what is total hydrocarbons test used for

Summary

Total hydrocarbons tests are used to measure the amount of hydrocarbons found in a sample of soil, water, or air. 1 The amount of total petroleum hydrocarbons (TPH) found in a sample is used as a general indicator of petroleum contamination at that site. 1 Total Recoverable Petroleum Hydrocarbons (TRPH) or Total Petroleum Hydrocarbons (TPH) are hydrocarbons that exist in crude oil, which is used to make petroleum products. 2 The only method approved for testing oil and grease in wastewater is EPA Method 1664A. 3 EPA Method 418.1 is also used to measure n-hexane or other components with a boiling range near or below the boiling point of n-hexane. 3

Summary Withdrawal of Approved Methods Employing CFC-113: Methods that employ CFC-113 as the extraction solvent and that were approved for testing of oil and grease in water at 40 CFR Part 136 are EPA Method 413.1 and Standard Methods No. 5520B. EPA withdrew these methods in the final rule published March 12, 2007. The only method approved for testing oil and grease in wastewater is EPA Method 1664A. Meth... Recommended Method For Testing Oil and Grease and Total Petroleum Hydrocarbons: Method 418.1: Total petroleum hydrocarbons (TPH) are not Part 136 pollutants. However, there may be samples for which Method 1664 may not be suitable; e.g., when it is desirable to measure n-hexane or other components with a boiling range near or below the boiling point of n-hexane. In those situations, analysts in the past may have used EPA Method 418.1 (“Petro... Source For N-Hexane For Use with EPA Method 1664A: Method 1664A requires use of n-hexane as the extraction solvent. The specification for the n-hexane to be used is "85% minimum purity, 99.0% min. saturated C6 isomers, residue less than 1 mg/L." In 2004, EPA received notice from Conoco Phillips that, effective November 1, 2004; Conoco Phillips would discontinue n-hexane production at its Borger, Te... Use of Repetitive Amounts of Silica Gel with EPA Method 1664A: Use of repetitive treatments with silica gel is allowed without prior EPA approval under the equivalency provision in Section 9.1.2 of EPA Method 1664A. The provision contains rigorous requirements for a demonstration of equivalency, including tests of initial precision and recovery, blanks, matrix spikes and duplicates (MS/MSD), and other data, wi...
