An inside stack sampler (type-1 stack sample), which is not significantly influenced by the partial pressure and the temperature difference between the inside and outside of the flue, has been developed for the measurement of sublimable boron compound gas. An alkaline solution (potassium carbonate) impregnation filter paper was used as the absorbent. However, the previously developed outside stack sampler with collection bottles (type-2 stack sampler) was susceptible to both the partial pressure and the temperature difference for the measurement of sublimable compounds. Comparing both samplers, it can be concluded that the type-1 stack sampler is superior to the typ-2 because the former is not influenced by sublimation due to the inside stack sampling.
