The spectrometer cannot detect sulfur

Home / The spectrometer cannot detect sulfur

Most spectrometer problems stem from three things: incorrect calibration, poor sample prep, or hardware wear. If your UV reading is drifting or results are inconsistent across runs, it's time to recalibrate using certified standards. Traditional approaches use chemical reagents that react with sulfur compounds to produce measurable changes, such as color. The Thermo ScientificTM ARLTM PERFORM'X Series Spectrometer used in this analysis was a 4200-watt system. Based on my preliminary literature search it appears development for such a method may be difficult.
