Can you tell me what is a good/optimum/typical flow rate of slurry feeding an OSA "on stream analyzer" adequately? I need to size and purchase my sample pump to feed the multiplexer. Thanks!

Some say a primary sampler should extract 100–200 l/min of sample stream from the process. Others say it should be between 60-300 l/min, with the optimum flow to the OSA is 150 liters/min or 40 US gallon per minute.

Here is a great set of videos explaining the best of sampling practices called:
