The serial number label is attached to the rear of each Agilent
Technologies instrument. This label has two instrument identification
entries. The first provides the instruments serial number and the second
provides the identification number for each option built into the
instrument.
The serial number is divided into two parts: the prefix (two letters and
the first four numbers), and the suffix (the last four numbers).
• The prefix letters indicate the country of manufacture. This code is
based on the ISO international country code standard, and is used to
designate the specific country of manufacture for the individual
product. The same product number could be manufactured in two
different countries. In this case the individual product serial numbers
would reflect different country of manufacture codes. The prefix also
consists of four numbers. This is a code identifying the date of the last
major design change.
• The suffix indicates an alpha numeric code which is used to ensure
unique identification of each product throughout Agilent Technologies.
