The present disclosure relates to a capsule for preparing a solution for use with a measuring device for determining a measurand that depends on a concentration of at least one analyte in a sample. The capsule includes a wall completely enclosing an interior, at least one substance accommodated within the interior, and at least one stirring body. The present disclosure also relates to a system, which includes at least one capsule and a liquid container closed in a liquid-tight manner, which contains a predetermined volume of a liquid containing a solvent. In addition, the wall of the capsule is formed from a material which dissolves at least partially in the solvent.

Method and system for preparing a solution

The present disclosure includes an automatic analyzer and a method for the determination of a measurand dependent upon the concentration of one or more ingredients of a measuring fluid. The analyzer includes a measuring cell includes a cuvette and a sensing element, the sensing element including at least one radiation source and at least one detector configured to generate measurement signals, a control and evaluation unit that is connected to the sensing element to receive and process measurement signals of the sensing element, and a delivery and metering unit that can be controlled by the control and evaluation unit, where the control and evaluation unit is configured to control the delivery and metering unit to transport measuring fluid into the cuvette and to monitor the transport of the measuring fluid into the cuvette by means of the sensing element.

Automatic analyzer and method

An analytical device for determining a parameter of a liquid sample, especially a digestion parameter, such as chemical oxygen demand, total carbon content or total nitrogen content, comprising a reactor, and measuring system for ascertaining the parameter of the liquid sample. A container system for storing samples, reagents and waste products in containers, a transport and dosing system for metering and transporting the sample and reagents from the containers into a metering container and for disposal of waste products from the metering container into a waste container, and a measuring transducer for registering a measured parameter correlating, measured value of the liquid sample mixed in the reactor, and measuring, system, in given cases, with one or more reagents is provided. The transport and dosing system is embodied at least of a metering container, a piston pump and an additional sample taking apparatus at least for removal from a sample taking location of a predetermined volume of a liquid as a liquid sample.

Analytical device for determining a digestion parameter of a liquid sample

An analytical device for automated determining of a measured variable of a liquid sample, includes: a base module; a replaceable cassette connectable with the base module and having at least one liquid container connectable via a fluid line with a measuring cell and containing a reagent to be added to the liquid sample for forming a measured liquid; and a measuring transducer for registering measured values correlated with the measured variable for the measured liquid accommodated in the measuring cell. The cassette has, associated with the at least one liquid container, a fluid coupling apparatus having a primary component and a secondary component and serving for producing a connection of the fluid line with the liquid container.

Analytical device with base module and exchangeable cassette

A method for removing chloride from samples containing volatile organic carbon, wherein a chloride containing sample is mixed with a difficulty volatile acid, wherein hydrochloric acid gas arises, which is present in dissolved form in a sample-acid mixture and then the hydrochloric acid gas is purged by a carrier gas from the sample-acid mixture, wherein the hydrochloric acid gas is removed from the carrier gas following the purging and the carrier gas is fed back to the sample-acid mixture. In order during the hydrochloric acid purging largely to suppress the driving out of easily volatile organic compounds, the sample-acid mixture has a temperature of approximately 3&#xb0; C. to 30&#xb0; C., wherein, following the purging from the sample-acid mixture, the hydrochloric acid gas is removed from the carrier gas by absorption with water.
