Description£º
WESTINGAREA supplied L542116 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), 308 nm, W lamp: 370 nm to 1000 nm, 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 lamps), 10 nm
bandpass in model UV-540-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
Remarks£º
Price will be negotiable if order quantity is big.
