Product details

Description of products

1. Product principle

The sulfides in the water sample are acidified, and the generated hydrogen sulfide enters the absorption bottle/absorption color tube with the carrier gas (nitrogen) and is absorbed by the absorption solution (zinc acetate sodium acetate solution or 2% sodium hydroxide solution). The corresponding analysis method is selected to analyze and determine the sulfur ions absorbed in the absorption bottle/absorption color tube.

2. Product Usage

The water quality sulfide acidification blowing instrument is developed and produced according to the standard of methylene blue spectrophotometry (iodometric method) for the determination of water quality sulfides. Meet the sample pretreatment requirements for sulfide determination in water quality.

3. Product execution standards

New National Standard HJ1226-2021 "Determination of Sulfides in Water Quality - Methylene Blue spectrophotometric Method" for 2022

Product characteristics 

1. Large capacity reaction bottle, capable of processing multiple samples simultaneously.

2. The hydrochloric acid inlet, gas inlet, and outlet are integrated and independent of each other, and the operation will not interfere.

3. Constant temperature water bath heating, equipped with a fast automatic constant temperature control system, and the heating temperature can be manually set.

4. The sample rack and gas distribution system are adjusted by a fixed knob for lifting and rotating the sample rack. The sample is installed on the front for easy operation.

5. The nitrogen flow rate of each sample is independently controlled and adjusted or closed, and the needle valve gas flowmeter accurately controls and displays the total gas consumption.
