The Limits of Sensitivity – Living 4 Myself

Figure 4792c shows the SEM-EDS lower limits of detection (LLD) of Cr and Fe in glass (oxide) as a function of spectrum acquisition time. The detection limits can be improved at the beginning of increasing acquisition time but cannot do with further time increase.

The sensitivity should be differentiated from the detection limit

Sensitivity/Detection Limit of EDS - GlobalSino

Bit Error Rate (BER) is the sensitivity benchmark for digital modulation systems. Eb/No is the ratio of the Energy per bit (Eb) to the noise spectral density (No - the noise power present in 1 Hz). The carrier to noise ratio required for a certain BER is a function of the Eb/No of the signal. This is a digital system representation of signal to noise ratio. Each digital modulation type has a Eb/No curve (Eb/No vs. BER). In order to determine sensitivity, use the appropriate curve and find desired bit error rate to determine the necessary Eb/No. Then calculate the Carrier to noise ratio by the following relationship:

It is important that the relevant experimental conditions corresponding to sensitivity measurement should always be stated. These include in a typical case details of the instrument type, bombarding electron current, slit dimensions, angular collimation, gain of the multiplier detector, scan speed and whether the measured signal corresponds to a single mass peak or to the ion beam integrated over all masses. Some indication of the time involved in the determination should be given, e.g. counting time or band width. The sensitivity should be differentiated from the .

Figure 4792b shows the comparison of the relative MDMs, obtained from 50 nm SrTiO3 TEM specimen, versus analysis time t by EDS with a Si(Li) detector and a large SDD detector, and by EELS. This SDD detector had a total active area of 120 mm2, [4] resulting in even better MDM than that of EELS. Furthermore, in general, the techniques are more sensitive to the elements if the detection time is longer.

The PROC FREQ approach is shown below. Begin by obtaining the risk difference and its standard error from PROC FREQ. Since the table is arranged so that Test=1, Response=1 appears in the upper-left (1,1) cell of the table, the Column 1 risk difference is needed. The following ODS OUTPUT statement saves the Column 1 risk difference in a data set.

There are a number of different "detection limits" that are commonly used

Confidence intervals and tests (asymptotic and exact) for these statistics can be computed using PROC FREQ by selecting the proper row or column from the original table. The BINOMIAL option in the TABLES statement provides asymptotic and exact confidence intervals and an asymptotic test that the proportion equals 0.5 (by default). The BINOMIAL option in the EXACT statement provides all of this plus an exact test of the proportion. You can test against a null value other than 0.5 by specifying in parentheses after the BINOMIAL option. For example, tests against the null value of 0.75.

The (NNT) can be estimated in various ways. Since NNT is equal to the reciprocal of the risk difference, one way is to obtain the risk difference estimate and standard error from PROC FREQ and then use the delta method to obtain a standard error and confidence limits for NNT. Alternatively, a modeling approach could be used by fitting a logistic model and estimating the appropriate nonlinear function of the logistic model parameters.
