We work with leading manufacturers to produce a wide range of Petroleum, Lube, Crude Oil and Polymer Calibration Standards. UcalibrateIT http://www.ucalibrateit.com Page 1 of 67

Our Focus is Quality to Meet Your Standards UcalibrateIT provides Instrument Calibration Standards to Refinery Plants, Chemical Plants, Regulatory Authorities and Private Labs. We partner with the Top US Manufacturers specializing in manufacturing multi-element standards in difficult matrices. All of of our Standards have been formulated to meet the requirements of both ASTM and EPA Methods. All raw materials are checked for chemical purity and the prepared standards analyzed for composition. The results are then compared against the gravimetric figures and are NIST traceable by weight. The Standards are designed specifically for the Analytical Chemist to efficiently and economically analyze for the required properties. We provide instrument calibration standards for the Petroleum, Lubricants, and Polymer industries. The advantages of using UcalibrateIT Standards are: Increased confidence in analytical results by using Method Specific Calibration Standards; Minimum time spent preparing calibration curves, enabling greater productivity by laboratory staff; All Standards are ready to use and available with or without an Internal Standard; Standards are made in large quantities and packaged in glass ampoules, thus ensuring uniform composition and continuity of supply of Standards with the same composition; Daily Calibration Checks and Reference Standards are available, conforming to ASTM Methods; Large quantities are available for the calibration of Process Analyzers. www.ucalibrateit.com Page 2 of 67

GASOLINE REFERENCE STANDARDS In early 1996 we conducted an Inter-Laboratory study on a California Phase II Gasoline. The object of the study was to provide a well analyzed standard for checking calibrations and for use in SQC Programs. A total of 25 refinery laboratories participated and the results were statistically analyzed and the mean reported. The Gasoline is packaged in 25 ml glass ampoules under an argon atmosphere.
