Cleaning the Sample Windows
Thermo Scientific
Make sure the sample windows are clean before taking reference and sample measurements
with the instrument, and especially before you run the instrument performance tests or
perform any maintenance steps. The instrument has two windows that must be cleaned. One
is inside the sample cup where you load samples. The other is on the sampling arm.
