Detection limits should be a thing of the past in gamma-ray spectrometry in general as well as in neutron activation analysis

In gamma-ray spectrometry with high-resolution detectors, full-energy peaks are often to be detected by a peak-search algorithm, with a threshold for detection. Detection limits can be derived from this. Detection limits are often computed along with measured activities or concentrations. When an analyte is not detected, the detection limit...

Assessment of detection limits in viral diversity studies using 454 amplicon sequencing

Background Next-generation sequencing enables to detect sequence diversity in populations of viruses, an essential step in the development of drug mixtures to combat viral infections. The process of sequencing patient samples using bidirectional Roche 454 amplicon sequencing technology, as implemented at the Delft Diagnostic Laboratory (DDL),...

Assessment of detection limits of fiber-optic distributed temperature sensing for detection of illicit connections

Distributed Temperature Sensing (DTS) with fiber-optic cables is a powerful tool to detect illicit connections in storm sewer systems. High frequency temperature measurements along the in-sewer cable create a detailed representation of temperature anomalies due to illicit discharges. The detection limits of the monitoring equipment itself are...
