Product details

Product Description:

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. The water quality sulfide acidification blowing instrument is developed and produced according to the 2022 new national standard for the determination of sulfides in water quality - methylene blue spectrophotometric method (canonical method). Sample pretreatment is required for the determination of sulfides in water quality.

Product Features:

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

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

3. 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.

4. Adjust the sample rack and gas distribution system by fixing the lifting position knob, rotate the lifting of the sample rack, and install the sample on the front for easy operation.

5. The hydrochloric acid inlet, gas inlet, and outlet are integrated and separated from each other, without interfering with the operation.
