Note: Side and top slots in front panel of the unit are designed for tubing and capillaries
accommodation. FEP tubing with outer diameter 1/8” are fitted by pressing into
the slot. Capillaries and tubing with outer diameter 1/16” are fitted using short
FEP tubing with outer diameter 1/8” and inner diameter 1/6”, threaded on the
capillary. A tubing threaded this way cannot be pressed in and it is fitted by
inserting from the side into the slot.
4.2. Door Installation
In order to prevent damage of door hinges, the door is supplied apart. The door should be
slipped on the hinges in opened position, see pictures below.
Door mounting must be easy, no strength needed, otherwise the hinges may get damaged.
4.3. Connection to Power Supply and Connection of Communication
Cables
Plug the power supply cord into the instrument socket on the rear panel. Connect PC via
Ethernet or using RS232. If you are connecting whole system, connect in the same manner also
other units.
4.4. Start of the Unit
Use a switch on the rear panel of the detector for connecting to mains voltage, then switch
on the unit using push button on the front panel. The push button glows red, if power source is off
and green, if power source is on. If power supply is disconnected, the unit remembers last status of
this push button and after power supply reconnection it restores the last status. This can be used
for automatic start in the system with a common switch of power source for whole system of liquid
chromatograph (for example using a multiple socket-outlet with a switch).

6.1. Parameters
Here can be set basic parameters of the detector.
6.1.1. Wavelength
This screen is identical to the screen displayed after pressing key WL. Wavelength can be
set in the range of 190-800(600) nm. Keys with arrows left and right move with cursor and up and
down change value. Press ENTER for confirmation of selected wavelength, it will initiate
wavelength setup. Automatic zeroing (Autozero) is only performed when ENABLE is set in
Menu/Preferences/Signal/Autozero After WL Change.
6.1.2. Time Constant
Time constant represents level of signal filtering and is counted for level 63.5 %. Preset value
is used for both digital and analogue output. Slower (longer) time constant improves overall noise
of the detector output at the price of decreasing response speed. Low values decrease response
speed (response delay –time lag) and change the shape of peaks (they are wider and lower).
Time constant does not have an influence on the peak area size, even if low value widens and
lowers the peek.

Example: narrowest expected peak half width in analysis is 8 s and therefore recommended time constant
is 1 s
For standard chromatographic analysis is usually suitable default value of time constant 1 s.
But it is necessary to reset it for UHPLC applications, where is commonly suggested value 0.05 s.
6.1.3. Sample Rate
This setting determines, how many times per second will be measured signal. Its value is
selected according to speed of running analysis.

for 20 points per peak; coefficient 1.7 was used for conversion of width and half width
Example.: narrowest expected peak half width in analysis is 11 s and therefore minimal recommended
sampling rate is 2 sps (samples per second)
For standard chromatographic analysis is usually suitable default value of sampling rate
10 sps (samples per second). But it is necessary to reset it for UHPLC applications.
Setting high sampling rate results in large data files. Contrariwise too low sampling rate
destroys peak shape and puts inexact its area and height. Recommended setting ensures at least
20-40 data points (samples) per narrowest peak.
6.1.4. Thresholds
Detector enables to do certain actions based on absorbance signal and setting of threshold
values. It is possible to set two values, THRESHOLD A and THRESHOLD B in the range
1 up to 4 AU.
Actions performed based on set threshold values can be set for external interface
in Menu/IO config/Interface.

6.2. Preferences
Here can be optimized detector functions to satisfy any user needs.
6.2.1. Lamp
In each sub menu can be set used lamps, method of their start and eventual preheating.
6.2.1.1. Lamps Use
The unit can be set (only model ECD2800) so, that BOTH LAMPS (deuterium and tungsten
lamp) are always on, or only deuterium lamp (ONLY DEUTERIUM (D2)) and/or only tungsten
lamp (ONLY TUNGSTEN (W)).
6.2.1.2. Preheat Time
Preheating of lamp is performed at first start of light sources after unit start, because of
highest possible accuracy of followed first optical calibration of the unit. Default value is 10 s.
The preheat time can also be used for enforcement of general stabilization of the unit before
measurement. It is not possible to perform measuring before lamp is preheated. Preheating can be
skipped using key ESC.
6.2.1.3. Auto Turn On Mode
The unit can be set in a mode that immediately after unit start the light sources are
automatically turned on. In mode OFF the lamps are not turned on after unit start, in mode ON the
lamps are started automatically. Default value is OFF.
6.2.2. Cell Temp
This mode is not used so far.
6.2.3. Display
6.2.3.1. Brightness
The display brightness can be set in eight levels, where value 8 is maximum brightness.
6.2.3.2. ABS Units
Units displayed can be set to AU, mAU and mAU without initial digits (mAU ZEROS
SUPPRESSION). This setting does not influence analogue nor digital output.
Absorbance is measured in relative absorbance units. It does not refer to 1 cm optical path
length. Absorbance measuring range is <−0.2; 4.0> AU for negative dynamic range NORMAL and
<−0.8; 3.0> AU for negative dynamic range HIGHER. It can be set in Menu/Preferences/signal.
6.2.3.3. ABS Precision
For setting number of displayed digits of absorbance.
6.2.4. Sound
Sound signals of the unit can be set as follows:

SOUND SETTING
Setting
Description
KEYBOARD
At each touch of button will be generated short beep when
the key does not have any significance at the moment, mid-
length beep for value change and moving in menu and longer
beep for confirmation of value changes.
ERRORS
At error occurrence will be generated sound signal of the
error. Three consecutive longer beeps in case of an error and
in case of a fatal error with repetition every 5 s. Repetition
can be interrupted by pressing any key.
WARNINGS
At warning occurrence will be generated sound signal of
warning. Three consecutive shorter beeps.
OPERATIONS
During operation will be generated longer beep and for long
operations may be this beep generated at the beginning and
at the end of an operation.
6.2.5. Cooling
Setting method of cooling is essential for detector drift and less essential for its noise. Final
result of its behavior is always dependent on surroundings and therefore needs experimental
attestation for given environment. It is necessary only for reaching the best result in highly sensitive
applications. For common use, the default setting is sufficient.
Lower rotation speed of fans decreases the noise (sound) level in laboratory, but increases
working temperature of illuminator. The lower the illuminator temperature is, the better is the
stability and working parameters of the unit. Recommended range of working temperature is
30-50 °C.
Diagnostics of cooling status is done in Menu/Diagnostic/Cooling, where are displayed actual
measured values of cooling system.
6.2.5.1. Fans Mode
Here can be set method of optical block cooling using fans. Selectable options are OFF,
CONSTANT VOLTAGE, CONSTANT SPEED and CONSTANT TEMPERATURE.
Mode OFF Total shutoff is not recommended. Setting of these modes is preceded in further
points.
6.2.5.2. Fans Voltage
Fans are controlled by constant adjustable voltage (default value is 8 V). Suitable for air-
conditioned laboratories, most stable fans run, but it is impossible to reach lowest rotation speed.
Default mode is cooling.
6.2.5.3. Fans Speed
Here can be set constant speed of fans (default value is 4000 rpm). Setting is a sum of
rotation speed of both fans. Suitable for reaching very low rotation speed. Speed control can cause
slightly unstable run.
6.2.5.4. Illuminator Temp
Constant illuminator temperature is maintained by variable rotation speed of fans. However,
they can cause higher detector noise, which can slightly react to rotation speed regulation. For not

ECD2800 /ECD2600
19 / 47
air-conditioned laboratories the best solution (default value is 40 °C). Recommended setting for
surrounding temperature under 25 °C is 36 °C, and 40 °C for surrounding temperature over 25°C.
Best method to find suitable temperature is to set constant voltage to default value (8 V) and add
2°C to measured temperature after stabilization. Great influence on illuminator temperature has
turned on/off halogen light.
6.2.6. Opti Filter
Optical filters are placed at the front of monochromator before diffraction grating. They are
used to suppress second order on the grating, where for example when setting wavelength 400 nm
grating generates second order of wavelength 200 nm. This wavelength is in automatic mode
filtered by white cut-of filter, which absorbs all wavelengths lower than 340 nm.
SETTING OF OPTICAL FILTERS
Setting
Description
AUTOMATIC
Setting without filter is used for wavelengths under 360 nm,
white filter (WHITE) is used for wavelengths in range of
361-580 nm. Yellow filter (YELLOW) is used for wavelengths
over 581 nm. At this setting is not inserted any filter for test
scans. Recommended and default setting.
NONE
None filter is inserted. All light goes through.
WHITE
White filter is inserted. It absorbs wavelengths under 300 nm.
YELLOW
Yellow filter is inserted. It absorbs wavelengths under
480 nm.
Standardly is set automatic mode. Others are used only during diagnostics.
6.2.7. Leakage
Leakage sensor contains reference and measuring sensor. If the measuring sensor is
immersed in liquid, sensor generates a signal. Signal processing is depending on actual setting.
SETTING OF LEAKAGE SENSOR BEHAVIOR

6.2.8.2. Autozero After WL Change
Here can be set autozero after change of wavelength by key WL or
in Menu/Parameters/Wavelength. ENABLE is set (Autozero is allowed) or DISABLE is set
(Autozero is not allowed). Default setting is ENABLE.
Autozero is not performed after change of wavelength with up/down arrows when ENABLE
is set.
6.3. Control
6.3.1. Optical Recalib
Calibration of optical unit is runs over after first start of light sources after unit switch-on, or it
can be initiated from this menu. If light sources are off and consequently turned on without unit
shutoff, optical unit calibration is not undertaken.
During optical unit calibration is set and controlled spectral setting of detector (wavelength).
Calibration of wavelength is based on spectral lines of hydrogen (656 nm and 486 nm) produced
by emission of deuterium lamp. First point of calibration (0 nm) is finding maximum light on zero
order (grating works as a mirror). Subsequently is found maximum light on spectral line 656 nm
and thereby is the detector calibrated. Verification of setting is done on spectral line 486 nm and if
it is not correct, detector displays a warning. At the end of calibration is performed autozero and
eventual deuterium lamp turnoff. If the use of tungsten light is set in detector menu
(Menu/Preferences/Lamps/Lamps use) than even in spite of that deuterium lamp is turned on
