PURPOSE:To enable a quick unmanned analysis of multiple samples by a computer control of automatic devices for weighing, melting, filtering and the like of the sample in combination with a high frequency induction coupling plamsa beam spectrochemical analyzer (ICP). CONSTITUTION:When a solid sample such as steel is analyzed with an ICP, a powder sample is placed into a sample container B on an automatic sampler A. As the sampler A moves on to an automatic balance C, the balance C weighs the weight of the sample lifting the container B and the value thereof is memorized into a computer. Then, a solenoid valveIis opened and a sample melting tank E is rendered vacuum inside with a vacuum pump F by way of a cooler Q, a cleaning bottle H and a vacuum reservoir G. Then, a solenoid valve J is opened and a sample in the container B is sucked into a tank E via a tube D. Then, the container B is weighed again and the weight of the sample in the tank E is memorized into the computer depending on a defference from the previously measured weight. After a desalted water, 1-3 types of acids and an internal standard liquid are added into the tank E separately from tanks R, M, N, O and S, the sample is heated with a heater P to disolve. Then, the sample is stored into a vessel V through a filter U and a desalted water is put thereinto from a desalting water bottle Y if necessary. Then, the vessel is sent to an ICP device. |
