Sulfide acidification blowing instrument

1、 Product Introduction

1. Product principle

The sulfides in the water sample are acidified, and the generated hydrogen sulfide enters the absorption bottle/absorption color tube (100ml colorimetric tube) with the carrier gas (nitrogen) and is absorbed by the absorption solution (zinc acetate sodium acetate solution or 2% * 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

SA-LS6USulfide acidification blowing instrumentDeveloped and produced according to the standard of methylene blue spectrophotometry (iodometric method) for the determination of sulfides in water quality. *Sample pretreatment is required for the determination of sulfides in water quality.

三、 SA-LS6USulfide acidification blowing instrumentcharacteristic

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

2. The 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 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.

5. Full 304 stainless steel inner liner and bracket, with better anti-corrosion effect.

6. Concealed gas pipeline design for clearer operation and avoids pipeline entanglement.

7. Rear outlet for easy drainage.

8. Ball head flipping tube improves absorption efficiency.

9. The absorption of colorimetric tubes does not require sample transfer and can be directly tested on the machine.
