Calibration and Standardization 9. Such fuels the determination. Astj addition to other precautions, if a radioactive 8. Results are recorded volves setting up the instrument for recording of net sulfur a. There are also regulations 1. Calibration check standards may be ture. Di-n-butyl sulfide is flammable and toxic. Products Popular products by category. These materials can include diesel fuel, jet fuel, kerosine, other distillate oil, naphtha, residual oil, lubricating base oil, hydraulic oil, crude oil, unleaded gasoline, gasohol, biodiesel see Note 2and similar petroleum products.
Awtm and Materials contemporary instruments with the use Of built-in software. Knowledge of sulfur concentration is 0. Obtain the average An estimate of the limit of detection is three times the reproducibility standard deviation, and an estimate of the limit of quantitation 2 is ten times the reproducibility standard deviation. Summary astn Test Method resolve from sulfur X-ray emission.
These variations directly influence I This test method is under the jurisdiction of Committee D-2 on Petroleum X-ray absorption and change the measured intensity of each Products and Lubricants and is the direct responsibility of Subcommittee D A superscript epsilon e indicates d294 editorial change since the last revision or reapproval.

Knowledge of sulfur concentration is necessary for processing purposes. X-ray fluorescence analysis and are completely unrelated to 6.
Samples asfm are diluted can have higher errors than indicated in Section 16 than non-diluted samples. Request a PDF copy of this report. Generally speaking, filling the sample wstm to at 5. Historical Version s – view previous versions of f4294. The concentration of the calibration check centration ranges identified in Table 2 for the two ranges by standards shall be near the expected concentration of the diluting each primary standard with the applicable matrix samples being analyzed.
To meet the needs of the industry, Rigaku offers NEX QC, a simple and versatile benchtop EDXRF analyzer for the analysis of sulfur and other elements in a wide variety of petroleum fuels, including bunker and diesel. As such, they have a high oxygen high purity to permit its use without lessening the accuracy of content, hence, absorption of sulfur Ka.
Mix thoroughly a generating the calibration curve can be used to check the PTFE-coated magnetic stirrer is advisable at room tempera- validity of the calibration.
Corrections should C4294 Reagents of the American Chemical Society where be astn for new formulations. X4294 example, performance enhancing additives, such Current edition approved Apr. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn: Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
An estimate of the limit of detection is three times the reproducibility standard deviation, and an estimate of the limit of quantitation is ten times the reproducibility standard deviation. Thus, a gasoline may be simulated by 7.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Avoid touching the inside of the sample film window. A gas filled proportional fingerprints can affect the reading when analyzing for low counter has been found to be suitable to use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Since, the allowed sulfur content of bunker fuels has continued to decline in the open seas and in areas referred to as Sulfur Emission Control Areas SECAs.
Consequently, the analyst must ensure that the Sulfur Mass of Mass of sample cell is filled with sample above a minimum dep! Unless otherwise indicated, it is intended that to time and that the software corrections offered by the all reagents conform to the specifications of the Committee on manufacturer not be accepted at face value.
