Doctoral experiment
Thread Content
Guys, at what level of sulfur content can a doctor’s experiment be considered successful?
For the Drabek test, it’s not possible to rely on the total sulfur content; in our case, if the total sulfur level in MTBE is less than 30 ppm, the Drabek test fails. What matters is the presence of thiophenes, thioethers, and thiols – total sulfur encompasses many different forms, so it’s best to conduct a comprehensive analysis
The doctoral test requires that the thiol sulfur content be below 10 ppm (a mass fraction of no more than 0.001%)
The problem is that my total sulfur content is only 2; I still fail the doctoral experiment
I’ve heard of the “doctoral experiment” for the first time; could you explain which specific experiment it refers to and why it’s called that? Very curious
I can’t explain it in detail; in short, it’s used to detect thiol and hydrogen sulfide. Ask Baidu
Using the microcoulometry method or the gas chromatography method
The requirements for thiols and sulfur in gasoline are: 1, successful completion of the Dr. test, 2, total sulfur content less than 10 ppm. So, it should be 10ppm.
