2.2 SPECIAL SAMPLES
Note that Equations (1) and (2) indicated in APPENDIX 1 are not
valid in analyzing the following samples:
Fluorescing samples
Samples having high turbidity
In measurement of a solid sample such as glass plate, a loss (
r
) in
optical energy occurs due to reflection on the sample surface. In
this case, the following equation is valid.
