- octane (by volume) into the flask

to a net weight of approximately 50 gm and record the

weight. This "Stock Sta ndard" contains approximately 10

mg/gm sulfur. The actual sulfer concentration can be ca lculated as follows:

Sulfur from thiophene (gm) = Weight of thiophene

*32.06* purity/84.14

Sulfur from 2

- methylthiophene (gm) = Weight of

2

- methylthiophene *32.06* purity/98.17

Sulfur concentration of Stock Standard (gm/gm) = (sulfur

from thiophene + sulfur from 2

- methylthiophene)/net

weight of the stock standard

Multiply the sulfur concent ration by 1000 to convert the unit to mg/gm.

Preparation of Calibration Standards Pipet 2.5 ml of the

Stock Standard to 250 ml flask and dilute with the "mixed

solvent" to the mark. The "Diluted Standard" contains

approximately 100 mg/kg sulfur. Prepare 5, 10, 20, 30, 50,

75 ppm calibration standards by pipetting 5, 10, 20, 30, 50,

75 ml of the Diluted Standard into a 100 ml flask, respe ctively, and diluting with the "mixed solvent" to the mark.

The actual concentration of the calibration standard should

be determined from the stock standard. The standards with

concentration ranging from 5 to 100 ppm and the "mixed

solvent" are to be used for calibrating the instrument.

method may be used following a determi nation by the

executive officer that the other method produces results

equivalent to the results with the specified method.
