Abstract

The invention relates to a sample concentrator. The sample concentrator comprises a housing for supporting the whole structure unit, a support which is provided with multiple sample pipe holes and is used for receiving a sample pipe, a temperature control system and a multiple-path gas supply system. The temperature control system comprises a heating device and a switch device. The multiple-path gas supply system comprises an air pump, a switch device, a gas guide panel, gas blowpipes and a limiting device. The gas guide panel is crosswise provided with the multiple gas blowpipes. The air pump, the gas guide panel and the multiple gas blowpipes are orderly and hermetically communicated. The limiting device is arranged between the air pump and the gas guide panel and is used for adjusting height of the gas guide panel. A gas speed adjustment control valve is seal-connected to each one of the gas blowpipes and the gas guide panel and is arranged between the gas blowpipe and the gas guide panel. The sample concentrator utilizes single-air passage control and satisfies different gas amount requirements on treatment on different samples.

Description

technical field

[0001] The invention relates to a sample pretreatment concentration device, in particular to a portable sample concentrator with an air pump and single pipeline control. Background technique

[0002] In the field of food safety analysis, in order to obtain the residual amount of the target compound, the sample to be tested needs to be pretreated, and one of the important tasks is to concentrate the pretreated sample. At present, the most common pre-treatment concentration device is mainly nitrogen blowing instrument. The traditional nitrogen blowing instrument has a small sample volume and a large volume, and needs to rely on an external gas source to realize its functions. The portability is poor, and it cannot meet the needs of large-scale sample analysis on site. Therefore, it is necessary to develop a pretreatment concentrator with good portability and a large amount of detection samples.

[0003] At present, the sample concentrator disclosed in the prio...
