ASTM D6667 Total Volatile Sulfur in Gaseous Hydrocarbons/Liquefied Petroleum Gases
ASTM D6667 Standard Test Method for Determination of Total Volatile Sulfur in Gaseous Hydrocarbons and Liquefied Petroleum Gases by Ultraviolet Fluorescence
1. Scope
1.1 This test method covers the determination of total volatile sulfur in gaseous hydrocarbons and liquefied petroleum (LP) gases. It is applicable to analysis of natural, processed, and final product materials containing sulfur in the range of 1 to 100 mg/kg (Note 1).
NOTE 1 - An estimate of pooled limit of quantification (PLOQ), information regarding sample stability and other general information derived from the inter-laboratory study on precision can be referenced in the ASTM research report.
1.2 This test method may not detect sulfur compounds that do not vaporize under the conditions of the test.
1.3 This test method is applicable for total volatile sulfur determination in LP gases containing less than 0.35 % (mass/mass) halogen(s).
1.4 The values stated in SI units are to be regarded as standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. See 3.1 and Sections 6 and 7 for specific warning statements.
