ZS02-3000A sulfur dioxide detector is a precision instrument designed specifically for determining the residual amount of sulfur dioxide in samples of traditional Chinese medicine, food, and other materials. It mainly consists of a heating module, a distillation module, a cooling circulating water module, and a nitrogen blowing module, which work together to achieve efficient processing and accurate detection of samples.

The following is a detailed introduction to the components of ZS02-3000A sulfur dioxide detector:

1. Heating module

Functional features: Equipped with high, medium, and low heating rate control functions, it can achieve precise control of heating efficiency. Choose a sealed infrared ceramic heating sleeve, which has good heat collection, high heating efficiency, and can prevent equipment damage caused by liquid leakage.

Working principle: By heating the sample, the sulfite series substances in the sample are converted into sulfur dioxide after acid treatment, providing necessary energy support for the subsequent distillation process.

2. Distillation module

Material advantage: Made of high borosilicate material, it has the characteristics of good heat resistance and durability. This material can withstand high temperature changes, ensuring that it will not crack or deform due to high temperatures during the distillation process.

Workflow: Under the action of the heating module, sulfur dioxide in the sample is evaporated along with water vapor and enters the distillation stage. The design of the distillation module enables sulfur dioxide to be effectively separated from the sample and enter the next processing step with the flow of nitrogen gas.

3. ZS02-3000A sulfur dioxide detector cooling circulating water module

Cooling method selection: An external cooling water circulation machine (built-in optional) can be selected to ensure stable and reliable cooling effect. The external cooling water circulation machine can adjust the cooling speed as needed to adapt to different experimental conditions.

Meaning: During the distillation process, the steam produced needs to be cooled before it can condense into a liquid, making it easier to collect and further process. The cooling circulating water module rapidly cools the distilled gas by continuously circulating cold water, condensing it into a mixture of liquid water and sulfur dioxide, thereby improving the recovery rate and purity of sulfur dioxide.

4. ZS02-3000A sulfur dioxide detector nitrogen blowing module

Gas source and control: It can be connected to an external nitrogen generator or nitrogen cylinder, and is equipped with a high-precision gas flow meter to strictly control the nitrogen blowing rate. Nitrogen is used as a carrier gas to transport the sulfur dioxide released from the sample into an absorption bottle containing hydrogen peroxide.

Importance manifestation: The nitrogen blowing process not only timely carries away the generated sulfur dioxide, avoiding its accumulation in the reaction system and affecting the reaction equilibrium, but also ensures that sulfur dioxide fully contacts and reacts with the absorbing liquid, improving the accuracy and sensitivity of detection.
