  AMS (LA-ICPMS data reduction software) Release Notes Scott Mutchler (srm@vt.edu) Fri Sept 8, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Added logging (configured by logging.properties file) of calculation values, errors, etc. * Fixed LOD calculations (the formula was using the wrong concentration) * Changed report so that if calculated concentration is less than LOD the text "< LOD" is reported and not the concentration. * Changed drift correction so that if R squared < CI for each element the nearest standard run (in time) is used (no correction applied) * Modifed chart panels so that they have a splitter bar under the chart so it can be resized * Added datapoint of sample time to drift plots * Changed open dialog to remember last directory when selecting spectra files * Added combo box to specify Counts/Counts Per Second (choosing CPS sets the dwell time to 1 second) Not implemented yet: * Choosing the integration region using the mouse (I'm still working on the best way for this to work) Monday Oct 2, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Added ability to use Raman spectrum of water (for fluid inclusions) to determine salinity and absolution concentrations (Mernaugh 1989). Can be used instead of microthermometry. Thursday Oct 12, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- I've made a lot of changes (for the better I hope :) * The host correction factor calculation has been fixed (it was using a wrong concentration) * There is a new tab to specify the host concentrations so that the host correction is automatic now (you can enter concentrations in ppm or wt % oxide) * When loading a ICPMS data file you get prompted with a dialog to choose the elements/isotopes to include in the analysis (duplicates masses for an element result in the last isotope being used) * XY Mapping - If your sample spectrum has multiple data points, you can specify the number of points in X/Y. AMS will output an R (www.r-project.org) script to plot results as a graph or contour map (along with other goodies!) * Output options - You can specify if you want a preview window or Excel output files (or both). * Results now have a column for the mix and host concentrations (when apply host corrections) * New tabs were added to the spectrum tabs to allow you to edit the data for each element (remove noise spikes, etc.) Friday Oct 13, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Updated mass_conversions.xml and la_icpms_standards.xml data files with updated values from Marcel Guilong. It contains updated values for NIST 610 and GSE-1G. Thanks, Marcel. * Added "Use Current Analysis" button to host concentration tab. If you click this, the concentrations from the last run analysis will be used for host concentrations. Tuesday Oct 17, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Replaced buttons with menu items/toolbar (Save/Open/New are not implemented but will be soon) * Fixed memory leak (window closing left orphaned javaw.exe process) Monday Oct 23, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Fixed normalization to XX% oxide for analyses with host corrections. If you normalize to 96%, the mix is normalized to 100-correction_factor*(100-96). This is necessary because the host is assumed to be 100% non-volatiles. These results have been verified. * Added new look-n-feel to AMS (Office2003 look) * Modified drift correction to take into account long running analyses (or multiple analyses in a single file) * Enabled the New button. You can reset the AMS interface by clicking New. Thursday Oct 26, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Added fractionation plots (Concentration vs % Signal Integrated); no correction is applied at this point * Auto-picking of background region is now more intelligent (starts 10 seconds before actual signal) Wednesday November 1, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Added new AMS.exe (Java execution wrapper for easier launching on Windows) Tuesday Nov 7, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Fixed problem where drift correction was introducing a NaN value that caused LOD and concentrations to sometimes be zero Thursday Nov 9, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Added Save, Save As and Open features finally. You can save your entire analysis to an .xml file and reload it at anytime. You don't need your original files. Look at the melt inclusion example included in the distribution: AMS\samples\melt_inclusion\ar21b03.xml. * Changed fractionation plots to have time (into integration) instead of % integration. Tuesday Nov 28, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Added support for up to 3 different standard runs (e.g. 610,612,614). This allows you to minimize error due to non-linearity in detector response (i.e. P/A factors) with concentration/signal intensity. * Fixed and validated LOD calculations to use formula in Longerich 1996 * Reorganized user interface and output report * Added status bar to AMS window * Changed tables so you can SHIFT+CLICK to select multiple rows (CTRL+C will copy data into clipboard) * Added data table tab to drift/fractionation plots so you can extract the data Thurday Dec 7, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Added standard values for NIST 610/612 from published data for Pearce et al and Normal et al (for comparision to LAMTRACE) * Added Excel file explaining the source of NIST 610 values (from multiple published sources) * Added Reset button to clear host correction factors * Did some memory optimizations (hopefully this will reduce the amount of RAM AMS uses) * Input files are now read with actual creation dates (not modified dates); this only works for US computers running Windows Friday Dec 8, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * You can now perform analyses with multiple isotopes. Of course, this only makes sense when you perform a calculation with the known concentration method. * All elements are sorted by mass (not alphabetically). * Fixed problem with creation dates being read from ICPMS files Monday Dec 18, 2006 ---------------------------------------------------------------------------------------------------------------------------------------- * Fixed some minor bugs * Changed output to not report concentrations below LOD (left blank intentionally; I wanted to report <LOD but I didn't want to change the cell to a string type) * Added standard fractionation plots (plots intensity ratio of element to standard element) for each standard run Tuesday Jan 2, 2007 ---------------------------------------------------------------------------------------------------------------------------------------- * Added GeoReM preferred values for NIST 614 as a new standard * Changed "Standard Fractionation Plots" tab to "Standard Element Ratio Plots" March 30, 2007 ---------------------------------------------------------------------------------------------------------------------------------------- * Fixed several bugs where concentrations were being calculated as zero * Fixed screen resizing issues July 1, 2008 ---------------------------------------------------------------------------------------------------------------------------------------- * Lowered minimum R-squared for drift correction from 0.9 to 0.3 * Fixed error in halite dissapearance formula (NaCleq is now correct) * Time stamps are now read directly from the 3rd line of Agilent data files (does not use modified date of data file anymore)
