Creating a Method

Isotope Analysis Acquisition Parameters Dialog Box

Setting Parameters for Isotope Analysis

Because Isotope Analysis is similar to quantitative analysis in Spectrum Analysis,

setting the acquisition parameters is the same. Refer to “Setting Parameters for

Quantitative Analysis” in this chapter to set acquisition parameters for Isotope Anal-

ysis.

NOTE The Full Quant (3) in the Peak Pattern (left bottom) box is better than 1 point on the

Peak Pattern for Isotope Analysis.
