Setting up Low and High Amount Limits for Calibration Standards

Setting up Low and High Amount Limits for

Calibration Standards

You may specify low and high amount limits in the calibration table. If the

calculated amount is outside the limits, a warning appears in the report. The

amount limits can be used as qualifiers to confirm the peak identification.

Compounds that are outside of the amount limits, are not used to recalibrate the

Calibration Table. The minimum and maximum amounts limits do not consider a

multiplier value that you may have specified.

1) From the Calibration menu, select Calibration Table Options..., then

Compound Details or change from Overview to Compound Details in the

drop box located in the middle of the window.

2) Click in the box presented to the left of the Low Limit column while in the

biphenyl row. Now click in the Low Limit cell. A lower limit is

automatically calculated. This is a lower limit of -20%.

3) Click in the box presented to the left of the High Limit column while in the

biphenyl row. An upper limit will appear in the cell. This is an upper limit of

+20%. The default is +/- 20%, but you may set any desired limits.

4) Repeat this procedure for the o-terphenyl peak.

5) Resave your method.
