DeCapita EGD-54-68 Subject Analysis of Room and Poly Air Samples From the Niagara Falls Plant The latest set of air samples you collected at the Niagara Falls Plant on 7-26-68 have been analysed by gas chromatography. The quantitative results are tabulated below. The analyses were made on 8-6-68. Previous analyses have indicated as much as a 10$ loss in monomer concentration in the sample tubes within 24 hours. If additional future work on this type of sample analysis is contemplated, I would recommend that sampling and analyses times be more closely coordinated.
