Device for preparing volatile organic compound standard solution

Abstract

The invention discloses a device for preparing a volatile organic compound standard solution, and specifically belongs to the field of medical instruments. The device comprises a bottom fixing plate,a fixing column, a containing cylinder, a lateral fixing block and a shaking device. One end of a containing cylinder is slidably connected with the fixing column, an end portion of the bottom fixingplate is fixed to the lower end of the fixing column, and the lateral fixing block is fixedly arranged on the bottom fixing plate and located on one side back to the fixing column; the shaking devicecomprises the lateral fixing block and a driving device; the driving device comprises a first driving rod, a sliding column, a sliding seat and a first driving mechanism; one end of the first drivingrod is hinged with one end of the containing cylinder, and the other end is hinged with the side end of the sliding column; and the sliding column is arranged on the sliding seat in a sliding mode, the sliding seat is provided with a lateral sliding groove, correspondingly, a sliding block is fixedly arranged at the end of the sliding column, and the first driving mechanism drives the sliding block to slide in the lateral sliding groove. The device has an advantage that the device can shake within a small range so that various volatile organic compounds can be uniformly mixed.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a device for configuring multi-component standard solutions of volatile organic compounds. Background technique [0002] Volatile organic compounds, commonly referred to as VOCs, refer to organic compounds with a saturated vapor pressure greater than 70Pa at normal temperature and a boiling point below 260°C at normal pressure. Most VOCs are toxic, and some VOCs are carcinogenic. They are important monitoring items in environmental testing. In the process of preparing standard solutions, one or more organic components are usually required to be mixed and prepared. [0003] However, in the process of traditional manual preparation of standard solutions, since the raw materials of organic reagents are easy to volatilize and there are many types, it is easy to cause a huge workload for the experimenters, and if the experimenters shake too much during the mixing process, it will lead t...

[0003] However, in the process of traditional manual preparation of standard solutions, since the raw materials of organic reagents are easy to volatilize and there are many types, it is easy to cause a huge workload for the experimenters, and if the experimenters shake too much during the mixing process, it will lead to low boiling point spillage of organic components, which is harmful to human health
