you have selected a solution in a titration or dosing command then the cyl-
inder volume will be checked in the sequence.
Cylinder serial number
8 characters, [ 'empty' ]
Serial number of cylinder. It is printed on new cylinders. With intelligent ex-
change units it is read off automatically. It can be altered at any time, e.g. if
the cylinder has to be replaced.
Parameters for preparation
Configures the parameters to be used in the command PREP .
Volume
0.00000 ... 99999.99999 mL, [ cylinder volume ]
Volume to be dosed in during preparation. With Cylinder volume the whole
contents of the cylinder will be dosed in.
Cycles
1 ... [ 2 ] ... 9
Number of rinsing cycles during preparation.
Dosing rate
0.01 ... 150.00 mL/min, [ maximum ]
Speed at which the solution is to be dosed. The maximum dosing rate de-
pends on the cylinder volume of the exchange unit used (see below). When
the function is carried out the speed will automatically be reduced to the
largest possible value.
Filling rate
0.01 ... 150.00 mL/min, [ maximum ]
Speed at which the cylinder is to be filled. The maximum filling rate de-
pends on the cylinder volume of the exchange unit used (see below). When
the function is carried out the speed will automatically be reduced to the
largest possible value.
Maximum Dosing/Filling rate for exchange unit as a function of the cylinder volume:
Cylinder volume Maximum rate
1 mL 3.0 mL/min
5 mL 15.0 mL/min
10 mL 30.0 mL/min
20 mL 60.0 mL/min
50 mL 150.0 mL/min
Note
Enter lower rates for high-viscosity liquids.
Tubing parameters
Defines the length and diameter of the tubing connected to the exchange unit.
Note
Default values have already been entered for the tubing parameters; these cor-
respond to the dimensions of the standard tubing supplied. If you do not make
any alterations to the tubing connections then you do not need to alter the tubing
parameters. For information on length und diameter of other tubings see
