Water Quality Sulfide Acidification Blower

The principle of the water quality sulfide acidification blowing instrument is as follows: sulfides in the water sample are acidified, and the resulting hydrogen sulfide is carried by the carrier gas (nitrogen) into the absorption bottle/absorption colorimetric tube, where it is absorbed by the absorption solution (zinc acetate-sodium acetate solution or 2% sodium hydroxide solution). The absorbed sulfide ions in the absorption bottle/absorption colorimetric tube are then analyzed and measured using the appropriate analytical method.

The water quality sulfide acidification blowing instrument is developed and manufactured in accordance with the standard for the determination of water quality sulfides using the methylene blue spectrophotometric method (iodometric method), meeting the sample pretreatment requirements for the determination of water quality sulfides.

• The hydrochloric acid inlet, gas inlet, and outlet are integrated into a single unit yet remain independent, ensuring that operations do not interfere with one another.

• Constant-temperature water bath heating with a rapid automatic temperature control system, allowing the heating temperature to be manually set.

• The sample rack and gas distribution system are adjusted via a height-adjustable knob, allowing for easy installation of samples on the front and convenient operation.

• The nitrogen flow rate for each sample can be independently controlled, adjusted, or shut off. The needle valve gas flow meter accurately controls and displays the total gas consumption.

• Large-capacity reaction flasks enable simultaneous processing of multiple samples.
