UV- 4070/4075UV-Visible Detectors

Using the advanced Czerny- Turnermonochromator design with optimization of the optical system, baseline change due to refractive index is minimized. Baseline fluctuation from changes in environmental temperature is reduced with a temperature - controlled cell, baseline drift caused by temperature fluctuation in the light source is also reduced with a temperature controlled light source. The result is excellent stability with UV-4070 UV Visible UV spectra auto-scan Automatic spectral scannning can be controlled using ChromNAV, when a peak exceeds a set threshold a scan is executed automatically. 0.24 220000 200000 the noise level +/- 0.2x10 -5 AU and drift 1x10 -4 AU/h.

Both detectors offer simultaneous dual-wavelength data acquisition and spectral scanning. User maintenance can be done without removing the module from the system. Front-panel access is used for light source replacement and automatic wavelength calibration can be carried out using a mercury lamp. Both detectors include high speed data acquisition at up to 100Hz and can be used for conventional HPLC with the standard flow cell and for UHPLC/RHPLC when used with the SP type semi-micro cell.
