Microliter syringes
Samples are supplied with microliter syringes. The injection volume is 50 to 500 µl. Op-
timum measurement results are reached when 50 to 100 % of the volume of the micro-
liter syringe is used. Various syringes are available. The canulas can be replaced.
For the analysis of particulate samples, the use of canulas with a larger inside diameter
(particle canula) is recommended.
Special microliter syringes with special geometry and a gas connection for NPOC analy-
ses are used for the autosamplers. The syringes have no graduation and are therefore
not suitable for manual operation.
