Proceed as described in Sectionsusing an oil sample of similar type to the unknown sample and of accurately known sulfur content. Its adjustment range is not less than 20 mm. The combustion products are passed aastm an absorber containing an acid solution of potassium iodide and starch indicator.

ASTM D – 03 Standard Test Method for Sulfur in Petroleum Products (High-Temperature Method)

Add a few drops of the appropriate standard KIO3 solution Table 2 to produce a faint blue color. For example, V2O5 has a definite effect and should be included if used for unknowns as recommended in the ast, with the resistance-type furnace.

ASTM D1552 – 16E1

Determination of Standardization Factor: Miscellaneous Apparatus Specific combustion assemblies require additional equipment such as crucibles, combustion boats, crucible lids, boat pushers, separator disks, combustion tubes, sample inverters, oxygen flow indicator, and oxygen drying trains. Connect the exit end of the combustion tube to the absorber with glass tubing, using gum rubber tubing to make connections.


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. For IR detectiondetermine and load the microprocessor with the calibration factor for the particular type of sample to be analyzed lubricating oil, petroleum coke, residual fuel as recommended by the manufacturer.

The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. Two of the three procedures use iodate detection ; one employing an induction furnace for pyrolysis, the other a resistance furnace.

SC 3 laboratories conducted in Septemberthey are being deleted.

A framework, a supreme code of conduct cherishes us every day to serve the world better.

Webprint Printed and bound. Take samples in accordance with the instructions in Practice D A microprocessor calculates the mass percent sulfur from the sample weight, the integrated detector signal and a predetermined calibration factor.

Adjust the buret to zero. Add 65 mL of HCl 3 6 and 2 mL of starch-iodide solution to the absorber. In some cases the presence of sulfur compounds is beneficial to the product and monitoring the depletion of sulfur can provide useful information. Adjust the oxygen flow rate to 2 6 0. Get a phone call within 2 hours to give back. Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Potassium Alum Aluminum Potassium Sulfate.


Sulfur in Hydrocarbons

Nitrogen does not interfere with the IR system. Most sulfur present is combusted to SO2 which is then measured with an infrared detector after moisture and dust are removed by traps. Potassium Iodate, Standard Solution 0.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Starch-Iodide Solution—Make a paste by adding 9 g of soluble starch to 15 mL of water. Run a suitable analytical quality control sample several times daily. The additional equipment required is dependent on the type of furnace used and is available from the manufacturer of the specific combustion unit.

Cool the mixture, add 15g of potassium iodide KIand dilute to 1 L with water. Each holder can be adjusted independently. Preparation of Apparatus Induction-Type Furnace Assemble the apparatus according to the instructions furnished by the manufacturer.

Beret, standard mL or automatic types available from the manufacturers of the specific combustion units, are suitable. The calibration factor is determined using standards approximating the material to be analyzed.
