Abstract
The utility model relates to an intermittent pump sampling device, which is applicable to yield hydride. The utility model comprises a peristaltic pump1, a mixing reacting block 2, an airdraulic separator 3 and a liquid seal 5; wherein the fluid entrance of the liquid seal 5 is connected to the liquid exit of the airdraulic separator 3; the liquid seal 5 comprises an inner tube 8 and an outer tube 6 which is sleeved in the inner tube 8; the inner tube and the outer tube are provided with a gap; the upper end face 6 of the inner tube has through hole6; and the end face is lower than the fluid entrance 4 of the airdraulic separator 3. The device is able to effectively prevent useful signals from losing and improve delicacy of instruments, so as to enable sampling more precise.
Description
Technical field
The utility model relates to a kind of pump sampling device at intermittence of atomic fluorescence spectrometer device, specifically, relates to a kind of pump sampling device at intermittence that is used for the atomic fluorescence spectrometer device of hydride generation method.
Background technology
The hydride atomic fluorescence spectrometetry instrument be a kind of be exclusively used in detect some form hydride easily, to human body poisonous and harmful or beneficial trace elements.At the hydride generation method instrument of widespread use, its sample and the reductive agent overwhelming majority adopt the peristaltic pump sample introduction to add the mode of gas-liquid separator in the market, and the major advantage of this hydride producing method is simple in structure, and cross pollution is few.But because sample introduction and waste discharge simultaneously, many useful signals that reaction produces have just been drained from waste liquid before the sampling also not being able to do in time, so have reduced the sensitivity of instrument.
The utility model content
The purpose of this utility model is for addressing the aforementioned drawbacks, a kind of pump sampling device at intermittence that is used for hydride generation method being provided.
The pump sampling device at intermittence that is used for hydride generation method described in the utility model comprises peristaltic pump, hybrid reaction piece, gas-liquid separator, also has liquid packing, and the liquid inlet of this liquid packing is connected with the liquid outlet of gas-liquid separator.
The outer outer tube of pipe in managing in described liquid packing comprises and being sleeved on has the gap between the inner and outer pipes, interior pipe upper surface has through hole, and this end face is lower than the liquid inlet face of gas-liquid separator.
Sampling device described in the utility model is used for the hydride atomic fluorescence spectrometetry instrument, can control the loss of useful signal effectively, and the sensitivity that has improved instrument makes sampling more accurate.
Below in conjunction with specific embodiments and the drawings sampling device described in the utility model is further specified.
Embodiment
Fig. 1 is the structural representation of sampling device described in the utility model.
Embodiment
Referring to Fig. 1, sampling device described in the utility model comprises peristaltic pump 1, hybrid reaction piece 2, gas-liquid separator 3 and liquid packing 5.The liquid inlet of described liquid packing 5 is connected with the liquid outlet of gas-liquid separator 3.
Outer tube 7 in described liquid packing 5 comprises interior pipe 8 and is sleeved on outside the pipe has the gap between the inner and outer pipes, interior pipe upper surface 6 has through hole, and this end face is lower than the liquid inlet face 4 of gas-liquid separator 3.Waste liquid passes through the gap between ectonexine.After waste liquid covered inner tube upper surface 6, in natural gravity or external force, under the effect as peristaltic pump etc., waste liquid flowed downstream into waste liquid bottle by the through hole of upper surface 6 in inner tube 8.
The course of work of sampling device described in the utility model is as follows: sample (current-carrying) a and reductive agent b enter by peristaltic pump 1 and carry out hybrid reaction in the hybrid reaction piece 2, and the tested element hydride (gas-liquid mixed) that reaction produces is brought in the gas-liquid separator 3 by carrier gas c.The hydride gas d that enters in the gas-liquid separator 3 up enters atomizer (not looking out), and its waste liquid down enters liquid packing 5 under the nebulizer gas pressure effect.Waste liquid passes through the gap between inner and outer pipes, behind the pipe upper surface, in natural gravity or external force, flows downstream into waste liquid bottle from interior pipe under the effect as peristaltic pump etc. in waste liquid covers.
Claims (2)
1, the pump sampling device at intermittence that is used for hydride generation method, comprise peristaltic pump (1), hybrid reaction piece (2), gas-liquid separator (3), it is characterized in that also having liquid packing (5), the liquid inlet of this liquid packing (5) is connected with the liquid outlet of gas-liquid separator (3).
2, sampling device according to claim 1, it is characterized in that described liquid packing (5) comprises interior pipe (8) and is sleeved on the outer outer tube (6) of interior pipe, have the gap between the inner and outer pipes, interior pipe upper surface (6) has through hole, and this end face is lower than the liquid inlet face (4) of gas-liquid separator (3).
