This white paper describes the method of using Agilent Model 355 Sulfur Chemiluminescence Detector (SCD) to analyze sulfur compounds in citrus juices
This document provides a technical overview of using the Agilent Model 355 Sulfur Chemiluminescence Detector (SCD) to measure and analyze sulfur compounds in citrus juices, specifically grapefruit. It highlights the importance of detecting trace sulfur levels for flavor quality control.
The text describes an analytical approach involving gas chromatography with the SCD detector, utilizing s-methyl thiobutanoate as an internal standard. The document includes a discussion on how sulfur compound concentrations vary based on fruit maturity and season, illustrated by chromatograms.
The primary application is the analysis and speciation of sulfur compounds in citrus juices, such as grapefruit juice.
An internal standard of s-methyl thiobutanoate is added to juice samples prior to extraction.
The document states that the SCD is very useful due to its extreme sensitivity and selectivity for sulfur compounds.
