Quick Peaks Gadget

• Accessible from Gadgets menu when a graph is active
• Ideal for graphical analysis of peak data containing a small number of peaks
• Select region of interest on graph to analyze a sub range of plotted data
• Multiple methods for detecting and subtracting baseline
• Option available to fit peaks using available peak functions (OriginPro Only)
• Save settings to Theme for repeat analysis of similar data
• Does not provide batch processing capability

Multiple Peak Fit Tool

• Accessible from the Analysis: Peaks and Baseline: Multiple Peak Fit menu when either worksheet or graph is active
• Ideal for fitting peaks to data with a small number of peaks, where peaks are well separated
• Click and select peak centers, then perform peak fitting with option to switch to NLFit dialog for full control
• Does not provide baseline correction capability

Peak Analyzer

• Accessible from the Analysis: Peaks and Baseline: Peak Analyzer menu when either worksheet or graph is active
