Enhanced detectability
By simultaneously monitoring two wavelengths (Model 525), you get maximum detectability of different compound types. You can also simultaneously ratio the wavelengths to check purity.
Reduce setup time
Easy to program and operate, the front-panel display guides you through the setup of even the most complex time-based program.
High sensitivity for demanding applications
Dual wavelength operation (Model 525) with programmable sensitivity from 0.0005 to 7.9995 AUFS gives you optimal detection capability.
Programmable peak detection and baseline correction
Lets you get the data you require. Enhance the accuracy of your detection results by matching the wavelength to the compound and sensitivity to the concentration range.
More than just a detector — it's also a spectrophotometer
When separating unknown compounds, program to monitor a wavelength range to identify and zero in on important peaks and scan the compound for its spectral characteristics.
Easy access and maintenance
Separate lamp and flow cell housings assure quick maintenance and changing of parts.
Complete line of flow cells
Standard Type 316 stainless steel; optional chemically inert, metal-free Kel-F®; and optional micro flow cells are available for optimal detection. Cells are also available for CZE and high-pressure applications.
Model 525 Dual-wavelength UV/Vis Detector
The Model 525 provides all the performance and features needed for either method development or routine analysis. Programmable, single- and dual-wavelength capabilities are standard. Six user files, a queue for file linking, and automatic lamp startup and shutdown enhance operation. Spectra can be collected “on the fly” without stopping the flow. The λMax, λMax AU, and λMin are displayed automatically in real time. You can replay any spectra or display the complete spectral data on the LCD. Ratio output is available for peak purity. The “Develop File” automatically analyses your separation at many wavelengths. Finding the best wavelength for sensitivity, selectivity, and quantization is quick and easy.
Model 201 Programmable UV/Vis Detector
The Model 201 is an easy-to-use, programmable wavelength detector designed for routine applications. Wavelength programming enhances the sensitivity or selectivity for different compounds in a separation The automatic lamp startup and shutdown feature prolongs lamp life and reduces warmup time. Programming is accomplished using a simple keypad and display. The "Status Lock" feature prevents accidental changes in parameters while the detector is running.
Wide variety of flow cell options
A wide variety of cell options is available for all applications. Analytical, micro, semi-prep, prep, and inert/bio flow cells are offered for LC. The high pressure (7000 psi) flow cell is ideal for SFC and LC-MS. An on-column cell for CE and SFC uses a ball lens to focus the light beam for increased sensitivity. A cuvette holder converts the detector into a spectrophotometer and makes fixed wavelength and scanning absorbance measurements accurate and reliable. All flow cells are pre-aligned for fast, simple installation and exchange.
