1. To change the detector methods used from DAD to VWD, please remove data in “Found Wavelengths from Scanning Detectors” (~column 181) and reenter the values to the columns directly below, named: “Found Wavelengths for Manual Determination” (~column 185)
  2.  Please note, the values in “Found Wavelengths from Scanning Detectors” must be left blank with no data entered, otherwise it will print the final certificate with DAD methods used.
