Appendix
Specifications
Wavelength:
190-380 nm standard Deuterium lamp, 380-800 nm with
optional Tungsten lamp.
Wavelength Drive:
Manual drive with mechanical wavelength indicator.
Band Width:
6 nm.
Wavelength Accuracy:
± 1 nm.
Wavelength Precision:
± 0.1 nm.
Optical Methodology:
Standard Deuterium lamp (190-380 nm) and optional
Tungsten lamp (380-800 nm) light sources with concave
holographic grating monochromator with double-beam
optics. Provision for purging the monochromator.
Range Selections:
2.0, 1.0, 0.5, 0.2, 0.1, 0.05, 0.02, 0.01, 0.005, 0.002,
0.001, and 0.0005 AUFS.
Recorder Output:
Single output with 10 mV, 100mV, or 1.0 V full scale
capability with a switch pro10% full scale offset at
each setting.
Integrator Output:
1.0 V/AU analog output, independent of range control but
dependent upon autozero function. A switch supplying an
addi10.0mV is provided on the rear of the unit.
Remote Controls:
Rear Panel input for: autozero, Event Mark, and Remote
Lamp Shut-Off.
Noise:
± 2 x 10
-5
AU from 220-280 nm with 1.0 sec rise time
(static, dry flowcell).
Drift:
< 2 10
-4
AU/hour after 1 hour warmup.
Zero-Adjust:
Autozezro circuit capable of offsetting greater than 1.5 AU
with standard flowcell.
Chart Recorder Filter:
Second Order Bessel filter with four user selected rise
times (0.1, 0.3, 1.0, and 3.0 seconds). Rise time in
seconds approximates 2x time constant in seconds. A
filter bypass switch located on the rear panel provides an
equivalent rise time of 0.1 seconds.
Display:
A 3
½
digit LED displays absorbance and relative sample
and reference light intensities.
