1. The equipment may not cause harmful interference.
2. The equipment must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications to this equipment not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. This equipment has been tested
and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at their expense. The following techniques can be used to reduce
interference problems:
1. Disconnect the equipment from its power source to verify that it is or is not the source of the
interference.
2. If the equipment is connected to the same outlet as the device experiencing interference, connect
the equipment to a different outlet.
3. Move the equipment away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the interference.
5. Try combinations of the above.
System overview
Chemical or biological hazards. If this instrument is used to monitor a treatment process and/or
chemical feed system for which there are regulatory limits and monitoring requirements related to
public health, public safety, food or beverage manufacture or processing, it is the responsibility of the
user of this instrument to know and abide by any applicable regulation and to have sufficient and
appropriate mechanisms in place for compliance with applicable regulations in the event of malfunction
of the instrument.
Fire hazard. The user is responsible to make sure that sufficient precautions are taken when the
equipment is used with methods that use flammable liquids. Make sure to obey correct user
precautions and safety protocols. This includes, but is not limited to, spill and leak controls, proper
ventilation, no unattended use, and that the instrument is never left unattended while power is applied.

The QuikChem
8500 Series 2 FIA (Flow Injection Analysis) System Unit is configured to complete a
flow injection analysis with a photometric detection. Alternate configurations, such as potentiometric
and amperometric detection methods are described in the analytical method where they are
necessary. For complete information on the software, refer to the online help system in the software.

• QuikChem
FIA System Unit—The System Unit includes the core unit and the sample processing
modules (SPM). The core unit supplies power, light and electronic signals to and from each SPM.
An SPM or a channel has an injection valve, a manifold, a photometric detector and a heating
module (optional). A System Unit can have up to five channels that operate simultaneously. A
single computer controls two System Units in order to operate up to eight channels at once. A
chemical reaction module or a manifold is installed on a channel for the quantitative analysis of an
analyte. There are 450 QuikChem methods available to find over 40 analytes. There are many
methods in several matrices.
• Sampler—The QuikChem
ASX-520 series autosamplers.
• Pump (12 or 16 cartridges)—The multichannel pump is used to pump reagents to the manifold. It
also aspirates sample aliquots and moves them from the sampler to the valve. These portions are
then loaded into the sample loop and moved to the manifold by the carrier stream to mix with the
reagents.
