Installation guidelines
Amperometric detection is a highly sensitive technique because the currents measured are usually in
the picoampere or nanoampere range. Electrical disturbances in the environment have an effect on
operation. In addition, temperature has an effect on the response (and baseline drift) because
detection is a chemical reaction. The effect of temperature is easiest to see at high detector gain.
Install the amperometric detector:
• Indoors in a clean, dry, well-ventilated and temperature-controlled location.
• Away from direct sunlight and heat sources.
• Away from drafts, windows, refrigerators and air ducts.
• Away from radio-frequency (RF) interferences (e.g., wifi devices).
• In a location with minimum mechanical vibrations and electronic noise.
• In a location where there is sufficient clearance to make plumbing and electrical connections.
Connect the entire system to the same grounded power line to prevent electrical noise. Select a
power line that is not used by instruments that cause electrical noise in the power line (e.g., ovens,
mixers or motors).
If electro-static discharge (ESD) causes electrical interference, operate the detector in a static-safe
area with anti-static floor pads and work bench pads.
Install ferrites on the cables as necessary to prevent electrical noise.
Assemble the flow cell
N O T I C E
Two working electrodes are supplied. Use the silver working electrode (MF-1008). Do not use the carbon working
electrode (MF-1000).
Assemble the flow cell in the amperometric detector enclosure. Refer to Figure 5 to collect the parts
used. Refer to the illustrated steps that follow to assemble the flow cell.
Note: When installed, the working electrode jumper increases the size of the working electrode by two times, which
increases the signal.
