Before you begin
1.3 RFID technology
The Anatel PAT700 on-line TOC analyzer Onboard Automated Standards Introduction
System (OASIS™) employs Radio Frequency Identification (RFID) technology, a
registered radio frequency device. The RFID system in the PAT700 operates over a very
short distance to eliminate any interference with other wireless communications.
The term RFID describes a system that transmits data wirelessly using radio waves. An
RFID system is comprised of a “tag” and a “reader/writer”. In the PAT700 analyzer, the
tag is attached to the standards bottles used in calibrations (conductivity and TOC),
validations, system suitability tests, and excursion mode. The RFID tag consists of a
microchip attached to a radio antenna mounted on a substrate. The RFID tag is attached
to the bottom of the standards bottle. The microchip contains data about the standard
contained in the bottle. The PAT700 OASIS system contains four RFID reader/writers
permanently mounted inside the analyzer that align with the bottle RFID tags when the
bottles are fully loaded in the analyzer.
The reader/writer retrieves the data stored on the RFID tags located on the bottom of the
standards bottles. The RFID reader/writers have antennas that emit radio waves and
receive signals back from the tags on the standards bottles. The information provided
from the tag includes the identity of the standard, the standard’s concentration, date of
expiration and other pertinent data.
The reader/writer takes the data received from the tag and passes the information in
digital form to the PAT700 processor. The RFID system in the PAT700 can read and write
to the RFID tags attached to the standards bottle. The writing feature allows the PAT700
to write data to the bottles showing that the bottle has been used and provides for writing
of data for the exclusive excursion sampling feature.
The RFID system in the PAT700 does not require any user intervention to operate. The
system operates automatically when bottle tests are performed. The system
automatically turns on and off to read and write data only when necessary. When
enabled, the radio frequency modulation emitted from the antennas is fixed at 13.56 Mhz.
There are no user serviceable parts associated with the RFID system. The RFID
reader/writer board assembly should only be serviced by a HACH Company certified
service representative.
Since the RFID labels on the standards bottles contain the data necessary for each
standard, the labels must not be removed from the bottle. Without the label, the RFID
reader/writer has no data to read and will not operate as intended; however, bottles
without labels can be run if the user manually enters data.
