: The leak test is a built-in troubleshooting designed to demonstrate the leak-tightness of the pump.
- Thermostat Test: Evaluates the cooling and heating performance of the two Peltier elements.
- Injector Steps: Performs each movement of the sampling sequence under manual control. This is useful for confirming autosampler functionality.
- 4 Peak Test (Isocratic Standard): Standard test published by Agilent to confirm complete functionality of the 1200 HPLC System.
