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.
