1.How to Facilitate Filtration of Small Volumes for HPLC and UHPLC Sample Prep-Pall Life Sciences

This application note provides guidance for obtaining the smallest hold-up volume possible when filtering small volume samples.

2.Intra-Laboratory Validation of an Alternative Column Chemistry-Sigma-Aldrich

Read this application note to compare traditional LC-MS/MS with a QuEChERS approach for the analysis of pesticides in fruits and vegetables.

3.Environmental Application Notebook: Quantitative MS-Waters

This application compendium demonstrates the suitability of Waters’ range of Xevo mass spectrometers for a number of Food and Environmental applications.

4.Analysis of Sugars in Orange Juice and Grape Juice by Prominence-i and Differential Refractive Index Detector-Shimadzu

Discover how sugar is analyzed in juices using the Prominence-i integrated high-performance liquid chromatography with the RID-10A differential refractive index detector. A ligand exchange column is utilized, enabling high temperature capabilities.

5.Determination of Benzo(a)pyrene in Sausage and Preserved Ham-Thermo Fisher Scientific

This application note provides a sensitive and rapid HPLC method with online SPE and fluorescence detection for the determination of benzo(a)pyrene in sausage and preserved ham.

6.Enhancing the Flexibility of the NGC™ Chromatography System: Addition of a Refractive Index Detector for Wine Sample Analysis -Bio-rad

Learn how a chromatographic workflow is used for the quantitation of wine constituents using a Bio-Rad NGC Chromatography System equipped with an Aminex® HPX-87H HPLC Column. Results demonstrate the ability of the NGC System to effectively integrate an external refractive index (RI) detector, in addition to the standard multi-wavelength UV detector that comes with the system.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.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.Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses. Find the best IR spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats. Find the best SPE, SLE and SPME equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.QuEChERSThe QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) method is a streamlined approach that is used to extract multi-residue target compounds from food samples. It is most commonly used by analytical chemists studying pesticide residues in food.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.
