ADC accuracy

(http://purl.allotrope.org/ontologies/property#AFX_0001103)

synonyms: accuracy

An ADC has several sources of errors. Quantization error and (assuming the ADC is intended to be linear) non-linearity are intrinsic to any analog-to-digital conversion. These errors are measured in a unit called the least significant bit (LSB). [Wikipedia]

ADC sampling rate

(http://purl.allotrope.org/ontologies/property#AFX_0001104)

synonyms: sampling frequency, sampling rate

The analog signal is continuous in time and it is necessary to convert this to a flow of digital values. It is therefore required to define the rate at which new digital values are sampled from the analog signal. The rate of new values is called the sampling rate or sampling frequency of the converter.

The carrier gas linear velocity affects the analysis in the same way that temperature does (see above). The higher the linear velocity the faster the analysis, but the lower the separation between analytes.

The linear velocity will be implemented by means of the carrier gas flow rate, with regards to the inner diameter of the column. [Wikipedia]

A quantitative measure for nuclear spin-spin, nuclear-electron (hyperfine coupling) and electron-electron (fine coupling in EPR) coupling in magnetic resonance spectroscopy. The 'indirect' or scalar NMR coupling constants are in a first approximation independent of the external magnetic field and are expressed in Hz. [IUPAC Gold Book]

cross-validation

(http://purl.allotrope.org/ontologies/property#AFX_0000618)

synonyms: cross validation

The value of a cross-validation. Cross-validation is a comparison of validation parameters when two or more bioanalytical methods are used to generate data within the same study or across different studies. An example of cross-validation would be a situation where an original validated bioanalytical method serves as the reference and the revised bioanalytical method is the comparator. The comparisons should be done both ways. [FDA]
