Ternary Gradient for Tenofovir Disoproxil Fumarate Impurity Profiling

Ternary Gradient for Tenofovir Disoproxil Fumarate Impurity Profiling

21 Jun 2015

This application note demonstrates how the simultaneous separation of early-eluting polar compounds and later-eluting nonpolar compounds is achieved by applying a ternary gradient with the Vanquish Flex UHPLC System2 using a Thermo Scientific™ Accucore™ aQ column. The impurities of the antiretroviral drug, tenofovir, are profiled using this method.

Thermo Scientific™ Vanquish™ Flex Quaternary UHPLC System

Thermo Fisher Scientific

The Thermo Scientific™ Vanquish™ Flex Binary UHPLC system is biocompatible with a state-of-the-art binary high-pressure pump and state-of-the-art binary solvent blending.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

Toxicology / Drugs of Abuse TestingToxicology and Drugs of Abuse Testing is the investigation into toxic and illegal substances found at the scene of a crime or from a suspect and / or victim associated with a scene of a crime. Analyzers, immunoassays and drugs of abuse test kits and presumptive test kits are an essential aspect of toxicology investigation.Drug TestingIt is essential to test the efficacy and toxicity of drugs at every stage of their development to ensure that a pharmaceutical product is fit for purpose and safe for use before reaching the stage of mass production and distribution.
