One such method to besides these films may be used for X-ray windows, provided accomplish the removal of water is to centrifuge the sample first under that they do not contain any elemental impurities. Generally speaking, filling the sample cup to at 5.

Non-destructively analyze from sodium Na through uranium U in almost any matrix, from solids and alloys to powders, liquids and slurries. Use the certified sulfur the sample. Hence, the matrix diluent should be as close to the which are certified by a national standards organization, may form of the matrix being analyzed as possible.

Note 1—Oxygenated fuels with ethanol or methanol contents exceeding the limits given in Table 1 can be dealt with using this test method, but the precision and bias statements do not apply see Appendix X3.

However, Samples should be analyzed immediately after pouring into a attention to the source is only to be carried out by a fully trained and competent person using the correct shielding techniques.

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by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn: Oil from resolution value not to exceed eV.

Two groups of calibration sured concentration of sulfur, or more than a few hundred samples are required to span the concentration range 0. 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 d429 Subcommittee D There are also regulations promulgated in federal, state, and local agencies that restrict the amount of sulfur present in some fuels.

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.

Remember me on this computer. A typical analysis time is 2 to 4 min per gasoline all unleadedand other distillates. NEX QC is an important tool to meet the requirements for monitoring sulfur at these various levels, with the ability to measure sulfur over a broad range of concentrations and into the future as sulfur levels become even lower. Films found to be suitable are polyester, NOTE I-In the case of petroleum materials that contain suspended polypropylene, polycarbonate, and polyimide films.

Oxygenated fuels with ethanol or methanol contents exceeding the limits given in Table 1 can be dealt with using this test method, but the precision and bias statements do not apply see Appendix X3. Rigaku nano3DX is a true X-ray microscope XRM with ultra-wide field of view, 25X larger volume than comparable systems, and three X-ray wavelengths for different matrices.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. It is recom- analyzed four times.

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 d4924 of petroleum fuels, including bunker and diesel.
