desorption

(http://purl.allotrope.org/ontologies/property#AFX_0000450)

Desorption is a phenomenon whereby a substance is released from or through a surface. The process is the opposite of sorption (that is, either adsorption or absorption). This occurs in a system being in the state of sorption equilibrium between bulk phase (fluid, i.e. gas or liquid solution) and an adsorbing surface (solid or boundary separating two fluids). When the concentration (or pressure) of substance in the bulk phase is lowered, some of the sorbed substance changes to the bulk state. [Wikipedia]

The focal distance is the optical distance from the point of convergence of rays of light to the digital sensor at the focal plane in a camera. It is a measure of the angle of view and the magnification. A long focal length has a narrow angle of view and high magnification. A short focal length has a wide angle of view and low magnification.

force

(http://purl.allotrope.org/ontologies/property#AFX_0000420)

In physics, a force is any interaction that, when unopposed, will change the motion of an object. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described by intuitive concepts such as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of Newtons and represented by the symbol F. [Wikipedia]

An analog-to-digital converter is a device that converts a continuous physical quantity to a digital number that represents the quantity's amplitude. The conversion involves quantization of the input, so it necessarily introduces a small amount of error. Instead of doing a single conversion, an ADC often performs the conversions periodically. The result is a sequence of digital values that have been converted from a continuous-time and continuous-amplitude analog signal to a discrete-time and discrete-amplitude digital signal.

In statistics, the Pearson product-moment correlation coefficient (sometimes referred to as the PPMCC or PCC or Pearson's r) is a measure of the linear correlation between two variables X and Y, giving a value between +1 and ?1 inclusive, where 1 is total positive correlation, 0 is no correlation, and ?1 is total negative correlation. It is widely used in the sciences as a measure of the degree of linear dependence between two variables. [Wikipedia]

retention factor

A measure of the time the sample component resides in the stationary phase relative to the time it resides in the mobile phase; it expresses how much longer a sample component is retarded by the stationary phase than it would take to travel through the column with the velocity of the mobile phase. Mathematically, it is the ratio of the adjusted retention volume (time) and the hold-up volume (time): k = V'_R / V_ M = t'_R / t_ M If the distribution constant is independent of sample component concentration, then the retention factor is also equal to the ratio of the amounts of a sample component in the stationary and mobile phases respectively, at equilibrium: k = [amount of component in stationary phase] / [amount of component in mobile phase]. If the fraction of the sample component in the mobile phase is R, then the fraction in the stationary phase is 1 - R; thus k = (1 - R) / R. [IUPAC]

specification

(http://purl.allotrope.org/ontologies/property#AFX_0000800)

Quantitative and qualitative declaration (tolerance) that describes a property or characteristic (e.g. repeatability, nonlinearity) of a (measuring) instrument. Sometimes, a differentiation is made between guaranteed and typical specifications. The value of the characteristic that is measured on the individual instrument must usually conform to the guaranteed specification after installation and after maintenance work (Equipment Qualification). A typical specification is based on the value attained by a large number of instruments. However, this value need not necessarily be matched by all instruments. With the assistance of the specification, an instrument’s suitability for its intended use can be evaluated before it is purchased (Design Qualification). A specification is usually stated as a (usually two-sided) tolerance interval (e.g. nonlinearity), or as a standard deviation (e.g. repeatability). [DOWT]

Value of (m/z)/Δ(m/z) measured for two peaks of equal height in a mass spectrum at m/z and m/z ±Δ(m/z) that are separated by a valley which at its lowest point is 10 % of the height of either peak. For peaks of similar height separated by a valley, let the height of the valley at its lowest point be 10 % of the lower peak. Then the resolution (10 % valley definition) is (m/z)/Δ(m/z) and should be given for a number of values of m/z. [IUPAC]

synonyms: calculated efficiency, column efficiency, number of theoretical plates

Theoretical plates is a concept for the description of column efficiency. The number of theoretical plates (N) is an indirect measure of peak width for a peak at a specific retention time. Columns with high plate numbers are considered to be more efficient (i.e., higher column efficiency) than columns with lower plate numbers. A column with a high number of plates will have a narrower peak at a given retention time than a column with a lower number of plates. [Agilent] N=16(tR/w)² or N=5.54(tR / wH)² where tR is the retention time, w is the width of the peak and wH is half the width of the peak.
