ICP-MS Calculator

This web application is designed to process ICP-MS calibration and sample data from Excel files. To use it, download the template file, fill in your calibration and sample measurements, then upload it here to calculate results and generate a calibration curve.

Notes:

  1. If a sample blank is missing, the app will prompt to use the calibration blank as a substitute. if no override is selected, processing will fail.
  2. If the calibration blank labeled 2%HNO3 is missing, the app will assume a blank intensity of zero and skip substrate background correction. The calibration blank is used for background correction in calibration data.
  3. Uncertainty Estimation:
    • Regression Error: Based on how well the calibration curve fits the data. This reflects the statistical uncertainty in the slope and intercept.
    • RSD-Based Error: Calculated from the relative standard deviation (RSD%) of the signal and internal control. This accounts for instrument and sample variability.
    The total uncertainty is calculated by combining both sources of error using standard error propagation rules.
