
TC CHECK STREAM 1-3 determines the TC concentration
levels for each specific stream, above which the BioTector
carries out TC TIC & NPOC analysis cycles when the VOC
CYCLE above is programmed take place at a certain frequency,
which is greater than 1, as described above.

The BioTector operation with the programmable VOC CYCLE,
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.


If the CONTROL is programmed as BIOTECTOR, the multi-
stream valve sequence operates according to the STREAM and
RANGE settings defined in this menu.

In STREAM 1 , 2 setting, the first setting “1” represents the multi-
stream valve number (e.g. Stream Valve 1), and the second
setting “2” represents the number of reactions to be carried out
at this stream before switching to the next stream.

RANGE defines the operation range for each stream. In a multi-
stream system, the ranges are locked to Range 3 by default in
the factory. It is recommended to lock each stream to a
particular range (e.g. 1, 2 or 3), which is appropriate to the
concentration levels of the sample, in multi-stream systems.

When a specific stream is programmed as “- , - - -, RANGE -“,
the analysis on that stream does not take place.

The AUTO (AUTOMATIC) range change function is disabled in
multi-stream systems by default. If it is necessary to run any of
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.
