【Abstract】 A method for the determination of microamounts of carbon in steel by combustion in an induction furnace-infrared absorption is suggested- The purging time, blank of accelerator and decarbonizing of crucible have been investigated.It was found that the purging and analytical time are 45 and 30 sec., respectively, the blank of oxygen gas and instrument noise is 2ppm and the detection limit of the method is 10ppm of carbon.更多还原
