Spectroscopic and Chromatographic Equipment for Petroleum

Petroleum analytical instruments for composition, elemental, and molecular analysis | ASTM, ISO & EN

Petroleum analytical instruments for spectroscopy and chromatography fall into two complementary technology families used to determine the elemental composition, molecular structure, and chemical species content of petroleum products, fuels, lubricants, and related materials. Torontech supplies these instruments to refineries, commercial oil laboratories, petrochemical plants, power utilities, and QC teams across North America and worldwide.

Gas chromatography separates and quantifies individual molecular compounds in complex petroleum matrices, while spectroscopy techniques (ICP-OES, RDE-OES, AAS, and UV-VIS) detect and measure trace elements, wear metals, and additive concentrations from percent levels down to sub-ppm. Together they cover the full analytical scope that petroleum laboratories require.

How to Choose the Right Petroleum Analytical Instrument

• To identify what molecular or chemical species are in a fuel, gas, or lubricant: choose a GC system — gas chromatography resolves individual compounds that viscosity, density, and flash point tests cannot distinguish. Match the GC to your specific matrix (gasoline, LPG, natural gas, biodiesel, transformer oil, or used engine oil).
• For dissolved gas analysis in transformer insulating oil: choose the TOGA GC (ASTM D3612, IEC 60567), which is pre-configured for head-space gas extraction and dual-detector (TCD and FID) measurement of all fault gases simultaneously.
• To quantify additive or contaminant elements in a lubricant by ICP: select the system matched to your matrix — unused lube (ASTM D4951) for new oil formulation and used lube (ASTM D5185) for in-service oil, since each requires matrix-specific calibration curves and digestion conditions.
• For high-throughput used oil wear metal screening without sample preparation: choose RDE-OES (ASTM D6595, D6728), which delivers 24 to 32 element results in approximately 30 seconds directly from the oil sample with no digestion or dilution.
• For trace metal analysis in crude oil or heavy residual fuels: choose the ICP configured for ASTM D5708, which handles the high-viscosity and high-matrix conditions specific to crude and residual products.
• For lead in gasoline or regulatory leaded fuel monitoring: choose AAS per ASTM D3237, the standard reference method for lead determination accepted by regulatory programs worldwide.
• For naphthalene content in aviation turbine fuel, or UV absorption characterization of petroleum aromatic content: choose UV-VIS spectrometry per ASTM D1840.
