Report Variable (Peak Table)

Type:

Fixed point number

Dimension:

Minutes

Value Range:

0 ... 999.999 [min]

Default:

0 (no function)

Related Parameters:

Retention Time

Description:

Normally, peak integration is performed automatically. It is possible to limit or extend integration on the left, right, or on both sides with the appropriate peak table parameters. This may be done in the peak table via a left and/or a right limit.

Function:

The peak is integrated between left and right limit, that is, between:

t - LL ... t + RL

Where:

t = Retention Time

LL = Left Limit

RL = Right Limit.

The value 0 disables the limitation.

Example 1:

For the right and left integration limits, the value 0.5 min is entered. The peak maximum is at the retention time of 8 min. The peak is integrated from 7 min 30 s to 8 min 30 s.

 Note:

The LL and RL limits can also be enabled/disabled independently.

Example 2:

For the left integration limit, the value 0.5 min is entered. For the right integration limit, the value 0 is entered. As before, the peak maximum is at the retention time of 8 min. The peak is integrated from 7 min 30 s. The end of integration is automatically determined then.
