Question
Is there a specification for total suspended solids (TSS) tolerance on a CL17 analyser sample?
Summary
CL17 and TSS tolerance.
Answer
The CL17 can take whatever comes through the 40 mesh filter in the sample conditioning kit. The main issue with elevated TSS levels is more frequent colorimeter (sample cell) cleaning, the frequency of which will be determined based on personal experience at the particular site.  Once the reference counts go too low and give a warning, it is time to clean the colorimeter.
