Ellvin displays a chromatogram from sample analysis data. In Analyze Window, Ellvin retrieves analysis data stored on the user’s
computer. In addition to all of the features in Live Data Window, the following features are available in Analyze Window:
Integrator 1
The
user
creates a baseline and integrates peaks, then calculates the peak height and area to determine analyte
concentrations. Beginning and ending points of the integration are based on the cursor position.
Integrator 2
With Integrator 2, Ellvin snaps to the vertical point on the data line closest to the cursor position.
Integrator 2 is recommended for ease of use.
1.
Based on retention times, determine which peak(s) to integrate.
2.
Click and hold the mouse at the valley before the first peak to integrate (In figure below: Valley 1).
3.
Drag the mouse to the valley after the peak to integrate (In figure below: Valley 2). Do not drag the line through the peaks. A
highlighted area displays the integrated peaks.
4.
When the integration is complete, a black line appears and the data grid reports the results.
Auto Analyze
The Auto Analyze tool integrates all the peaks present.
