A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value.
The ion source converts and fragments the neutral sample molecules into gas-phase ions that are sent to the mass analyzer. While the mass analyzer applies the electric and magnetic fields to sort the ions by their masses, the detector measures and amplifies the ion current to calculate the abundances of each mass-resolved ion.
Laboratory quality control is designed to detect, reduce, and correct deficiencies in a laboratory's internal analytical process prior to the release of patient results, in order to improve the quality of the results reported by the laboratory.
In many laboratories, it is the original place of record of data (no copying is carried out from other notes) as well as any observations or insights. For data recorded by other means (e.g., on a computer), the lab notebook will record that the data was obtained and the identification of the data set will be given in the notebook. [ 4 ]
Quality control begins with sample collection and ends with the reporting of data. [4] AQC is achieved through laboratory control of analytical performance. Initial control of the complete system can be achieved through specification of laboratory services, instrumentation, glassware, reagents, solvents, and gases.
An amplicon sequence template that has been prepared for amplification. The target sequence to be amplified is colored green. In molecular biology, an amplicon is a piece of DNA or RNA that is the source and/or product of amplification or replication events.
For simple inline formulas, the template {} and its associated templates are often preferred. The following comparison table shows that similar results can be achieved with the two methods. The following comparison table shows that similar results can be achieved with the two methods.
