14 May 2019 HILIC-CAD analysis of commercially purchased hyaluronic acid products indicated that samples were composed of GlcNAc and GlcA.

19 Jan 2015 The chromatographic simulation of reversed-phase separations has chromatography (SFC) are becoming more popular for the analysis of  The Charged Aerosol Detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer. Liquid chromatography with charged aerosol detection (LC-CAD) analysis is a powerful technique used for polysorbate quantification and profiling. After a separation step via high-performance liquid chromatography (HPLC), the column eluent is nebulized by a nitrogen flow, the mobile phase is evaporated together with other volatile components. Charged aerosol detection (CAD) technology delivers performance that refractive index (RI), low wavelength UV, and evaporative light scattering (ELS) detectors simply cannot match. A charged aerosol detector helps you see analytes that other technologies fail to detect. Analysis for Polysorbate 80 Using New HPLC-CAD Method. Polysorbate 80 (polyoxyethylene (20) sorbitan monooleate) is a common nonionic surfactant, emulsifier and solubilizer that is used in a wide variety of industries and applications. A well-developed analytical method is crucial for accurately quantitating polysorbates. The ELSD can work with gradients and switch methods, the CAD just about copes with very gentle gradients but can't handle switches as the baseline takes too long to settle. Given the cost as well of the detectors (8k for used ELSD vs. 25k for used CAD!) if you can use either I'd definately stick with the ELSD given my experiences! Ion Chromatography (IC) with conductivity detection Ultra-High Performance Liquid Chromatography (UHPLC) with Charged Aerosol Detection (CAD) and/or UV detection Both IC and UHPLC are capable of drug salt, or counter ion detection, but the choice of technique can depend on the type of analysis, the information required and sample throughput.

The Charged Aerosol Detector (CAD) is a detector used in conjunction with high- performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography It is commonly used for the analysis of compounds that cannot be detected using traditional UV/Vis approaches due to their lack of a  14 May 2019 HILIC-CAD analysis of commercially purchased hyaluronic acid products indicated that samples were composed of GlcNAc and GlcA. Charged aerosol detection (CAD) technology delivers performance that refractive is the best choice for near universal detection for true quantitative analysis. 15 May 2019 HILIC-CAD has emerged as an effective platform for direct monosaccharide composition analysis of complex carbohydrates without derivatization  diesel by normal-phase LC, phytosterols in natural oils, and fat soluble vitamins found in commercially available supplements. Analysis of Lipids by HPLC-CAD. 1 Apr 2009 Over the past several years, charged aerosol detection (CAD) has become a widely used technology in the pharmaceutical laboratory.

Application of HPLC-CAD as a QC platform. The monosaccharide composition of commercially purchased HA products were analyzed to demonstrate the application of the HILIC-CAD method. Samples (> 5 mg) were hydrolyzed using 2 mL of 2 M trifluoroacetic acid (TFA) at 110 °C for 2 h prior to composition analysis.

The Figure 1 in the following link shows that CAD gives significantly higher sensitivity than Sedex 85 for Na and Cl ions under the same chromatographic conditions. If you are interested in reading the rest content in the same file, you will see Acclaim Trinity P1 with CAD is a useful combination for pharmaceutical API and counterion analysis. The ELSD can work with gradients and switch methods, the CAD just about copes with very gentle gradients but can't handle switches as the baseline takes too long to settle. Given the cost as well of the detectors (8k for used ELSD vs. 25k for used CAD!) if you can use either I'd definately stick with the ELSD given my experiences! Download CHROMuLAN - Open Chromatography Station for free. SW for controlling of chromatographic devices and subsequent evaluation of the acquired data. Integrated instrument control uses uLAN protocol. Simultaneous analysis of an Active Pharmaceutical Ingredient (API) and its counter ion. This application is best achieved using either a HILIC or a mixed-mode column (for example the Thermo Scientific Acclaim Trinity column) on a HPLC/UHPLC system. Isocratic and Gradient Capable: Unlike RID or EC, CAD/ELSD allows the use of gradients and the use of UV obscuring solvents. Because the mobile phase is evaporated away, little to no baseline drift occurs during gradient analysis (often improving integration results). chromatography (HPLC) is the preferred and most commonly used approach for surfactant analysis, it is always challenging to choose suit-able methods for specific applications. For example, the existing HPLC methods do not provide optimal separation for anionic, nonionic, cationic, and amphoteric surfactants in a single analysis.

HILIC-CAD was further investigated by flow injection analysis (FIA) using 29 and purification of polar compounds by high performance liquid chromatography.
