PURPOSE:To improve the operation efficiency of a device for replacing the sample by equipping the device with a replacement pipe and a sample bar so that attachment, preliminary exhaustion, installation at the analysis position, aeration and removement of several samples can be performed parallel and continuously. CONSTITUTION:A device for replacing the sample is constituted of a sample replacement pipe 5 and a sample bar 12 which slides in the pipe 5 to replace the sample. The sample pipe 5 has an opeing corresponding to the analysis position located in the vacuum case of the analyzer. The sample bar 12 is equipped with sample attachment sections 13 located at given intervals. The figure indicates the stage when sample (A) is undergoing analysis, sample (B) is undergoing aeration before being removed, sample (C) is undergoing preliminary exhaustion and sample (D) is being attached to the sample bar 12. When the sample bar 12 is moved by one pitch after analysis of sample (A) is finished, sample (C) already undergoing preliminary exhaustion moves to the analysis position, sample (D) undergoes preliminary exhaustion and sample (A) is subjected to aeration and removed. Therefore, it is possible to make only time for moving the sample necessary, thereby improving the operation efficiency of the device. |
