Detector

WESTINGAREA supplied L542113 detector have the excellent performance displayed as:

* Light Source(s): Mercury lamp for 254 nm and other wavelengths, tungsten
lamp for visible wavelengths (340 nm to 1000 nm), D2 lamp for any UV-VIS
wavelengths (190-1000 nm)

* Optical design: Interference filter with fiber optic beam splitter and
high sensitivity/low RI effect flowcell.

* Wavelength selection: User changed filters/elemental lamps, Hg lamp:
254 nm (standard), 280 nm (phosphor, option), 350 nm (phosphor, option),
370 nm (phosphor, option), Zn lamp: 214 nm, 308 nm, Cd lamp: 229 nm, 326 nm,
W lamp: 370 nm to 1000nm, D2 lamp 190 nm to 1000 nm

* Wavelength accuracy : Defined by the elemental line emission characteristic
of the lamp. In the case of the broad emission W lamp, +/- 3 nm is typical

* Wavelength precision: better than +/- 0.2 nm

* Wavelength band-pass: <10.0 nm at half height for the W lamp, typical elemental
line emission bandwidth is less than 0.1 nm (Hg, Zn, Cd lamps), 10 nm band-pass
in model VUV-14-D

* Noise and Drift: < +/- 1 X 10 -5 AU (over 30 sec period peak to peak, 1.0 sec
rise time); < +/- 1 X 10-4 AU (over 30 min. period peak to peak, 1.0 sec rise
time) with STD sample cell at constant temperature
