1. Product introduction

The JC-GGC800 water quality sulfide -acidification air blowing instrument is developed and produced by our unit according to the national ecological environment standard of the People's Republic of China : HJ 1226-2021 Determination of water quality sulfide -methylene blue spectrophotometry standard. Meet the sample pretreatment needs of water sulfide determination. It is suitable for the determination of sulfide in surface water, groundwater, domestic sewage and industrial wastewater. The product has the characteristics of easy control, simple and quick operation and so on.
When the sampling volume is 200 ml and a 10 mm optical path cuvette is used, the detection limit of the method is 0.01 mg/L, and the lower detection limit is 0.04 mg/L;

When using a 30 mm optical path cuvette, the detection limit of the method was 0.003 mg/L, and the lower limit of determination was 0.012 mg/L.

Note: The 30 mm optical path cuvettes are only used for the determination of groundwater or low-concentration seawater below the first-class standard, and the "acidification-distillation-absorption" method should be used for the pretreatment method.
