1.5.4 Sample Stream Precautions
The user is responsible to establish the potential hazard associated with each sample stream. Necessary
precautions must be taken, to avoid physical contact with any harmful sample stream, which may contain
chemical or biological hazards.
System components and their composition, which come in contact with the sample liquid and possible volatile
gases from the sample, are tabulated in table 1 below. If there are suspected compatibility issues between the
sample stream and BioTector components, please contact the manufacturer or the distributor.
