Ensuring carrier gas purity involves several strategies:
1. High-Purity Gas Sources: Purchasing gases from reputable suppliers who provide detailed certificates of analysis. 2. Gas Purifiers: Using inline purifiers and filters to remove residual impurities. These can include moisture traps, oxygen scrubbers, and hydrocarbon traps. 3. Regular Maintenance: Regularly checking and maintaining gas delivery systems to prevent contamination. 4. Leak Detection: Employing leak detection techniques to ensure that external contaminants do not enter the gas stream.
