This LC-MS/MS kit is intended for the determination of Vitamin A & E in Serum / Plasma. The components in this kit must be used as stated in the user manual
Vitamin A & E are determined from human serum/plasma by Chromatographic separation coupled to a positive ion electrospray (ESI) LC-MS/MS. Before the LC-MS/MS analysis, a sample clean-up is performed to remove the sample matrix and to spike with the internal standard. After separation by chromatography on an analytical C-18 column, Vitamin A and Vitamin E are ionized by electrospray ionization (ESI) and detected by LC-MS/MS. Electrospray ionization is a soft ionization technique where a strong electric field is applied to the liquid passing through the ESI-capillary of the MS-source. The ions are mostly formed in solution before desorption and then transferred into the ion path of the tandem mass spectrometer, which consists of three quadrupoles (two mass selectors connected via a collision cell). Measurement of the analytes is carried out in MRM mode. In this mode, only selected ions (precursor ions) with a defined mass/charge (m/z) ratio are isolated in the first quadrupole and subsequently transferred into the collision cell, where they are fragmented by impact with an inert gas (argon or nitrogen) at defined voltage settings. Among the fragments generated (known as product ions), only those with a defined m/z ratio can pass the third quadrupole for final detection. In this way the MRM mode ensures a selective identification and quantification of the target analytes. A six-point lyophilized whole blood calibrator as well as lyophilized blood controls are also available for quality assurance. Both components are added to the “Starter Kit” (30261565), or can be ordered separately.
Two different concentrated solvent kits, as well as single components, are available to order.
This Kit includes everything necessary for a first installation of the Vitamin A and E LC-MS/MS kit on an LC-MS/MS system. Includes all solvents for HPLC and sample extraction, Calibrators, Controls, as well as one HPLC column and consumables.
The Solvent Kit includes a set of solvents to perform the sample extraction and the HPLC. Calibrators, Controls, Consumables, or an HPLC-Column are not included.
Furthermore, all components can be ordered separately.*
