Abstract
The utility model belongs to the field of waste water treatment equipment, discloses a sample pretreatment device of a gas chromatography and mass spectrometer, and aims at solving the problems that present specified sample purification equipment is complicated in structure and high in price. The sample pretreatment device is composed of a sample inlet tube, a sample outlet tube, a spiral separation tube, a weighty-component collection tube, a waste discharge mouth and a waste discharge mouth cover. The spiral separation tube is positioned above the sample inlet tube, and the weighty-component collection tube is positioned below the sample inlet tube. The sample inlet tube, the spiral separation tube and the weighty-component collection tube are communicated with each other through a tee joint. The tail end of an upper portion of the spiral separation tube is communicated with the sample outlet tube, the waste discharge mouth is arranged at the tail end of a lower portion of the weighty-component collection tube, and the bottom of the waste discharge mouth is provided with the waste discharge mouth cover. The sample pretreatment device can further purify samples, and reduce interference of suspended matters, water and weighty-components on testing results of the gas chromatography and mass spectrometer so that the gas chromatography and mass spectrometer can be polluted less. In addition, the sample pretreatment device of the gas chromatography and mass spectrometer is simple in structure and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of gas chromatograph-mass spectrometer sample pretreatment apparatus in sewage treatment equipment field.
Background technology
Gas chromatograph-mass spectrometer is a kind of exact instrument that is used for measuring waste water organic sample composition, and this instrument is had relatively high expectations to the measuring samples degree of purification, as not containing suspension, heavy component, water or the like.Therefore before sample gets into instrument, must carry out pre-service to sample, have only the sample degree of purification to meet sampling condition after, could sample be injected in the sample cell of instrument.Special-purpose at present sample purifier apparatus complex structure costs an arm and a leg.
The utility model content
The utility model technical matters to be solved is: overcome the prior art defective, a kind of gas chromatograph-mass spectrometer sample pretreatment apparatus that can carry out purifying to measuring samples is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of gas chromatograph-mass spectrometer sample pretreatment apparatus; Mainly by the sample introduction pipe, go out appearance pipe; Spiral separation pipe, heavy component collection tube, waste discharge mouth, waste discharge flap are formed, and the sample introduction pipe is connected with the spiral separation pipe of top and the heavy component collection tube threeway of below, and spiral separation pipe upper extremity is communicated with the appearance pipe; Heavy component collection tube below end is the waste discharge mouth, and the waste discharge flap is arranged at waste discharge mouth bottom.
During work, sample tangentially slowly gets into the spiral separation pipe through peristaltic pump, thereby makes sample in the spiral separation pipe, produce the spiral rotation, and under the effect of gravity, the suspension in the sample, water, heavy component etc. all can sink down into the heavy component collection tube.Be mainly the lightweight organism through pretreated sample, flow in the receiving flask through going out appearance pipe, and in the sample suspension and heavy component, water discharge by the terminal waste discharge mouth in heavy component collection tube below.
The utility model can be further purified sample, reduces the interference to the gas chromatograph-mass spectrometer measurement result of suspension, water and heavy component, and the pollution that gas chromatograph-mass spectrometer equipment is received is littler, and the utility model is simple in structure, and is cheap.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-sample introduction pipe; 2-goes out the appearance pipe; 3-spiral separation pipe; 4-heavy component collection tube; 5-waste discharge mouth; 6-waste discharge flap; The 7-support.
Embodiment
As shown in Figure 1; A kind of gas chromatograph-mass spectrometer sample pretreatment apparatus; Mainly by sample introduction pipe 1, go out appearance pipe 2, spiral separation pipe 3, heavy component collection tube 4, waste discharge mouth 5, waste discharge flap 6 are formed, sample introduction pipe 1 is connected with the spiral separation pipe 3 of top and heavy component collection tube 4 threeways of below; Spiral separation pipe 3 upper extremity are communicated with appearance pipe 2; Heavy component collection tube 4 below ends are waste discharge mouths 5, and waste discharge flap 6 is arranged at waste discharge mouth bottom, and whole gas chromatograph-mass spectrometer sample pretreatment apparatus is fixed through support 7.
The course of work: 1, close waste discharge flap 6, pending sample is slowly squeezed into sample introduction pipe 1 by peristaltic pump.
2, behind the sample process sample introduction pipe 1, get into spiral separation pipe 3, fully swirling flow in spiral separation pipe 3, in the swirling flow process, heavy component, water, suspension and scoriform thing will fall after rise to heavy component collection tube 4 owing to gravity.
3, after swirling flow after a while, the sample after the sample that goes out 2 outflows of appearance pipe is purifying.
4, behind the full heavy component of heavy component collection tube 4 collection, open waste discharge flap 6, discharge the refuse in the heavy component collection tube 4.
5, behind the intact sample of purifying, device is cleaned the next sample of repurity with organic solvent.
Claims (1)
