Simultaneous Sampling Method of Sulfur Oxide and Gaseous Boron Compounds in Emission Gas using Type-1 Sampler (a Sampler Installed Inside of Stack)

Abstract

We have investigated a simultaneous collection method for sulfur oxide and gaseous boron compounds in the emission gas using a small inside stack sampler (type-1 stack sampler) with a quartz filter paper of 25 mm in diameter impregnated with 2 ∼ 10% sodium peroxide and 0.1 ∼ 1% Pt-Al₂O₃+5%K₂CO₃.
It was proved that the simultaneous measurement of sulfur oxide and gaseous boron compounds is possible under the following conditions with both filter papers: the flow rate is 0.5-2.0 L/min, the sulfur oxide is 0.2-2ppm, and the gaseous boron is 0.02-1.0 mg/m³.
