1. However, some surface contamination will disrupt the laminar flow, making it turbulent. 2. An example of this is a scintillation detector used for surface contamination monitoring. 3. For heavier surface contamination or improved process speed, additional activators can be added. 4. It pioneered new methods to try to eliminate the risk of surface contamination . 5. However, if surface contamination is present, more attention is required. 6. This applies especially to pure metals produced in vacuum which suffer no surface contamination . 7. Substrates need to be clean and free from surface contamination to allow proper ink adhesion. 8. The new wing offers considerably better performance at high speeds and better immunity from surface contamination . 9. The canard, to reduce sensitivity to surface contamination . 10. Any surface contamination , notably the oil from human fingertips, can damage the quartz envelope when it is heated.
