Automated Petroleum Fraction Separation Data for Ni and V Porphyrin Quantification

Daniel M. Silva created an automated method using open-source hardware for separating porphyrin fractions from crude oil. The method was applied to crude oils including a Venezuelan NIST 8505 sample and a sample from a marine reservoir. V and Ni concentrations were determined by ICP-MS, and V-porphyrin profiles were determined by HPLC-ICP-MS.

Use Cases

• Quantifying nickel and vanadium concentrations in petroleum fractions based on ICP-MS measurements.
• Profiling V-porphyrin compounds in crude oil samples based on HPLC-ICP-MS data.
• Developing automated liquid chromatography separation protocols based on absorbance signal derivatives.
• Comparing metalloporphyrin distributions between different crude oil types, such as biodegraded and non-biodegraded samples.

Strengths

• Method has good reproducibility as stated in the description.
• Includes specific concentration measurements, such as 4.9 mg L-1 V-porphyrins in Brazilian crude oil and 59 mg L-1 in the NIST 8505 sample.
• Provides percentage associations of metals with porphyrin classes, e.g., 18% of total V in one sample.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.

Collection Method

Data likely generated from automated preparative liquid chromatography with reverse phase gradient, absorbance signal measurement, and ICP-MS/HPLC-ICP-MS analysis.

Geography

Samples include a Venezuelan NIST 8505 crude oil and a crude oil from a marine reservoir, which may be Brazilian.
