Resolution, Sensitivity, and Precision Typical Values

The following information lists the typical analytical performance limits for new instruments using installation setup parameter settings/conditions.

Resolution

This test measures the peak width of a suite of analytical lines distributed over the surface of the chip and compares them to a specification. This test requires an analysis to be run and the multi-element standard and blank solutions. The Instrument Performance test software will use the data from the generated worksheet to calculate the Full Width at Half Maximum - FWHM (that is, the width of the peak at half its height). Results are generated and displayed in the Instrument Performance test results.

Sensitivity (Signal to Background Ratio - SRBR)

Signal to Background ratios are calculated using SRBR = (Total intensity - blank intensity) / Square Root blank intensity)

Precision

Precision is 10 replicates of sample readings on the multi-element standard.
