Biotage ELSD-1080
3.3.5.2 RUN
The RUN mode is the detector’s operational mode. In this mode
the detector is controlled at the set temperatures and gas flow,
and the system is fully operational. During heating or cooling the
detector will display
NOT READY to show the system has not
reached the set conditions. When the detector has equilibrated
READY will be displayed and the detector is ready for use.
3.3.6 Error Conditions
The Biotage ELSD-1080 detector is equipped with a number of
sensors and error checking facilities to ensure safe operation. If
an error is detected the detector gives an audible warning and
a visible description of the error condition. In event of any error
condition, the unit defaults into the STANDBY mode in which
the heaters, LED & gas are turned off. A complete list of
detector errors and remedial actions are given in the
troubleshooting section of this manual.
3.3.7 Clearing an Error
Once the source of the problem has been corrected, the error
message will be cleared automatically on the detector display
and remain in STANDBY mode. Select RUN mode to put the
ELSD back into its operational state. If the problem has not
been rectified the ELSD will repeatedly error when RUN mode
is selected.
3.4 Operational Parameters
3.4.1 Method
The Biotage ELSD-1080 detector has the capacity to store 10
custom definable methods in memory. These methods
comprise, evaporator & nebulizer temperature and gas flow,
which can be optimized for specific applications.
These 10 on-board methods are selected using the front
keypad and screen, via the METHOD option. The Method Editor
Software utility (page 39) is required to edit and download the
custom methods.
In addition to the 10 on-board methods, the ELSD-1080 has a
method XXX that allows modification of the ELSD parameters
to be made without the need for software control. Method XXX
allows the detector to be used in standalone mode via the front
screen and keypad.
3.4.1.1 Loading a Method
To load one of the 10 on-board methods, highlight METHOD .
Using the
cd
keys scroll up or down to the required method
number. The detector will acknowledge the change by
displaying the method number in the top left hand corner.
Editing of this method is prohibited via the front keypad; this
can only be carried out using the Method Editor Software (see
Section 3.5.4 page 39). The detector is pre-loaded with 10
methods at the factory, as detailed in Table 4.
