Abstract
Provided is a flow analyzer and a flow analysis method each of which makes it possible to stably and continuously measure a sample. The flow analyzer and the flow analysis method each include: a marker introducing device (2) which is for introducing a marker into a tube (3); and a marker detecting device (5) which detects the marker and outputs a detection signal to an analyzing device (4), the analyzing device (4) acquiring analysis data on the basis of the detection signal.
Claims12
A flow analyzer comprising:
- a sampling device having a sampling device thief tube,
- an analyzing device,
- a marker introducing device having a marker introducing device thief tube, and
- a marker detecting device;
- wherein the sampling device is configured to introduce a sample into and through a tube via the sampling device thief tube;
- wherein the analyzing device is configured to analyze the sample transferred through the tube via the sampling device;
- wherein the marker introducing device is configured to introduce a marker into the tube via the marker introducing device thief tube;
- wherein the sample includes a plurality of samples, and the marker introducing device and the sampling device are configured such that the marker and, among the plurality of samples, a given number of samples, which given number is one or more, are capable of being alternately introduced into the tube;
- the introduction of the marker into the tube by the marker introducing device and the introduction of the given number of samples into the tube by the sampling device being automatically and alternately switched therebetween;
- wherein at a stage prior to introduction, into the analyzing device, of the marker and the given number of samples which sequentially flow through the tube, the marker detecting device continuously measures liquid flowing through the tube, and outputs a detection signal to the analyzing device when the marker detecting device detects the marker;
- wherein the marker detecting device is configured to detect the marker introduced into the tube via the marker introducing device;
- wherein the marker detecting device is configured to detect the marker and to output a detection signal to the analyzing device;
- wherein the analyzing device is configured to acquire analysis data of the given number of samples when the analyzing device receives the detection signal.
