  2. High-performance liquid chromatography - Wikipedia

    en.wikipedia.org/wiki/High-performance_liquid...

    This method is much more convenient. However, convenience comes at the cost of specificity and coverage of a wide range of drugs, therefore, HPLC has been used as well as an alternative method. As HPLC is a method of determining (and possibly increasing) purity, using HPLC alone in evaluating concentrations of drugs was somewhat insufficient.

  3. Charged aerosol detector - Wikipedia

    en.wikipedia.org/wiki/Charged_Aerosol_Detector

    The charged aerosol detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer.

    Analysis of buprenorphine, a heroin substitute, demonstrated the potential utility of multidimensional LC as a low-level detection method. HPLC methods can measure this compound at 40 ng/mL, compared to GC-MS at 0.5 ng/mL, but LC-MS-MS can detect buprenorphine at levels as low as 0.02 ng/mL. The sensitivity of multidimensional LC is therefore ...

  6. Area under the curve (pharmacokinetics) - Wikipedia

    en.wikipedia.org/wiki/Area_under_the_curve...

    The use of trapezoidal rule in AUC calculation was known in literature by no later than 1975, in J.G. Wagner's Fundamentals of Clinical Pharmacokinetics. A 1977 article compares the "classical" trapezoidal method to a number of methods that take into account the typical shape of the concentration plot, caused by first-order kinetics. [8]

  7. Assay - Wikipedia

    en.wikipedia.org/wiki/Assay

    An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.

  8. Reversed-phase chromatography - Wikipedia

    en.wikipedia.org/wiki/Reversed-phase_chromatography

    Silica gel particles are commonly used as a stationary phase in high-performance liquid chromatography (HPLC) for several reasons, [13] [14] including: High surface area: Silica gel particles have a high surface area, allowing direct interactions with solutes or after bonding of variety of ligands for versatile interactions with the sample molecules, leading to better separations.

    Summary of analytical methods for chiral analysis Method Brief narrative of principle and application; Chromatographic: Chiral HPLC Chiral HPLC is used to separate enantiomers either by direct or indirect separation mode. Widely employed to check enantiomeric purity, provided the reference standards of the racemate or the two enantiomers are ...
