Trace Sulfur Analyzers - Model 4025

The ability to reliably detect ultra-low-levels of light sulfur compound impurities in a variety of sample types is of vital importance to the oil and gas, environmental, and food and beverage industries, where product quality and compliance with regulations are paramount. 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 are met.

Overview

Model 4025 utilizes a sulfur chemiluminescence detector (SCD) for the analysis of sulfur in refinery gas, natural gas, process gas, Kraft gas samples, and beverage gases utilizing a heated gas sampling valve (GSV). Our SCD features an equimolar response to sulfur compounds, promoting a lack of carbon interference with a simple calibration. The analyzer can be designed as an online and/or multi-stream system, and also allows for the addition of a second or third channel, offering complete flexibility to meet the needs of your operation. Further customization options include the addition of a permeation-tube calibration chamber which mounts on the analyzer for easy access. A manual valve is used to select the calibration chamber or the sample input and the permeation tube chamber is capable of accommodating up to four permeation tubes or wafers for calibration of other non-sulfur compounds. Thee analyzer enables compliance with ASTM D5623, and offers detection limits of 10ppb for all sulfur compounds, including hydrogen sulfide (H2S), carbonyl sulfide (COS), sulfur dioxide (SO2) (cryogenic cooling required for COS/SO2 separation), mercaptans, aromatic sulfur compounds and sulfides.
