Examination of Analysis of the Total Sulfur Content Using Nexis™SCD-2030

User Benefits

- Nexis SCD-2030 can easily quantify the total sulfur content in a sample without column separation. - It can quantify the total sulfur content in a sample using a calibration curve created from a sulfur compound which concentration is already known. - It can be applied to monitoring the level of sulfur compounds in a sample.

Introduction

The Sulfur Chemiluminescence Detector (SCD) is a selective and highly sensitive GC detector for sulfur compounds, and has the following characteristics: • No peaks will be detected in principle when samples with no sulfur compound content are introduced into the SCD • The SCD responds linearly in proportion to the number of sulfur atoms (S atoms) introduced into the detector. Thus, it displays the same sensitivity (i.e. equimolar sensitivity) regardless of compound species provided the same number of S atoms (i.e. S mol number) is introduced. These characteristics suggest that the total sulfur content can be quantified more easily by omitting column separation step when a sample is introduced into the SCD. This article examined the feasibility of the quantification of the total sulfur content in a sample using the SCD by comparing the results of the analysis with and without column separation.
