摘要

Time of Flight (ToF) secondary ion mass spectroscopy (SIMS) is a relatively new tecnique for probing the chemistry of surfaces. We have applied SIMS to a wide variety of papers and papermaking problems and found it to be a powerful tool for analysis and problem solving. A number of applications are discussed in detail with emphasis on problems involving defects and runnability. SIMS helped resolve a sizing problem in which we found pitch to be a highly effective desizing agent. This brings a new insight to an old problem - why some pulps are more difficult to size than others.
