7. Route the end of the P-trap drain tube to a suitable waste
fluid collection container. Be aware that as the tubing is
lowered, several mL of isopropyl alcohol will run out of the
tubing. This is normal and means that the P-trap is prop-
erly filled. Depending on your application, the P-trap fluid
may need periodic replenishment to ensure maximum sig-
nal strength of the ELSD.
Note
If accessible, the outlet end of the P-trap drain tube may be
used to refill the P-trap.
8. Route the attached tubing from the ELSD exhaust port
away from the system. This will prevent unnecessary sol-
vent vapor alarms.
Note
If using outside of the hood, ensure that the exhaust port tub-
ing is routed to an exhaust handling system that meets your
safety and environmental requirements. In normal operation,
the exhaust gas is dry and does not require a waste collection
container.
