Grams 32 5976 An imported file is using the peak tops as peak start and end rather than using the valleys. The file is a Perkin Elmer file converted to ".SPC" format by the PE software. The same file produced by Nicolet is fine. If you look at the PE file in GRAMS it shows as having a Y axis in Transmittance - it should be Absorbance. If you use Trace Information and change the Y axis to Absorbance then save the file it picks peaks properly. Basically the fault would appear to be in the Perkin Elmer conversion software - it apparently gives the wrong axis designation. Grams32 - en
