Abstract
The disclosure concerns a method for operating an automated analyzer, including transporting a liquid containing a plurality of particles into a chamber, such as a reactor chamber and/or measuring cell chamber of the analyzer, introducing a gas or gas mixture, for example, air into the chamber, such as through the liquid present in the chamber so that the particles in the liquid are stirred up, and subsequently draining at least part of the liquid from the chamber through a fluid line ending in the chamber and an open valve arranged in the fluid line.
Claims17
A method for operating an automated analyzer, comprising:
- transporting a liquid containing a plurality of particles into a chamber of an automated analyzer;
- introducing a gas or gas mixture into the chamber through the liquid present in the chamber such that the particles in the liquid are stirred up;
- and
- draining at least a portion of the liquid from the chamber through a first fluid line connected to the chamber and through an open valve arranged in the first fluid line.
An analyzer for determining a parameter value of a liquid, the analyzer comprising:
- measuring and control electronics;
- a chamber embodied as a measuring cell chamber and/or a reactor chamber;
- a fluid line connected to the chamber, including a valve arranged in the fluid line to enable transport of a gas or a liquid in an open state and to enable blocking of the transport of the gas or the liquid in a closed state;
- a first fluid flow path including a first valve device structured to selectively block or open the first fluid flow path, the first valve device fluidically connecting a sampling site or a sample recipient vessel to the chamber;
- a pump arranged in the first fluid flow path;
- and
- a second fluid flow path including a second valve device structured to selectively block or open the second fluid flow path, and the second valve device fluidically connecting the chamber to a gas reservoir, wherein the measuring and control electronics are programmed to control the analyzer, including the pump, valve, first valve device and second valve device, to perform the method.
