You can analyze water samples with your system. However, be cautious about
injecting seawater. It has been extensively found that high salt content
in water can affect the H and O isotope measurements (from laser analyzers
to IRMS techniques depending on the reactor/equilibration system). I can
share some papers offline if it is of your interest. Nonetheless, the salt
can cause issues with the syringe itself (i.e. Plunger start to get stuck,
blockage, etc) which will mess up the measurements at the end and increase
your maintenance and costs. On this matter, there is also plenty of
information and suggestions at the isogeochem archives to try to minimize
