DVLS Sulfur Impurities in Gas Analyzer

Da Vinci Laboratory Solutions offers a Sulfur Components Analyzer based on an PFPD detector to determine sulfur compounds in gases according to ISO 19739. The analyzer determines individual volatile sulfur-containing compounds in gaseous fuels by gas chromatography (GC) using a pulsed flame photometric detector (PFPD).

GC-PFPD Analysis of Sulfur Impurities in Natural Gas

The liquefied gas sample is kept under constant pressure by means of the Pressure Station. After vaporising the sample with a heated vaporizer, a gas sampling valve is filled. To ensure a stable (atmospheric) pressure inside the loop, after the GSV loop is sufficiently flushed, the flow is manually stopped using the pressure station. Next the GC method and data acquisition are started by pressing the start button on the manual interface. The GSV is switched in flow with the total flow line, transporting the volume of the loop to the split inlet. In the inlet, the sample is transferred onto an analytical column. The column separates compounds based on their boiling points. After eluting from the column sulfur containing compounds are detected by the PFPD detector.
