摘要： A method for determining a dosed, or metered, volume of an automatic peristaltic sample taker, in the case of which a measured, dosed, or metered, volume of the peristaltic sample taker is corrected by means of a calibration map.

摘要： A method for determining the number of drops metered with a drop frequency into a reactor, especially in a high temperature decomposition system for analyzers, wherein a gas stream is flowing through the reactor. There exists in the reactor a temperature, which is greater than the boiling temperature of the liquid, and a drop metered into the reactor transforms at least partially into the gas phase following entry into the reactor, especially due to heat transfer from contact with a surface within the reactor, especially directly after contact with the surface within the reactor. With a sampling rate, which is greater than the drop frequency, a sequence of pressure signals dependent on pressure within the reactor is registered, and, from the sequence of pressure signals or from values derived therefrom, the number of drops metered into the reactor is ascertained.
