Liquid Chromatography Mass Spectrometry (LC/MS) No matter what your application or matrices, our liquid chromatography and mass spectrometry (LC/MS) systems deliver the speed, sensitivity, exact mass information, wide dynamic range, and mass accuracy you need for having complete confidence in your results.

agents, clarifying agents, preservatives, PAHs, slip agents •LC-UV-MS – non-volatile organic compounds, large oligomers, large antioxidants, thermally labile compounds •Ion chromatography – Bromide, chloride, fluoride in elastomers •ICP-MS – metals from aluminum canister, glass •Chemiluminescence Detection – nitrosamines

The LC-MS/MS system used for determination and quantification of the analytes was a Vanquish ultra-high pressure liquid chromatograph (UHPLC, Thermo Fisher, San Jose, CA) coupled to a high-performance, ion funnel TSQ Altis ™ Triple Quadrupole Mass Spectrometer (Thermo Fisher, San Jose, CA). Analytes were separated with an Acclaim® Mixed-Mode

Oct 16, 2020 · Liquid chromatography–mass spectrometry (LC–MS) is the analytical platform that provides the widest metabolome coverage in untargeted studies . Several tools are broadly used in the metabolomics community for preprocessing LC–MS data, such as MZmine2, XCMS, MSDIAL, and workflow4metabolomics [8,12,13,14], among others. These software

Dec 10, 2020 · Wide-spectrum amino acid determination using aTRAQ kit and LC-QqQ-MS/MS. In the first step, a pilot study aimed at the optimization of HBV sample treatment was conducted using a pooled venom sample.

Each vial/closure combination lot has been tested by LC-MS and GC-MS on traces of blank values and contaminations.Vials are available in all capacities, materials like plastic vials or glass vials, and in a variety of colors to meet any collection, storage, or analysis need. Tailor vessels for specific media with various translucent manufacturing and different sterility options for precise

Jun 01, 2017 · Risperidone (RIS) is used as an antipsychotic drug alone or with other drugs, like fluoxetine (FLX). A simple method was developed and validated for the determination of both RIS and its metabolite 9-hydroxyrisperidone (9-OH-RIS), FLX, and olanzapine (OLA) as an internal standard in rat’s plasma using UPLC-MS/MS. FLX, RIS, 9-OH-RIS, and OLA were purified using acetonitrile as a protein

The SQ Detector 2 is an advanced benchtop single quadrupole mass detector designed for high performance LC-MS applications. With a wide range of ionization options including APPI and ASAP, the SQ Detector is ideally suited to qual/quan applications.

Nov 01, 2013 · LC-MS is increasingly used for therapeutic drug monitoring of tacrolimus. A recent summary from an international proficiency-testing scheme demonstrated that the mass spectrometry respondents were the largest method group. However, these methods lack standardization, which may explain the relatively poor interlaboratory agreement for such methods.

Formic Acid LC-MS-grade formic acid is recommended, Fisher p/n A117 or equivalent. 18.2 M Ω Water For glycan sample prep. LC-MS-grade water is critical for glycan analysis, Fisher p/n W6 or equivalent. Acetonitrile LC-MS-grade acetonitrile is highly recommended for mass spectrometry analysis of glycans, Fisher p/n A955 or equivalent.

Sep 01, 2013 · Christine Bobin-Dubigeon, Marie Amiand, Christelle Percheron, Christelle Audeval, Sophie Rochard, Pierre Leynia, Jean-Marie Bard, A New, Validated Wipe-Sampling Procedure Coupled to LC–MS Analysis for the Simultaneous Determination of 5-Fluorouracil, Doxorubicin and Cyclophosphamide in Surface Contamination, Journal of Analytical Toxicology, Volume 37, Issue 7, September 2013, Pages 433

Thomson Filter Vials are manufactured without the use of plasticizers or mold release agents, making them LC/MS clean. Testing with ELSD, PDA, and MS detection by Takeda Pharmaceutical showed no leaching from Thomson Standard Filter Vial with a 0.45um, PTFE membrane compared to significant leaching from Millipore Millex-FH® Filter, 0.45M

A carrier protein is a more LC-MS friendly blocking agent, but it is not without any shortcomings. It adds unwanted complexity back into samples. This may complicate the LC-MS baseline of full scan or untargeted methods while it may indirectly affect targeted SRM (selected reaction monitoring) methods through ion suppression.

Open Value non-company-wide is a transactional agreement for commercial and government organizations. Software Assurance is included. Open Value company-wide and Open Value Subscription are commitment-based agreements for commercial and government organizations that want to license organization-wide over a one or two-year period.
