and the ability of the system to automatically carry out TC TIC &
NPOC analysis at a variable frequency, when necessary, using
the programmable TC CHECK STREAM 1-3 concentration level,
allows the user to be able to measure multiple parameters of the
sample to detect and identify process problems, without
increasing the typical analysis cycle time significantly.

the streams with AUTO range change function, please contact
your local distributor or the manufacturer. When AUTO range
change function is used, a minimum of five analysis reactions is
recommended as BioTector needs to find the optimum operation
range automatically. Therefore, depending on the system
response, it may be necessary to discard the first two or three
analysis results, when the AUTO range change function is
selected for a specific stream.
