8.3.1 Analysis Mode
ANALYSIS TYPE TIC+TOC 
ANALYSIS TYPE defines BioTector’s analysis modes, which are
TIC+TOC (TIC&TOC), TC, TIC+TOCe and TCe.

When the analysis type is changed, the system automatically
modifies several system configuration parameters and resets
them to their default values. Therefore, when this function is
entered, before the analysis type is changed, system
automatically displays a “CAUTION! CHANGING ANALYSIS
TYPE ALTERS SYSTEM PARAMETERS AND REQUIRES
USER TO CHANGE SYSTEM CONFIGURATION SETTINGS.
PLEASE PRESS ESCAPE OR RIGHT ARROW TO PROCEED.”
warning to the user to inform the user about the changes
required in the system configuration settings.

Systems, which are built with two or more analysis type options,
are shipped with the relevant system configurations, which are
available in both electronic format and as printouts. When the
user changes the analysis type of the system, the necessary
system configuration modifications needs to be carried out
following the procedures described in information sheet “ M067.
BioTector Arm Configuration Upgrade Procedure ”, which is
available in the MMC/SD card shipped with the BioTector. When
the procedures are followed, the system configuration settings
will be updated automatically. Alternatively, all system
configuration modifications can be carried out manually by
looking at the corresponding configuration printout.
DEMO MODE
DEMO MODE OFF 
When DEMO MODE (OFF by default) is activated (ON), system
can be started to operate in demonstration mode. In this mode,
BioTector does not require any reagents or carrier gas to
operate. When BioTector is started using the Operation menus,
the relevant CO
2
peaks are generated artificially to demonstrate
the operation of the system. Because the system normal
operation is inhibited, system automatically displays a warning to
the user before the DEMO MODE is activated.
DEMO MODE CO2 DATA
TIC CURVE PEAK 1000ppm
TIC CURVE WIDTH 25s
TIC CURVE DELAY 2s
TOC CURVE WIDTH 3000ppm
TOC CURVE PEAK 55s
TOC CURVE DELAY 5s
TC CURVE WIDTH 4000ppm
TC CURVE PEAK 65s
TC CURVE DELAY 5s

The TIC/TOC/TC CURVE PEAK/WIDTH/DELAY functions in
Demo Mode CO2 Data menu allows the user to program the
size of the relevant CO
2
peaks, the duration of the CO
2
peaks
and the time delays artificially generated during the DEMO
MODE operation.

In TC and VOC systems, the relevant TIC/TOC/TC CURVE
PEAK/WIDTH/DELAY parameters are displayed.
