- Low noise for high-sensitivity analysis
The Models L-2400 and L-2420 have realized the noise level of less than 0.6 x 10-5 AU, displaying the great power in detection of minor components.
- High response and low noise for high-speed analysis
The noise level is low even when the response is set at 0.05 second, maintaining accurate identification of sharp peaks, as well as high-speed, high-sensitivity analysis.
- Excellent stability free from influence of changes in ambient temperature
The site environment can vary for each laboratory.
The LaChrom Elite detectors are designedto protect the optical system from heat to flexibly adjust to dayand- night temperature fluctuations and seasonal temperature changes, thereby ensuring excellent results with stable repeatability at all times.
- Inspection of wavelength in ultraviolet range using a built-in Hg lamp
The 254 nm line spectrum of the Hg lamp built in the detector permits inspection of wavelength in the ultraviolet range which is frequently used for LC. In combination with the line spectrum of the D2 lamp, three wavelengths in total are used for inspection to ensure high-reliability analysis in a wide range of wavelengths.
- Front accessibility for improved maintainability
The lamp and flow cell can be replaced from the front, providing easy maintenance.
