Iolite’s secondary time-resolved window shown here is used to provide a more detailed picture, with as many as twelve different parameters simultaneously displayed versus time.  All raw input channels and all output parameters are available for display, as well as any intermediate channels created by the currently active data reduction scheme.  In this example 15 minutes from a multi-day MC-ICP-MS U-Th data set are shown, being a series of discrete spot analyses traversing a sample of high-uranium calcite.  Of the three time series visible, two have been automatically masked to only appear where the primary channel (238U in this case, shown in grey) is above a user-specified voltage threshold.  All displayed time series have independent Y axes and can be adjusted individually by the user, although scales are only displayed for two of them (the traces designated “Primary” and “Right”).  Any trace can be smoothed as required for display purposes only, leaving the time series itself unaltered (if smoothing of the actual time series is desired, this can be implemented within the DRS).  Square boxes indicate time intervals of the currently selected integration type (in this case an output), and their values for the current Primary trace (box size corresponds to a 2s.e. uncertainty). These time intervals can be created, edited or deleted using a simple on-screen interface.
