Welcome to the LGC catalogue of petroleum Certifed Reference Materials (CRMs) The frst section of the catalogue details the extensive VHG Labs line of analytical reference standards for both new and used oil applications. Our petroleum standards may be used for analysis by ICP, ICP-MS, AA, XRF, RDE, UVF, physical testing instruments and other used oil analysis instruments. We have been manufacturing single and multi-element standards (both sulfonate-based and sulfur-free versions) for more than 30 years. We manufacture an equally extensive line of single and multi-element inorganic aqueous standards. The second section of this catalogue gives an overview of other CRMs which LGC offers. Most norms expect to complete development of an application (calibration) by analyzing a CRM as an unknown sample to validate or verify the analytical procedure. We can offer some standards with full analysis, including C, H and N, especially for XRF and its fundamental parameter mathematics. Our commitment to quality VHG brand petroleum standards are subjected to rigorous Quality Assurance checks prior to shipment. Raw materials are assayed and analyzed for trace impurities. Major constituents are generally verifed both instrumentally, against the appropriate NIST SRM (when available), and through classical wet chemical methods (titrimetry or gravimetry). Our standards are blended in pre-cleaned HDPE or glass reactors. Balances and volumetric flasks are calibrated according to NIST procedures. All VHG standards are accompanied by a comprehensive Certifcate of Analysis (COA). Each COA is supported by an unbroken chain of comparisons with traceability to national or international standards of measurement. Our manufacturing facility is registered to ISO 9001 and accredited to ISO Guide 34. Each product must pass rigorous Quality Control in our ISO/IEC 17025 laboratory and is shipped with a comprehensive Certifcate of Analysis (COA) with actual (not nominal) concentrations. Our profciency testing program for oil analysis is ISO/IEC 17043 accredited. Thank you to all of our customers. We look forward to supporting your continued success. The LGC team

VHG Tips Section 1 Petroleum The use of stabilizer is particularly important for long-term stability when diluting these standards in solvents. V-Solv ICP Solvent V-Solv ICP Solvent is a proprietary solvent that is used for diluting oil and other organic liquids for analysis by ICP and ICP-MS. Use V-Solv as a matrix blank and as a diluent for your calibration standards and samples for outstanding nebulization characteristics. V-Solv ICP Solvent offers the following advantages over conventional low odor/odorless kerosene, xylene and other commercial solvents: u Very high purity (essentially no trace metals or sulfur) - each bottle is accompanied by a COA that states the trace impurity levels of 36 metals and sulfur. u Makes very stable dilutions of metallo-organic standards and oil samples. u Extremely low odor (no kerosene or aromatic smell), which results in a comfortable work environment and is also VOC-exempt for consumer products applications (EPA Title 40, Volume 5, Parts 53-59). u Extremely low toxicity compared with kerosene or xylene. u Very competitively priced and non-hazardous to ship (flashpoint of 260 F). u One gallon bottle size for ease of use and for shipment via common carrier.

VHG Tips Section 1 Petroleum Many commercial metallo-organic standards have matrices of sulfur-containing compounds. Use VHG s unique sulfur-free standards if the absence of S is important for your application. Alternatively, known amounts of S can be blended intentionally. For multi-element XRF analysis, the element concentrations should be spread randomly across the suite of standards in order to best correct for inter-element effects. Metallo-Organic Concentrates Sulfur-Free Matrix: Excellent for XRF Metallo-Organic Concentrates - Single Element These sulfur-free, metallo-organic concentrates are ideal for X-ray fluorescence (XRF). They can be used to prepare single or multi-element standards, individually or as a set. Sulfur can be added for the simultaneous analysis of sulfur and metals. Each product is accompanied by a Certificate of Analysis that documents the assayed concentration and any trace impurities. Element Nominal Conc.

Biodiesel As the demand for biofuels continues to rise, the need to reliably analyze these products has become a necessity for the petroleum industry. Most biodiesel fuels are comprised of a blend of traditional refined diesel combined with biodiesel fuel. The percentage of biodiesel in the blend is generally 5%, 10% or 15%, and is labeled B5, B10, or B15 respectively. Pure biodiesel (100%) is labeled B100. All of our diesel standards have a matrix of 100% biodiesel. This is important in the analysis of materials by ICP and other methods because the analysis can often be encumbered by the variance of matrices from standards to samples. Our biodiesel standards have been formulated specifically for the analysis of metals and sulfur in biodiesel fuel. Our B100 is made from soybean oil and is an excellent matrix match for almost all biodiesel fuel analysis. Metals in Biodiesel These standards have been formulated specifically for the analysis of metals in biodiesel fuel in accordance with ASTM D6751, EN 14107, EN 14108, EN 14109, EN 14214, or EN 14538.
