In order further to optimize technique scheme, in the present embodiment, also comprise the encoder feedback system for further control sample introduction needle 3 sample position, thereby more accurately, more stably control the sampling process of mechanical arm.
In the present embodiment, when testing sample easily volatilized, sample bottle 14 can add O-ring seal or the gland bonnet that prevents the testing sample volatilization according to real needs.
In order to reduce the artificial participation in the sample analysis process, improve testing efficiency, although automatic sampler can replace the process of the artificial sample introduction in the sample analysis process, but, just simply provide sample introduction to analytical instrument, and the data of analytical instrument need manual record, and the sample message of record is corresponding one by one on needs and the sample bottle 14, this process needs artificial the participation equally, and spends a large amount of manpowers, easily makes mistakes.
Therefore, based on the automatic sampler in above-described embodiment, the present invention also provides a kind of sample introduction test macro, this sample introduction test macro comprises the automatic sampler in above-described embodiment, also comprise the analytical instrument that testing sample is tested, wherein, control system control sample introduction needle 3 arrives analytical instrument with testing sample through going out the sample Pipeline transport, analytical instrument is tested by control system control, and test data is transferred to control system records, shows and preserve.Thereby, by sample introduction test macro provided by the invention, can reach the purpose that minimizing manually participates in and increases work efficiency in the sample analysis process, realized robotization, the unmanned management in laboratory in the sample introduction test process.
In order further to optimize technique scheme, the sample introduction test macro that the embodiment of the invention provides also comprises for the information on the typing sample bottle 14, and it is reached the Message Entry System of control system.Wherein, Message Entry System can be by two-dimension code or bar code scan, infrared read or the mode such as camera identification realizes the typing of testing sample information.But for a person skilled in the art, the mode of Message Entry System entry information has multiple, and therefore, the present invention does not do restriction to this.
In order further to optimize technique scheme, in the sample introduction test macro that the embodiment of the invention provides, also comprise by the printing section of control system with test data generated data form and printing.
Therefore as seen, in the sample introduction test macro that the embodiment of the invention provides, control system is not only controlled each solenoid valve action in the automatic sampler, and the sampling action of control mechanical arm and sample introduction needle 3, and, the work of many analytical instrument is also controlled, coordinated to control system, simultaneously, also has the functions such as data query, data-printing, data management.In fact, control system is at PC(Personal Computer, personal computer) or industrial computer on operation and be used for to coordinate automatic sampler and the software of analytical instrument.Therefore, the functions such as whole sample introduction, test, Data Enter, data query and management of the sample introduction test macro that provides of the embodiment of the invention realize all needing to rely on computer.
The workflow of sample introduction test macro provided by the invention sees also Fig. 1, wherein, solid black line arrow refers to the direction of data upload, and the mode of data upload comprises wireless blue tooth, Ethernet, USB(Universal Serial Bus, USB (universal serial bus)), 232 interfaces or 485 interfaces etc.; The hollow large direction of arrow refers to the testing process of testing sample.
To sum up, as a preferred version, the method for testing of sample introduction test macro provided by the invention specifically may further comprise the steps:
Steps A: the information of corresponding testing sample record testing sample wherein on sample bottle 14;
Step B: by the information on the Message Entry System typing sample bottle 14, and reach control system;
Step C: sample bottle 14 is placed on the sample bottle rack 6 according to the order during entry information among the step B;
