Absorbance of electromagnetic energy by the aqueous stream is measured in an optical sample cell with pulsed light at a wavelength of 190nm ± 10nm. A value of total organic carbon from the measured absorbance is calculated without absorbance or fluorescence measurement at any other wavelength.2/6 237 243 245 235 E 2070 217231Counter out 21Fig 23 233 219 022 -239 Filte ---Display F Ite Filter I 2091 221 V~ilt~lte227 211 ./208 215 /05 -- 225 201 ----.241 207 203 Fig. 2
