Problems solved by technology

[0002] The content of volatile organic compounds in the air is very low, but people breathe the air all the time. Volatile organic compounds are very harmful to human health, and they are also gaseous substances that form ozone. It is necessary to detect the content of volatile organic compounds in the air. The existing The sensitivity of the detection instrument cannot meet the requirements, and it needs to be concentrated and processed before the sample can be detected

Abstract

The invention relates to an automatic sampling and cleaning instrument for containers, which solves the problems of separation of self-sampling and cleaning mechanisms of the containers, cross contamination of samples between the containers, low working efficiency and low sample analysis quality. In a sample injection state, a three-way valve connects the first-Nth group of containers with one channel of a multi-channel valve respectively, the first-Nth switch is closed, the multi-channel valve connects a sample processing sample injector with the first-Nth group of containers respectively, when the first-Nth group of containers need to be cleaned, the connection of the three-way valve of the first-Nth group of containers and the multi-channel valve is closed, the first-Nth group of containers are vacuumized by a vacuum pump through the first-Nth switch and the first-Nth branch pipe, after the vacuum pump is disconnected from the first-Nth group of containers, the first-Nth switch is turned on, the first-Nth branch pipe is connected with a main pipe, after nitrogen is filled into the containers, the switches are turned off, the containers are vacuumized by the vacuum pump, nitrogen filling and vacuumizing are repeated for multiple times, and cleaning of the containers is completed.

Description

technical field [0001] The present invention relates to sampling and cleaning devices for containers for collecting and holding samples. Background technique [0002] The content of volatile organic compounds in the air is very low, but people breathe the air all the time. Volatile organic compounds are very harmful to human health, and they are also gaseous substances that form ozone. It is necessary to detect the content of volatile organic compounds in the air. The existing The sensitivity of the detection instruments cannot meet the requirements, and it needs to be concentrated and processed before the sample can be detected. Due to the characteristics of the components, the general container has adsorption on the components and cannot hold the sample well. It is necessary to have an inert container to collect and hold the sample, and then install this container on a device to realize automatic sampling; In addition, After the sample injection is completed, it is necess...
