•
Insert the sensor calibration tube provided with the SPE-Express unit (the tube should contain a
consistent column of DI water with a pH<2) and push the orange head of the capacitive sensor up
flush with the tube.
•
Ensure the sensor has power by entering into the Manual Screen and pressing the Sensor Power
Control below the graph.
•
Using a long pointed tool (such as a #1 screwdriver), press and hold the sensor “ON” button
(button closest to the back of the chamber). Confirm that the orange sensor indicator light is
blinking slowly. When the indicator light changes from slow blinking to a quick blinking
(approximately 6 sec) the ON state calibration is complete.
•
Remove the sensor calibration tube. Ensure that the water miscible waste tube is dry and re-
install the tube into the tube holder within the mount.
•
Push the orange sensor face onto the tube holder and tighten the sensor body nuts.
•
Using a long pointed tool (such as a #1 screwdriver) press and hold the sensor “OFF” button
(button is closest to the front of the station). Confirm that the sensor indicator light is blinking
slowly. When the indicator light changes from slow blinking to a quick blinking (approximately 6
sec) the OFF state calibration is complete.
•
Re-install the upper panel assembly by attaching the 4 wiring connectors (the color markings on
the connectors are the same for each pair of plug and receptacle to allow for easy matching of the
connectors and the wire numbers on either side of the plug and receptacle should also match).
•
Insert the female luer fittings of the water miscible waste and hexane waste tubes into the left
and right male luer fittings of the valve respectively. Tighten the fittings by turning the blue
portion counterclockwise.
•
Insert and tighten the nut of the eluted sample path from the bottom port of the valve into the
plug in the upper glass chamber. Re-install the 4 panel mount screws using a 5/64" Allen wrench.
5.6 Changing the Bottle Adapters and Injection Heads
The SPE-Express unit is supplied with 3 bottle adapters (one per station) which allow for the connection of the
53mm Wide Mouth Packer and 3 injection heads (one per station) which accept the 47mm filter assembly. Optional
adapters are available for the SPE-Express which accept a variety of bottles including the 33 mm Boston Round, 70
mm wide mouth jar and the 89 mm wide mouth jar. A larger injection head which adapts to the 90 mm filter
assembly is also an available optional accessory. The following gives instructions for changing these accessories.
•
Complete this step only if the injection head is being changed: remove the 2 screws on either side
and the 1 screw in the front of the front cover of the swinging assembly using a 3/32
"
Allen
wrench. Pull cover straight out from the unit, set cover and screws aside. Unscrew the 3 reagent
lines from the injection head and pull air intake tube off of the barb in the injection head (the
injection head may need to be turned in order to access these ports, the set screws will need to be
loosened prior to turning the injection head, this is explain in the next step).
•
There are 3 metal set screws located around the outside of the bottle adapter/ injection head to
prevent free spinning. Using a 3/32
"
Allen wrench, remove these set screws and set aside (if one
of the set screws is not easily accessible due to being blocked by the cover or assembly it will not
require loosening).
