I am using Peak detection VIs for Gas Chromatography. (Peaks 3.0.llb) The peak detection VIs have a bug that causes fatal crashes in LabVIEW 6. Any suggestions on other code sources for peak detection (with a noisy baseline) and peak area measurements?

Is this the same set of VI's that you are using?

As far as I can tell none of the VIs offered by NI currently are able to fit a baseline and measure the area of a peak. The VIs I am using were last revised in 1995 and were never offered as part of the LabVIEW package. They were created by NI. I have been using them to analyze Gas Chromatography data.

They would be a nice addition to NI's standard library.

Does the example that you attached always crash on your machine? I ran it on LabView 6 and didn't have a problem.

products.

However, I can get it to crash reliable by putting it in a loop and sending it a signal from a signal generator.

Any suggestions on other code sources for peak detection (with a noisy baseline) and peak area measurements?Hey does anyone know how to "wire" a VI like this one to read analog voltage data from a FP-AI-110 module?  The detector I am using is a Brooks Rand and gives output data as a DC voltage signal.
