A sample analyzer comprising: a sample dispenser for dispensing a sample into a reaction container; a sample transporter for sequentially transporting a plurality of reaction containers along a transporting path; a processing station including a plurality of processing sections (110a+111a, 110b+111b, 110c+111c, 110d+111d) and a transferring section arranged to transfer a reaction container between the sample transporter and the processing sections; and a controller configured to execute a sample processing operation for a sample, the sample processing operation including: (i) dispensing, by the sample dispenser, the sample into a reaction container; (ii) transporting, by the sample transporter, the dispensed reaction container along the transporting path; (iii) transferring, by the transferring section, the transported reaction container from the sample transporter to any of the processing sections; (iv) carrying out, by the processing section, a process on the sample in the reaction container; and (v) transferring, by the transferring section, the reaction container from the processing section to the sample transporter after completing the process, wherein the controller is configured to sequentially initiate the sample processing operations for a plurality of other samples at predetermined time intervals while continuing the sample processing operation for the sample, wherein the plurality of processing sections (110a+111a, 110b+111b, 110c+111c, 110d+111d) include first and second processing sections, the sample dispenser is configured to dispense a sample so that one cycle including a first dispensing timing and a second dispensing timing is periodically repeated, the transferring section is configured to transfer a reaction container in which a sample is dispensed at the first dispensing timing to the first processing section, and is configured to transfer a reaction container in which a sample is dispensed at the second dispensing timing to the second processing section, characterized in that the controller is configured to determine whether a problem occurs at any of the processing sections, and the controller is configured to control the sample dispenser so that when a problem occurs at the first processing section, the sample dispensing is skipped at the first dispensing timing. a sample dispenser for dispensing a sample into a reaction container;
