When may it be better to use plastic instead of a glass sample cell in a Series 5000 Silica analyser?
Summary
Plastic vs glass sample cell in a Series 5000 Silica analyser
Answer
The plastic sample cell may be better to use than the glass sample cell in cases where the silica concentration is very low and readings are slightly high using a glass sample cell.  If the silica concentration is very low, there is a chance that silica from the glass cell may leach into the cell and be read during the test.
