9.1 The UV Light Path
The UV light path of the 6400EH is similar to that of the 6400E
(see Section 10.2 of the 6400E Manual). The main differences between
the 6400EH and the 6400E are:
 The location of the reference detector (See Section 9.1.1 of this
addendum).
 The methods used to reject for certain measurement interferents is
different (see Section 9.1.2 of this manual).
