How can we determine the appropriate conditions for humidity controls during manufacturing?
Case Study 104PB
Let us consider Product A having the moisture uptake rate of
- 0.8 mg/min. at 43.2 %RH,
- 2.2 mg/min. at 75.3 %RH, and
- 3.0 mg/min. at 93.6 %RH.
What %RH control would be required to encapsulate Product A?
Based on the measurements we can extrapolate the maximum allowed humidity (i.e. 28 %RH at 0 mg/min. moisture uptake rate)
