Introducing the DVLS Liquefied Gas Injector – a swift, secure, and highly accurate solution designed for Sampling & Analysis of impurities within Liquefied Gases. This technique adheres to the standardized ASTM D7756 and EN 16423 methods, ensuring residue analysis precision in LPG.

The DVLS Liquefied Gas Injector is your laboratory’s reliable and efficient GC standard, catering to diverse applications:

• Assessment of oily residues and light contaminants in LPG (ASTM D7756, EN 16423)
• Detection of amines in LPG
• Identification of Benzene and Toluene in LPG (ASTM D7756)
• Elemental sulfur evaluation in LPG
• Analysis of nitrogen, carbon dioxide, hydrogen sulfide, and hydrocarbons in (un)stabilized gas condensate
• Composition & impurities analysis in substances like butadiene, crude C4 & raffinate (ASTM D2593, D4424, D2426)
• Traces of oxygenates in liquid hydrocarbon matrices (ASTM D7423, D7754)
• Hydrocarbon composition assessment in LPG (ASTM D 2163, ISO 7941)

Benefits:

• Safe liquefied gas injection: LGI’s direct injection method eliminates the need to evaporate large liquefied gas volumes.
• High repeatability: Direct liquid injection ensures excellent consistency and avoids discrimination of high boiling components.
• Proven technology: Trusted by global leading oil refineries since 2010.
• Broad application range: Ideal for analyzing heavy components in light matrices like LPG.
• Precise performance: Demonstrates exceptional accuracy with detection limits as low as <0.1 mg/kg for individual impurities.
• Standardized excellence: The LGI, a Da Vinci innovation, is standardized as ASTM D7756 and EN 16423 for gas chromatography-based analysis of oily residue in liquefied petroleum gases.
