An online dedicated generator is an automated device that can continuously and stably produce and directly supply specific gases or aerosols.It replaces traditional steel cylinder gas sources by integrating advanced physical, chemical, or mechanical principles, providing efficient, safe, and intelligent gas solutions for modern industrial production, environmental monitoring, and laboratory analysis.

　　1、 Core working principle and technical characteristics

There are various types of online dedicated generators, but their core goal is to generate the required media in real-time according to needs.

The working principle varies depending on the type. For example, hydrogen generators mainly use electrolytic pure water technology to decompose water into high-purity hydrogen and oxygen under the action of catalysts. Air generators are usually based on physical processes such as compression, cooling, and drying, and use key technologies such as membrane separation or pressure swing adsorption (PSA) to separate high-purity nitrogen or oxygen from ambient air. The working principle of an aerosol generator is that under the action of high-speed airflow at the jet outlet, negative pressure is formed at the bacterial liquid spray outlet, and the bacterial liquid in the generator is sucked to the nozzle, where it is fragmented or dispersed into countless aerosol particles by the high-speed airflow before being sprayed out.

　　2、 These generators generally have several outstanding technical features:

1. High automation and intelligence: Modern generators are usually equipped with microcontrollers or intelligent control systems, which can achieve functions such as automatic water replenishment, fault diagnosis, pressure monitoring, remote communication, etc., greatly reducing manual intervention.

2. Safe and reliable: The equipment integrates multiple safety measures, such as overvoltage protection device, automatic power-off for hydrogen leakage, anti backflow device, and low water level protection, ensuring the safety of long-term continuous operation.

3. Efficient and Stable Output: Adopting designs and processes such as cylindrical widened electrolytic cells, efficient filtration technology, and pressure stabilization systems, the purity of the output gas is not degraded and the flow rate is stable, which can meet the requirements of 24-hour uninterrupted operation.

　　3、 Widely applicable fields

Online dedicated generators, with their unique advantages, have penetrated into multiple key areas:

1. Environmental monitoring: Online hydrogen generators and air generators are specially designed to meet the requirements of online volatile organic compound (VOC) monitoring equipment, and are key components of environmental air quality and pollution source monitoring systems.

2. Industrial Process and Quality Control: Used in industries such as chemical, electronic manufacturing, and food processing to provide high-purity gases required for processes or conduct integrity testing in clean environments.

3. Laboratory analysis: As a safe gas source for analytical instruments such as gas chromatography (GC), it replaces high-pressure steel cylinders and provides pure and stable carrier gas or fuel gas for the laboratory.

4Summary and Outlook

The online dedicated generator, with its immediate production and use characteristics, eliminates reliance on traditional steel cylinders, avoids the pain and potential risks of handling, and reduces operating costs. With the continuous advancement of technology, its intelligence, integration, and reliability will be further improved, and it will continue to be a crucial basic equipment in various industries, providing solid support for the sustainable development of industrial automation, environmental monitoring, and scientific research.
