Guide to achieving reliable quantitative LC-MS measurements

Quantitative LC-MS Guide, 1st Ed. 2013 Page i Preface Mass spectrometry (MS) has the capability to separate organic molecules according to their molecular mass and permits their detection and quantitation with extremely high sensitivity. High performance liquid chromatography (HPLC) facilitates the rapid, quantitative

Dilute-and-shoot triple parallel mass spectrometry method for

reversed-phase (RP) HPLC step to separate vitamin D 2 and vitamin D 3 for quantification. These methods are lengthy, labor intensive and require large amounts of resources (chemicals, extraction solvents, chromatography solvents, two dedicated liquid chromatographs, etc.). We have developed a new method for analysis of dietary

MS Certified and Certified Vial Kits | Thermo Fisher

The vials contain virtually close to no particles any longer, which might contaminate and block your systems Closure contains ultra-low-bleed silicone septa for ultra trace analysis Products are shrink wrapped in order to assure originality, purity and transport safety.

High-performance liquid chromatography-mass spectrometry in

The development of HPLC-atmospheric pressure ionization-mass spectrometry (HPLC-MS) has presented clinical laboratories with a powerful analytic tool. The aim of this paper is to provide an overview of the current status of HPLC-MS in the clinical laboratory; to discuss the challenges to mass spectrometry in this setting; and to present some of

Glass vials or plastic vials for liquid samples containing

I've heard that proteins/peptides especially when below 100 ppm may attach to the internal glass surface of a vial and so no analyte of interest will enter the (nano)LC-MS system during injection.
