Functional Description
The Surveyor UV/Vis Plus Detector is a full-featured, time-programmable,
variable-wavelength UV/Vis (ultraviolet/visible) absorbance detector. It operates in either the
single or dual wavelength mode in the UV or visible ranges.
The UV/Vis detector is a benchtop unit for inclusion into the Surveyor Plus LC System. You
control the detector remotely over an Ethernet communications link from a Thermo
Scientific data system computer.
The UV/Vis detector consists of a dual light source, an optical bench (see Figure 2), dual
photodiode detectors, and several printed circuit boards (PCBs).
Figure 2. Surveyor UV/Vis Plus Detector optical bench
To provide a complete spectrum of ultraviolet (UV) and visible light, the detector uses a
deuterium lamp (D2) for the UV range (190 to 365 nm) and a tungsten lamp (W) for the
visible range (366 to 800 nm). The lamp cover has a safety interlock that reduces the
possibility of human exposure to harmful UV light. When you remove the cover, the lamps
automatically turn off. A computer-controlled shutter selects the deuterium lamp for sample
analyses in the UV range and the tungsten lamp for sample analyses in the visible range. The
light from the selected lamp goes to a holographic grating that disperses the light into a
spectrum. The grating turns to select the programmed wavelength. For precise wavelength
control, a stepper motor controls the alignment of the grating. A system of baffles that reduces
stray light in the optical bench increases the absorbance linearity.

1 Introduction
LightPipe Flow Cell
Thermo Scientific Surveyor UV/Vis Plus Detector Hardware Manual 3
From the grating, the light travels to a fiber optic beamsplitter, where a portion of the light is
redirected to a reference photodiode. The signal from the reference photodiode compensates
for changes in lamp intensity and helps maintain consistent performance as the lamp
performance varies. From the beamsplitter, most of the light passes through a lens and then on
through the flow cell and onto the sample photodiode. The analog PC board converts the
intensity counts from the photons falling on the sample photodiode into data that the data
system can process.
Light-emitting diodes (LEDs) on the front of the module provide information about power,
communications, run, and lamp status. See “Status LEDson page 7.
You can order the UV/Vis detector with one of these flow cell options:
Standard analytical flow cell with a 10 mm path length
LightPipe™ flow cell with a 50 mm path length
You can order other flow cells as options for the detector. See Table 5.
LightPipe Flow Cell
The internal bore of the LightPipe flow cell is 50 mm long and has a volume of 10 μL. The
5 cm optical path length produces a signal five times that of a conventional 1 cm flow cell,
while the low internal volume of 10 μL minimizes band broadening. A special low refractive
index coating of the internal bore ensures a high optical throughput and minimizes
short-term noise.
Mobile phase enters the LightPipe flow cell through a port in the bottom of the flow cell and
exits through a port in the top of the flow cell. See Figure 3. Directing the flow from the
bottom to the top of the flow cell reduces the development of air bubbles.

1 Introduction
LightPipe Flow Cell
4Surveyor UV/Vis Plus Detector Hardware Manual Thermo Scientific
Sensitive optical fibers are exposed at both ends of the LightPipe flow cell (see Figure 4).
Thermo Fisher Scientific ships the LightPipe flow cell with end caps (see Figure 5) to protect
these optical fibers. Do not remove the protective end caps until you install the LightPipe flow
cell. If you remove the LightPipe flow cell from the detector, replace the protective end caps
for storage.

Figure 5. LightPipe flow cell with protective end caps
CAUTION Avoid touching the ends of the LightPipe flow cell. Touching the ends of the
flow cell can damage the exposed optical fibers. If you must grasp the ends of the
LightPipe flow cell, wear clean, talc-free gloves.
Note Thermo Fisher Scientific ships two versions of the LightPipe flow cell. Figure 4
shows one version and Figure 21 and Figure 22 on page 29 show the other version.

1 Introduction
Lamps
Thermo Scientific Surveyor UV/Vis Plus Detector Hardware Manual 5
Lamps
The UV/Vis detector has two lamps. The tungsten lamp emits light in the visible region, and
the deuterium lamp emits light in the ultraviolet region. With use, the deuterium lamp emits
less and less light before it fails to ignite (Figure 6). In contrast, the light output from the
tungsten lamp remains relatively constant until the lamp fails.
Figure 6. Deuterium lamp intensity versus lamp usage hours
The deuterium lamp typically requires a warm-up time of 20 to 30 minutes. However, for
applications that demand great sensitivity, allow a warm-up period of 1.5 hours.
The tungsten lamp typically requires only 15 minutes of warm-up time.
The deuterium lamp has a lifetime of approximately 2000 hours and the tungsten lamp has a
lifetime of approximately 2500 hours. Lamp lifetime varies depending on the application.
IMPORTANT The intensity of the deuterium lamp falls off very slightly over a period of
time after it is turned on. Before collecting data in the spectral range of the deuterium
lamp, wait at least 1.5 hours for the lamp to stabilize after a cold start.
Note Turning on the instrument automatically ignites the lamps. If the lamps have been
turned off, you must load a method and wait for the lamps to warm up before you
proceed with a run.
