Complete confidence from spectral data
The Agilent 1200 Series diode-array detector adds spectral acquisition to your HPLC analyses. Verify separation quality with peak purity, multiple signals and spectral libraries - interactively or automatically in the same run as your analytical quantification. Extended wavelength range from 190 to 950 nm with highest sensitivity or spectral resolution with programmable slit. And holmium oxide wavelength verification for GLP compliance. The temperature management system ensures optimum baseline stability–even under rough ambient conditions.
Features
- Access the spectral domain with superior 3D optics–simultaenous illumination using combined deuterium and tungsten lamps for highest intensity and lowest detection limit from 190 to 950 nm, 1024 diodes and 1-nm slit for highest spectral resolution.
- Programmable slit to explore the spectral landscape for faster sample characterization–focus on fine bands with narrow setting, or if higher sensitivity is required open up the programmable slit for more light throughput. A broad slit ensures lowest baseline noise and highest chromatographic signal-to-noise. Store and report slit settings, from 1 - 16 nm, together with your raw data for GLP traceability.
- Convenient spectral storage and flexible viewing –easily overlaid spectra within a run or between runs.
- Verify wavelength accuracy for GLP compliance–automatic holmium oxide filter verifies that your wavelength is indeed what the setpoint says it is.
- Connect to LC/MS–high pressure micro flow cell for extremely small internal volumes are required for LC-MS applications and use a single Agilent ChemStation to acquire and view UV and MS spectral data.
- Explore capillary HPLC– flow rates as low as 5-µl/min with the new 500-nanoliter flow cell. Increase sensitivity 50 to 100-fold compared to standard-bore HPLC.
- Easy front access to lamp and flow cell for fast replacement
- Low cost of ownership - long life deuterium lamp (>2000 h), built-in diagnostics software
