This application note demonstrates a comprehensive comparison of different liquid chromatography approaches for the separation of 300 endogenous metabolites. RPLC, HILIC, and mixed-mode LC were performed for the metabolite standards.

Thermo Scientific™ Acclaim™ Trinity P1 LC Column

Thermo Fisher Scientific

Acclaim™ Trinity P1 is a unique, high-efficiency, silica-based column designed for pharmaceutical applications such as simultaneous separation of pharmaceutical drug substances and their counterions. his new column, based on nanopolymer silica hybrid (NSH) technology, provides multiple retention mechanisms including reversed-phase, anion-exchange, and cation-exchange. As a result, its selectivity can be easily optimized by adjusting mobile phase buffer concentration, pH, and solvent content concurrently or independently.The NSH technology ensures distinctive spatial separation of the anion-exchange and cation-exchange regions, which results in maximum flexibility in method development. The easy-to-optimize selectivity can be used to accelerate chromatographic separations and increase productivity.Acclaim Trinity P1 LC Column Features: Multiple retention mechanisms including reversed-phase, anion-exchange, and cation-exchange Adjustable selectivity by mobile phase ionic strength, electrolyte type, pH and organic solvent Ideal selectivity for simultaneous separation of basic, neutral, and acidic analytes Separation of hydrophilic ionic and ionizable analytes without ion-pairing reagents Applications: Active Pharmaceutical Ingredients (API) and counterions (cations or anions). Screening of pharmaceutical counterions. Both UV and an ELS detector, in series, are required for simultaneous determination of both drug substances and counterions. Mixture of acidic and basic drug substances and respective counterions. Drug substances: of acidic, basic and neutral mixtures. High throughput analysis following optimization of the selectivity and resolution. The flow rate can then be increased, and the analysis time shortened. Column Details: Chemistry: SCX, WAX and RP Mixed-Mode Length: 50, 100, 150 mm ID: 2.1, 3.0 mm

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS 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.
