Sulfur chemiluminescence detection (SCD) is known as an excellent device for sulfur compound analysis because its response is inherently linear, equimolar, and far less susceptible to hydrocarbon interference. For example, ASTM Method D5623-94 uses SCD for the detection of sulfur compounds in gasoline.

1995年1月1日 · This chapter discusses a sulfur chemiluminescence detector (SCD). Many analytic techniques have been developed for the measurement of the sulfur content of petroleum and petroleum products.

1993年9月1日 · Laser fluorination of powdered samples, previously analyzed by conventional bulk SO 2 or BrF 5 methods, verifies that comparable precision and accuracy can be achieved with the new method. The δ34SCDT and δ33SCDT values of powdered samples are independent of F 2 gas pressure over a range of from 15 to 120 torr.

In a sulfur chemiluminescence detector (SCD), samples (sulfur compounds) eluted from a GC column are injected into a burner to cause oxidation and reduction reactions. Then the samples (SO radicals) are sent to a reaction cell, where they collide with ozone, which generates light emission that is detected by a photomultiplier.

PerkinElmer’s portfolio of trace sulfur analyzers utilize gas chromatography techniques with a sulfur chemiluminescence detector (SCD) to detect sulfur at part per billion levels. A programmable pneumatic control is utilized on our trace sulfur analyzers to use precise and automated gas flow, ensuring your quality and productivity objectives ...

Sulfur chemiluminescence detection using SCD-2030 enables selective detection of sulfur compounds in high matrix load petrochemical samples down to low concentration levels.
