1. Product introduction

1. Product principle

The sulfide in the water sample is acidified, and the generated hydrogen sulfide enters the absorption bottle/absorption color developing tube with the carrier gas (nitrogen) and is absorbed by the absorption solution (zinc acetate-sodium acetate solution or 2% sodium hydroxide solution). The analytical method is used to analyze and measure the sulfide ions absorbed in the absorption bottle/absorption color developing tube.

2. Product use

The JC-GGC400 water quality sulfide-acidification gas blowing instrument is developed and produced according to the standard of water quality sulfide determination-methylene blue spectrophotometry (iodometric method). Meet the sample pretreatment needs of water sulfide determination.

3. Product implementation standards
