4 Using the control module

last column is automatically adjusted; if the percentage of the last

compound is already zero, the value of the currently entered

component is adjusted instead. The flow rate of a compound is

calculated by multiplying the overall flow rate (indicated in the Flow

column) by the corresponding percentage divided by 100.

Flow [ml/min]

Indicates the overall flow rate through the column. The entered value

applies to the time specified in the corresponding row.

Graph

The graph depicts the percentage of components as a function of time

together with the overall flow rate. Data are taken over from the Gradient

Table . Changes effected in this table are immediately reflected in the

graph. Legend in the header of the graph indicates the assignment of

colors to individual components. The assignment is fixed and individual

components are displayed in the graph from bottom to top. The flow rate is

displayed as a black line.

The graph has two vertical axes: the axis on the left refers to the mixing

ratio, the one on the right to the overall flow rate.

Parameters

Standby Flow

Sets the overall flow rate through the column in the STANDBY state

reached after the last row of the table has been performed and the

time period defined in the Time to Standby field has passed. The

duration of this state is defined by the Standby Time item. The ratio of

individual components in the respective STANDBY and IDLE states is

given by the first row of the Gradient Table (the Initial row).

Time to Standby [min]

Indicates the time during which the flow rate and mobile phase

composition changes continuously between the last values entered in

the table and the values defined by Standby Flow field and the Initial

row mobile phase composition.

This time is included in the analysis time (the Instrument is in the

CONTROL state). In case when the Time to Standby is zero, there is

step change from flow and components percentage specified on the

last row of gradient table to that specified for STANDBY state.

Standby Time [min]

The time during which the flow rate is maintained at Standby Flow .

This time is included in the analysis time (the Instrument is in the

CONTROL state).

Initial - Standby

The Shimadzu LC-10/20 Pump control module doesn't support this

option.
