Contamination polyphase metabolism germiculture and product collection interface device used for analyzer

Abstract

The invention relates to a contamination polyphase metabolism germiculture and product collection interface device used for an analyzer, aiming at solving the problem of on-line detection combined use. The technical proposal is as follows: the contamination polyphase metabolism germiculture and product collection interface device consists of a germiculture device and a cooling dewatering device which are communicated with each other. The germiculture device comprises a bottle body, a bottle cap and a liner tube which is arranged in the bottle body. The bottle cap is provided with two switching valves. Two pipelines are communicated with the inside and the outside of the bottle cap by the switching valves. Two pipelines at the outer end of the bottle cap are provided with a throttle switch. Two pipelines at the inner end of the bottle cap are extended into the liner tube with different lengths. The pipeline with longer extended end is a gas-carrier inlet pipeline, and the pipeline with shorter extended end is a gas-carrier outlet pipeline. A sealing ring is arranged between the bottle body and the bottle cap. The contamination polyphase metabolism germiculture and product collection interface device satisfies the requirements of germiculture and gaseous production collection and also has the function of being convenient for on-line use combined with a subsequent analyzer at the same time, thus facilitating the analytic determination of the product. The contamination polyphase metabolism germiculture and product collection interface device can provide a proper test interface device for studying the biogeochemical characteristics of arsenic and other toxic elements and obtain exact real-time analysis data.

Description

technical field

[0001] The invention relates to a bacterial culture interface device for collecting pollutant metabolites used in conjunction with analytical instruments, especially for the generation and collection of gas, liquid and solid multiphase bacterial metabolites of toxic element arsenic, which belongs to chemical detection and analysis technology field. Background technique

[0002] The toxic element arsenic is one of the most concerned pollutants in the international environmental field, with a wide range of pollution and high toxicity. Arsenic in the environment can form soluble organic arsenic compounds such as monomethylarsenic (MMA) and dimethylarsenic (DMA) through the biomethylation process and enter the liquid or solid phase. The latest research also shows that bacterial or microbial activity may also convert soluble inorganic arsenic to arsine, AsH 3 , Methylarsenic (CH 3 )AsH 2 , Dimethylarsenic (CH 3 ) 2 AsH and trimethylarsenic (CH 3 ) 3 As and...
