The limit of detection (LOD or LoD) is the lowest signal, or the lowest corresponding quantity to be determined (or extracted) from the signal, that can...

esterases. The detection limit of a test is the concentration at which the test starts to turn from negative to positive. Although the detection limit may vary...

the longer the count, for the same system, the better the detection limit. The detection limit, often referred to as the Minimum Detectable Activity (MDA)...

sample that can accurately be measured by an assay (synonymously to detection limit), and "analytical specificity" is defined as the ability of an assay...

used, XPS easily detects all elements except hydrogen and helium. The detection limit is in the parts per thousand range, but parts per million (ppm) are...

being allowed, in practice meaning that any alcohol level beyond the limit of detection will result in penalties. Penalties vary and may include fines, imprisonment...

analytical detection limits. The TLV is a recommendation by ACGIH, with only a guideline status. As such, it should not be confused with exposure limits having...

argued that the second definition, which is closely related to the detection limit, is a better indicator of the performance of a measuring system. To...

allows adulterated and non-basmati strains to be detected, with a detection limit from 1% adulteration upwards with an error rate of ±1.5%. Exporters...

with a special coincidence photon-counting setup. The concept of the detection limit for chemical imaging is quite different from for bulk spectroscopy...

the detection of nitazenes. The drug sample is added to water and requires sufficient solubility for the test to be successful. The detection limit of...

allows detection of minute quantities of a biomolecule. Proteins can be detected down to femtomole quantities, well below the detection limit for most...

SIMS is the most sensitive surface analysis technique, with elemental detection limits ranging from parts per million to parts per billion. In 1910, British...

accepted standard is by using the Raman signal of water. Sensitivity or detection limit is another specification to be considered, that is how little light...

Demarcation Line, a truce border line between North and South Korea Method detection limit, of a chemical substance Fayyad & Irani's MDL method, a discretization...

potentiostat. This device is less sensitive than some others, with a detection limit of 1.9 × 103 CFU/mL. By comparison, some ELISAs range from 20 CFU/mL...

of chemical species present may be extremely low and close to the detection limit of the analytical method. In well managed laboratories, AQC processes...

we conclude that the detection limit for their observing the X-rays of Z = 43 can be 1000 times lower than the 10−9 detection limit for the element Z =...

After detection, the noise is removed. A fourfold improvement in the detection limit can be obtained. Mutual coherence (linear algebra) Signal detection theory...

An intrusion detection system (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations...

sample that can accurately be measured by an assay (synonymously to detection limit), and "analytical specificity" is defined as the ability of an assay...

specific mine or bullion source. Elements that are measured above detection limits can be used for gold fingerprinting and geochemical characterization...

chemistry research is largely driven by performance (sensitivity, detection limit, selectivity, robustness, dynamic range, linear range, accuracy, precision...

process is predicted to be four orders of magnitude shorter than the detection limit of even the most sensitive of radical probes. It has been postulated...

While TCDs are beneficial in that they are non-destructive, its low detection limit for most analytes inhibits widespread use. FIDs are sensitive primarily...

Concentrations shown below range from not detected, or ND, (with the detection limit in parentheses) to 6750 with concentrations in nanograms of PFOA per...

mass spectrometry (SRM-CE/MS), which has a detection limit of 7.3 ng/mL in human plasma and a quantitation limit of 15 ng/mL. This method works with sample...

light. This results in a better signal-to-noise ratio, and lowers the detection limit by approximately a factor 10000, when compared to the 180° geometry...

signal. This technique results in a 100 to 1000-fold improvement of the detection limit, because the capacitive component is effectively subtracted. Qualitative...
