Comparison without using endPoint detection
Foraminifera are frequently used as archives of geochemical signals that
are used in proxy measurement reconstructions. Ecological evolutionary
responses can be tracked and sea surface temperatures can be
reconstructed with calibrated equations using a ratio of magnesium to
calcium as an input, making this Mg/Ca (mmol/mol) a popular geochemical
measurement1, 6.
When processed without the endPoint function and the integration time
was between 35 – 80 seconds elapsed, the median24Mg/44Ca ratio of Foram-72-shot-3
was 4.37±2.10 mmol/mol and when processed with the endPoint function
with an integration time of 6 seconds was 2.46±1.35 mmol/mol. Use of the
endPoint function thus increases accuracy (by focussing on the
geochemical target) and also increases precision through higher quality
sample data for statistical analysis.
