Description
Technical field
The present invention relates to a kind of Sample pretreatment enrichment facility, particularly a kind of portable sample concentrating instrument carrying air pump single-pipeline and control.
Background technology
In Food Safety Analysis field, in order to obtain the residual quantity of target compound, needing to treat sample and originally carrying out pre-service, a wherein important job concentrates pre-treatment sample exactly.Current modal pre-treatment enrichment facility is mainly Nitrogen evaporator, and traditional Nitrogen evaporator process sample size is few, and volume is comparatively large, and needs to rely on extraneous source of the gas practical function, and portability is poor, can not meet on-the-spot sample analysis demand in enormous quantities.Therefore, need to develop a kind of good portability, detect the pre-treatment concentrating instrument that sample size is large.
At present, sample concentration instrument disclosed in prior art, Air-conditioning system is provided with in instrument box, achieving can outdoor execute-in-place, processes the object of multiple sample simultaneously, but its gas circuit controls to adopt overall control, branch road pipe distributes air-flow, different pipeline air-flow size is easily inconsistent, and be not easy to regulate, applicability is poor.
Summary of the invention
For solving prior art Problems existing, the invention provides a kind of sample concentration instrument, it comprises the housing supporting total unit, there is the support for holding sample tube of multiple sample pore, temperature control system, air source device system, described temperature control system comprises the heating arrangement for heating sample tube on support, for the switchgear of control temperature, described air source device system comprises the air pump for pressurizeing to gas, for controlling the switchgear of air pump, for distributing the air guide panel of air-flow, the gas blow pipe for deriving gas of sample pore is aimed in gas outlet, and for regulating the stop means of air guide panel height, described air guide panel intersects and is provided with multiple gas blow pipe, described air pump, air guide panel, gas blow pipe successively airtight connection communicates, described stop means is arranged between air pump and air guide panel, for regulating the height of air guide panel, all airtightly between described each gas blow pipe and air guide panel be connected with gas speed regulating control valve.
Described gas speed regulating control valve, comprise control hand wheel, spool, valve body, described spool is threaded with between valve body, and spool front end and valve body contact place are provided with O-ring seal.
Attemperating unit can also have temperature indicating device, and it has the temperature inductor of induction heating apparatus temperature.
Described support and heating device shell all can adopt the good stainless steel of heat conduction and heat radiation.
Described sample concentration instrument can also have air filter, and it can be arranged between sample concentration instrument air intake and air pump or between air pump and air guide panel.
Sample concentration instrument of the present invention carries air pump, good portability, can adapt to the detection demand of the varying environments such as outdoor, controls to replace gas circuit entirety control with single gas circuit, the different demands of different sample to tolerance size can not only be adapted to, also can avoid the defect adopting overall single flow speed control valve reliability not good.
