Most sulfur present is combusted to SO2 which is then measured with an infrared detector after moisture and dust are removed by traps. The furnace work coil should have a minimum output of W; the minimum input rating of the furnace must be W.

NOK 1 ,00 excl. The moment new editions of the standards you monitor are released, changes d1552 made, or appendixes are published, you will be alerted by email.

A microprocessor calculates the mass percent sulfur from the sample weight, the integrated detector signal and a predetermined calibration factor. Connect the exit end of the combustion tube to the absorber with glass tubing, using gum rubber tubing to make connections. Adjust the oxygen flow to 1 6 0.
