Note
It may be necessary to extend the drain tube. If so, splice the
tubing with user-supplied tubing. The user-supplied tubing
should have an inside diameter no smaller than the existing
drain tubing, and must be compatible with the solvents used by
the system. Route this extension tubing to the waste collection
vessel.
CombiFlash with optional ELSD only) The CombiFlash
ELSD system has additional drains that must be connected
(Figure 2-7):

4. Locate the
/
inch I.D. silicone tubing and a nylon tubing
4
clamp from the accessory kit. Connect one end of the tub-
ing to the pump drain port and secure it with the clamp.
5. Install the ELSD P-trap vent assembly found in the acces-
sory package by placing the short tube into the port on the
rear panel, orienting the vent as shown in Figure 2-7 and
tightening the fitting nut finger tight plus a small amount
more with a wrench. Be sure the P-trap drain vent assem-
bly is oriented with the vent portion vertical.
6. The P-trap must be filled with fluid to prevent sample loss.
To accomplish this, raise the drain tubing attached to the
P-trap drain vent assembly above the instrument and
place 10 mL of liquid, such as isopropyl alcohol, into the
tube. Make sure the fluid level in the tubing doesn't exceed
the level of the instrument case top. If the tubing is raised
too fast, fluid may flow out the top of the vent tube causing
a spill. Lift it high enough so the fluid enters the P-trap
drain (Figure 2-7).
