Does anyone on this list have experience with proper exhaust design for small scale digestion using 48% HF? The geochemistry researcher I am working with anticipates evaporating 2 liters of concentrated HF per month in a fume hood. I am interested in scrubbing technologies and if anyone has designed local exhaust systems that do not involve a fume hood. Thanks Joe Joseph R.
