Atomic Concentration Quantification based on TAGS with Error Estimates
Quantification
using tags allows a survey spectrum to be used to obtain an elemental
quantification of a sample based on regions while narrow scan spectra
identified with these regions defined on the survey data provide chemical state
information for the quantification table.
There are
two reasons why quantification using tags is preferable to direct
quantification of data:
1. Provided the survey acquisition mode
is well characterised in terms of intensity calibration, reliable
quantification of a sample can be obtained without the need to similarly
intensity calibrate the higher resolutions modes used to acquire narrow scan
spectra aimed at extracting chemical state information about the sample.
2. Error estimates in terms of atomic
concentration can be calculated for both the survey spectrum regions and also
the chemical state information gathered from the narrow scan spectra.
1. Define regions on a survey spectrum
2. Prepare peak models for high resolution spectra
5. Generate Error Estimates for the quantification items
included in the report
6. Check the Noise in the Data is Modelled
by Poison Statistics
7. Export the quantification report to a spreadsheet
