Catalog excerpts
Full range diode array detector The Smartline PDA Detector 2850 is based on advanced fiber optics technology. It combines excellent technical specifications with outstanding operability. Optical excellence – No other instrument of this kind provides such a wide waveength range l matched with high light source intensity up to the NIR range. The detector has a very high resolution of 0.8 nm per pixel and operates with an impressive wavelength accuracy of ≤ 0.5 nm and a wavelength reprodu ibility (precision) of ≤ 0.1 nm. The Smartline PDA Detector 2850 c delivers best results in terms of sensitivity, noise and drift. Simply reliable – Due to its unique design the Smartline PDA Detector 2850 has no delicate moving parts to break down, operates without a reference channel or special »see through« lamps, and does not require a time consuming cold-start calibration. The instrument is completely controlled by the HPLC software. Its Ethernet interface provides for easy and secure connection to a TCP/IP network or directly to a PC, enabling reliable communication. Advanced functions – The Smartline PDA Detector 2850 can simultaneously acquire chromatogram data at up to four wavelengths and perform spectra scans at a maximum rate of 10 per second (the scan range can be selected from 190 –1 020 nm). In conjunction with the chromatography software this diode array detector offers features like 2-D and 3-D chromatograms, spectra libraries, peak purity tests, and more. This detector pro ides two adjustable v software-controlled analog outputs for the support of preparative applications. Application flexibility – The variety of available flow cells and the option to easily extend the fiber optics for positioning the cell outside the housing, make this detector well-suited for a wide range of applications.
