Empirical Formula Determinations and Compound-Independent Calibration Using a GC-AED System

This document introduces a protein separation method based on high-performance liquid chromatography. The method uses non-covalent affinity chromatography columns and polyacrylamide gel chromatography columns, which can effectively separate proteins of different molecular weights.

This document introduces Agilent's J&W low bleed columns, including product features, characteristics and advantages.

Agilent low bleed GC/MS columns are specifically designed to overcome the challenges of low level trace analysis. These columns have low bleed and high temperature performance, providing more accurate results without compromising analysis time.

This paper introduces the method of using UV-Vis spectroscopy to screen environmental samples.

This document introduces a single-column technique for analyzing carbon, sulfur, and nitrogen compounds in a gaseous matrix. The analysis is performed with an Agilent 6890 gas chromatograph (GC) and an Agilent G2350A atomic emission detector (AED). An Agilent 30 m × 0.53 mm × 5 µm J&W DB-1 capillary column is used for separation.

This Application Note describes the separation and identification of phytoestrogens in red clover using UV-visible and fluorescence detection.

This document describes a method for determining naproxen levels in serum using a Zorbax SPE C18 cartridge. The method uses solid phase extraction to significantly reduce the levels of interfering substances. The target analyte is then quantified by reversed-phase HPLC.

This document describes a method for extracting quinine from serum using a Zorbax SPE C18 column. The method is illustrated with a flow chart, a list of reagents, a sample preparation method, chromatographic conditions, and sample results.

The document describes a solid phase extraction method for a pharmaceutical compound called Ranitidine. This compound is used for the treatment and prevention of ulcers and for the relief of heartburn. By using a Zorbax SPE C18 cartridge, levels of interfering substances in the bloodstream can be significantly reduced, allowing for easy quantitation of the analyte of interest using reversed-phase HPLC.

The document describes the significant reduction of matrix compounds in plasma by using a Zorbax SPE C18 cartridge, facilitating the quantification of testosterone-like compounds by reversed-phase HPLC. The document also provides methods for solid phase extraction and sample preparation.
