Summary form only given. A single-shot, trace oxygen monitor in the atmosphere above the bath section of a neat glass plant can substantially reduce glass defects and provide for improved glass production efficiency. Parts per million of oxygen can combine with tin to form tin oxide in a variety of ways and cause defects on the glass. A typical float glass plant produces 400-500 tons of glass a day. Present day measurement of oxygen concentration is estimated by taking samples of the atmosphere, which contains nitrogen and approximately 5% hydrogen, used to reduce oxygen to water, and contaminants, and analyzed off-line by measuring the dew point. This is a slow and inaccurate measurement that usually results in tons of defective glass being produced before corrective measures can be taken. Thus, rapid knowledge of the presence of oxygen leaks and the location of such leaks can provide timely information that result in substantial savings.
