3, atomizer flame pulsation influences the mensuration precision of instrument;
4, the tightness of pump line briquetting adjusting directly influences the serviceable life of the test performance and the pump line of instrument, and the human factor influence is bigger.
The interrupted shortcoming that flows sampling device is:
1, pump line is tired easily impaired, thereby causes the poor stability of long-term sample introduction;
2, atomizer flame pulsation influences the mensuration precision of instrument;
3, the same with flow injection, the human factor influence is bigger.
The utility model content
The purpose of this utility model provides a kind of sequential injection sampling device that is used for atomic fluorescence spectrometer, and this device can keep the advantage of flow injection and the interrupted two kinds of sampling devices that flow, and has eliminated these the two kinds shortcomings that device exists simultaneously again.
The purpose of this utility model is achieved in that
The sequential injection sampling device that is used for atomic fluorescence spectrometer described in the utility model comprises the cleaning fluid pipe, sampling pump, and sampling ring, the sample introduction pipe, the reductive agent pipe, gas-liquid separator is used for the peristaltic pump of effluent discharge.Described sampling pump is a ram pump, also have two-position valve and multi-position valve, described cleaning fluid pipe, ram pump is connected with two-position valve, sampling ring is arranged between two-position valve and the multi-position valve, each valve position of all the other of multi-position valve is connected with gas-liquid separator with sample introduction pipe, reductive agent pipe respectively, and described gas-liquid separator is connected with peristaltic pump with atomizer, is connected with the carrier gas pipe in the connecting line of multi-position valve and reactor.
It further improves is also to have reactor, two-position valve, ram pump and automatic sampler sample disc, described reactor and two-position valve are arranged between the pipeline of multi-position valve and reductive agent pipe, reactor is connected with gas-liquid separator again, ram pump is connected with two-position valve, and described automatic sampler sample disc is connected with the sample introduction pipe.
The sequential injection sampling device that is used for atomic fluorescence spectrometer that adopts the utility model to provide, except eliminating the defective that flow injection sampling device and the interrupted sampling device that flows exist, keep outside the advantage of these two kinds of sampling devices, also can reduce sample significantly, cleaning fluid, the consumption of reagent such as reductive agent and gas (10-30% that is about preceding two kinds of required amount of reagent of sampling device): and because its sample introduction precision is very high, can directly use the on-line automatic configuration standard series of single-point concentration, online enriched sample such as is diluted automatically at function, improve the precision and the detection limit of instrument, improved robotization and " foolization " degree of instrument.In addition, can realize the semi-automation of atomic fluorescence spectrometer with the sequential injection system of single syringe pump; Can realize the full-automation of atomic fluorescence spectrometer with the sequential injection system of double injection pump, improve the service efficiency and the practicality of atomic fluorescence spectrometer, be a kind of more satisfactory sampling device that is used for atomic fluorescence spectrometer.
