This research used gas chromatography/mass spectrometry (GC/MS) and electrospray ionization liquid chromatography/mass spectrometry (ESI-LC/MS) to analyze a commercially available fungicide formulation. GC/MS analysis provided a detailed look at the volatile components in the formulation, but did not yield any results for the active ingredient, triforine. ESI-LC/MS provided information on the stereoisomers of triforine as well as the nonvolatile surfactants and contaminants in the formulation. This paper demonstrates the complementary nature of these two analytical techniques when trying to fully characterize a complex chemical formulation containing a broad range of components.

This document introduces the use of Agilent ZORBAX 3.5 µm particles in HPLC rapid gradient separation of plant hormones.

This document presents examples of useful differences in band spacing that can be obtained by varying column type while keeping mobile phase conditions constant. The stationary phase strength (retentivity) is in the order C8>Phenyl>CN for these sterically protected bonded phases. Long-term stability and reproducibility are provided by ZORBAX StableBond columns. A wide range of herbicides can be separated with excellent peak efficiency and peak shape.

This document describes the use of a 3mm diameter ZORBAX Low-Volume Column for analysis of pesticides in drinking water. 28 pesticides are separated with good resolution and peak shape in a single run using simple mobile phases.

Using ZORBAX Eclipse XDB-C18 Rapid-Resolution (3.5µm) Cartridge-Column, can simultaneously reduce column length and particle size, thereby reducing analysis time, maintaining separation, and reducing solvent usage.

This document describes the separation performance of Agilent ZORBAX 300 SB-C8 for complex plant protein samples, and the effect of temperature in reverse phase separations of complex samples.

Aspartame is an artificial sweetener used as a sugar substitute in diet drinks and foodstuffs. This document introduces the analysis method of aspartame and its metabolites in food.

This document describes the method of separating vitamins D2 and D3 using the Agilent ZORBAX ODS column. The results show that the non-endcapped column has better retention and resolution than the endcapped column.

Agilent ZORBAX NH2 column has excellent resolution and retention in high performance carbohydrate analysis

The application note introduces Agilent ZORBAX Eclipse XDB-Phenyl column for flavor and food analysis, which has excellent separation ability and good peak shape.

This document introduces the method for analyzing various flavoring agents in food using Agilent ZORBAX SB-Phenyl, Narrow-Bore LC/MS column

This document introduces the application of Agilent 1100 quaternary pump equipped with ZORBAX Eclipse-XDB column in food analysis. The column has good chemical stability, and can be used for chromatography separation at intermediate pH values. By shortening the column length and particle size, the analysis time can be shortened, the separation can be maintained, and the solvent consumption can be reduced.

This document describes a high-speed HPLC method for separating parabens. The method uses a ZORBAX StableBond SB-C18 column and 0.1% H3PO4:ACN as the mobile phase. The run conditions are 2 mL/min flow rate, 1 µL injection volume, and 60℃ column temperature. The method can separate parabens in less than one minute.

This document describes a method for detecting EGCG in tea leaves. The method uses the Agilent ZORBAX SB-C8 column to separate a group of catechins in tea leaves under low pH conditions, and achieves good separation.

This document introduces the characteristics of ZORBAX 300SB-C8 and 300SB-CN two chromatographic columns from Agilent Technologies, which can achieve stable separation of high molecular weight, alkylated, wheat glutenin protein subunits.
