In analytical chemistry, cross-validation is an approach by which the sets of scientific data generated using two or more methods are critically assessed. [1] The cross-validation can be categorized as either method validation [ 1 ] or analytical data validation.
HPLC has many applications in both laboratory and clinical science. It is a common technique used in pharmaceutical development, as it is a dependable way to obtain and ensure product purity. [59] While HPLC can produce extremely high quality (pure) products, it is not always the primary method used in the production of bulk drug materials. [60]
Validation and Quality Control: It is important to ensure the accuracy and reliability of the integration process, by performing validation and quality control checks to the software itself. This may involve comparing integration results with known standards, replicating analyses, and assessing precision and accuracy [ 6 ]
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
Validation or verification is generally needed when a health facility acquires a new device to perform medical tests. The main difference between the two is that validation is focused on ensuring that the device meets the needs and requirements of its intended users and the intended use environment, whereas verification is focused on ensuring ...
Phenyx incorporates OLAV, a family of statistical scoring models, to generate and optimize scoring schemes that can be tailored for all kinds of instruments, instrumental set-ups and general sample treatments. [15] ProbID Open source: ProbID is a software tool designed to identify peptides from tandem mass spectra using a protein sequence database.
Mass spectrometry is a scientific technique for measuring the mass-to-charge ratio of ions. It is often coupled to chromatographic techniques such as gas-or liquid chromatography and has found widespread adoption in the fields of analytical chemistry and biochemistry where it can be used to identify and characterize small molecules and proteins ().
The spot capacity (analogous to peak capacity in HPLC) can be increased by developing the plate with two different solvents, using two-dimensional chromatography. [8] The procedure begins with development of a sample loaded plate with first solvent. After removing it, the plate is rotated 90° and developed with a second solvent.
