Description

Technical Field

[0001] This utility model relates to the field of gas chromatography technology, and in particular to a hazardous substance residue analyzer. Background Technology

[0002] In today's era of heightened concerns regarding food and drug safety and environmental protection, hazardous substance residue analyzers have become crucial equipment for quality control and safety assurance. Traditional hazardous substance residue analyzers are typically fixed structures, mostly housed in laboratories. They often lack a dedicated mobile design at the base, relying solely on manual handling for relocation. This makes them extremely inconvenient to move when facing diverse testing scenarios such as food production workshops, pharmaceutical warehouses, and environmental monitoring sites, hindering their ability to quickly respond to testing needs in different locations.

[0003] In terms of power supply, traditional measuring instruments mostly rely on external fixed power sources. Once in the field, in areas with unstable power supply, or in the event of a power outage or other emergencies, they cannot operate normally, forcing the interruption of testing work. Regarding operating space, the operating platform of traditional measuring instruments has a fixed height and cannot be adjusted according to the operator's height and operating habits. This makes operators prone to fatigue during prolonged operation, reducing work efficiency, and may even lead to testing errors due to operational inconvenience. Utility Model Content
