A sample analyzer which transports and analyzes samples, comprising: a first measurement apparatus which measures samples; a second measurement apparatus which is arranged downstream, in a transport direction, from the first measurement apparatus, and which measures samples; a transporting apparatus which transports samples to a first supply position for supplying a sample to the first measurement apparatus, and to a second supply position for supplying a sample to the second measurement apparatus, wherein the transporting apparatus is configured such that the first supply position is connected to the second supply position by means of a single linear transport path, wherein the transporting apparatus is configured to transport a rack having a plurality of sample container holders for holding a sample container, and wherein an interval between the first supply position and the second supply position is shorter than or equal to an interval between sample container holders at two ends of the rack, the sample analyzer being characterised in that it comprises a controller configured to control transportation of a first sample present at the first supply position, in accordance with a processing status of a second sample present at the second supply position, wherein the controller is further configured, if the second sample at the second supply position needs to be aspirated, to disallow transportation of the rack if an aspiration of the first sample at the first supply position has been completed until an aspiration operation of the second sample at the second supply position has been completed, and wherein the controller is further configured to, after the first sample at the first supply position has been aspirated and if the second sample at the second supply position has been aspirated or does not have to be aspirated, transport the rack downstream in the transport direction by the interval between adjacent sample container holders of the rack. a first measurement apparatus which measures samples; a second measurement apparatus which is arranged downstream, in a transport direction, from the first measurement apparatus, and which measures samples; a transporting apparatus which transports samples to a first supply position for supplying a sample to the first measurement apparatus, and to a second supply position for supplying a sample to the second measurement apparatus, wherein the transporting apparatus is configured such that the first supply position is connected to the second supply position by means of a single linear transport path, wherein the transporting apparatus is configured to transport a rack having a plurality of sample container holders for holding a sample container, and wherein an interval between the first supply position and the second supply position is shorter than or equal to an interval between sample container holders at two ends of the rack, the sample analyzer being characterised in that it comprises a controller configured to control transportation of a first sample present at the first supply position, in accordance with a processing status of a second sample present at the second supply position, wherein the controller is further configured, if the second sample at the second supply position needs to be aspirated, to disallow transportation of the rack if an aspiration of the first sample at the first supply position has been completed until an aspiration operation of the second sample at the second supply position has been completed, and wherein the controller is further configured to, after the first sample at the first supply position has been aspirated and if the second sample at the second supply position has been aspirated or does not have to be aspirated, transport the rack downstream in the transport direction by the interval between adjacent sample container holders of the rack.
