ASTM D7730-17

Standard Test Method for Determination of Dioctyl Sulfosuccinate in Sea Water by Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS)

SIGNIFICANCE AND USE
5.1 DOSS is an anionic detergent that is approved by the United States Food and Drug Administration (U.S. FDA) and is used widely as a laxative, emulsifying, solubilizing, and dispersing agent, and is used in the cosmetic industry.4 DOSS may also be used as a dispersing agent to treat oil. DOSS may be released into the environment at levels that may be harmful to aquatic life. The U.S. EPA aquatic life benchmark for DOSS is 40 ppb.5  
5.2 This test method has been investigated for use with reagent and sea water.
SCOPE
1.1 This test method covers the determination of dioctyl sulfosuccinate (DOSS) in sea water by direct injection using liquid chromatography (LC) and detection with tandem mass spectrometry (MS/MS). This analyte is qualitatively and quantitatively determined by this test method. This test method adheres to selected reaction monitoring (SRM) mass spectrometry.  
1.2 The detection verification level (DVL) and reporting range for DOSS are listed in Table 1.  
1.2.1 The DVL is required to be at a concentration at least 3 times below the reporting limit (RL) and have a signal/noise ratio greater than 3:1. Fig. 1 and Fig. 2 display the signal/noise ratio of the selected reaction monitoring (SRM) transition.  
FIG. 1 Detection Verification Level Signal/Noise Ratio  
FIG. 2 Reporting Level Signal/Noise Ratio  
1.2.2 The reporting limit is the concentration of the Level 1 calibration standard as shown in Table 5 for DOSS, taking into account the 50 % sample preparation dilution factor.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
