Innovation of gutter oil chlorine content analyzer

KWKCL-200typeMicrocoulometric chlorine analyzer

principle

Instrument principle: The sample is carried into the cracking tube by the carrier gas and fully combusted with oxygen, where chlorine is quantitatively converted intoHCL。 HCLAbsorbed by the electrolyte and undergoing the following reaction:

HCL+Ag⁺=AgCl↓+H⁺

Reaction consumption in electrolytic dissolutionI₂orAg⁺,Causing electricityThe change in electrode potential measured by the dissolution cell is detected by the instrument and given toelectricityA corresponding electrolysis voltage is applied to the electrolysis electrode of the electrolytic cell. Electrolyze on the electrodeI₂orAg⁺Untilelectricity解池中I₂orAg⁺Restore to the original concentration. The instrument detects the amount of electricity consumed in this electrolysis process and calculates itreactionconsumeofI₂orAg⁺The quantity is used to obtain the sampleCLThe concentration.
