Zusammenfassung
Inline filters on the QC8500
Antwort
No, we do not recommend the use of inline filters. The Lachat instrumentation is sensitive to time to valve, and if the filter were to become partially blocked or restricted it could affect results by not allowing the correct volume of sample to be injected into the instrument. We do recommend filtering the samples manually through a Whatman no. 42 filter paper in most methods, and would recommend verifying with your method procedure to see if a filter is applicable.
