摘要:

Organic compounds leached from paper and glass soxhlet thimbles have been identified by computerized high resolution gas chromatography /mass spectrometry. Nineteen specific organics have been tentatively identified from paper thimbles. The analysis of glass thimbles have not demonstrated these contaminants. The use of glass thimbles as a substitute for paper is advantageous in preparation of samples for trace organic analysis. This is an improvement but not a panacea as cross-contamination must still be evaluated by the analytical chemist.
