We have machines called ‘galley filters’ here at work, and they are used to measure enzyme levels in areas where enzymes are used. Does anyone know how these work?
It would probably help if you told us what you do. :dubious: :rolleyes: :smack:
I think FlippyFly measures enzyme levels for a living. 
I didn’t think that was important. I am a supervisor at a plant where we make Wisk, All, and Snuggle laundry products. We have enzymes in Wisk detergent (but not in All or Snuggle). I work specifically in the liquid packing area of the plant (in contrast to the liquid making area). We have to run a galley filter anytime we run Wisk on a manufacturing line and take samples twice per shift. We also have to run the galley filters at all times in the enzyme room.
Everyone I have asked around here knows how to run the galley filters, but no one knows how they work.
Galley Sampler Only 10 hits, the machine must be pretty specific to the detergent industry.
The machine measures the concentration of protease dusts in the air. From the inadequate descriptions I found, the machine collects particulates from the air on a glass filter. After several hours of collection, the filter is extracted (?), and the extract subjected to a standard, probably colorimetric, protease assay.
