Which device best measures total suspended solids?

• A. Gooch Crucible
• B. Separatory Funnel
• C. Buchner Funnel
• D. Filter Funnel

Answer: (D)

Total suspended solids are determined by separating the solid particles from the water through filtration, then drying and weighing the captured solids. The device that directly performs this filtration by holding the filter paper and letting the sample drain through it is the filter funnel. It provides a simple, standard setup for collecting the suspended material on a filter so it can be dried and weighed to obtain the TSS value. Gooch crucibles are specialized for gravimetric analysis of certain precipitates and often involve ignition steps, which isn’t the typical routine for general TSS measurement. A separatory funnel is used for separating immiscible liquids, not for filtering solids from a suspension. A Buchner funnel offers faster filtration with vacuum, but the fundamental filtration step in standard TSS procedures is carried out with a filter funnel on a filter paper.
