3.5   Options  
 
3.5.1 Calibration gas selector (optional) 

 
The AMA GC 5000 BTX can be equipped with two different calibration gas 
supplies. 
 
1.  Calibration gas generator: 
 

The analyzer is equipped with a communication interface to external 

 

gas generators.  

 
2.  Calibration gas cylinders: 

 

 

 

Fig. 4: Gas flow scheme of the calibration gas selector 

 
 
Optionally the analyzer can be equipped with a valve array for the selection 
of different sources of sampling. The array consists of 3 valves and can be 
used for one ambient source and two calibration sources. The needle 
valves of the calibration gas cylinders have to be adjusted to 70ml/min or 
more.  

 

 
3.5.2 Ozone precursor monitoring system (optional) 

 

For the on-line monitoring of hydrocarbons C2-C11 (ozone precursor) in 
one system, the AMA BTX analyzer can be synchronized with a AMA VOC 
analyzer. 
You have to select “Master mode on” in the BTX analyzer parameters and 
“Slave mode on” in the VOC analyzer parameters. Then each cycle and 
each calibration is started by the BTX analyzer.
