Carrier gas purity is critical for several reasons:
1. Catalyst Activity: Impurities in the carrier gas can poison the catalyst, reducing its activity and lifespan. For example, sulfur and chlorine compounds are notorious catalyst poisons. 2. Reaction Selectivity: Contaminants can also affect the selectivity of the catalytic reaction, leading to unwanted by-products. 3. Data Integrity: In analytical applications like gas chromatography, impure carrier gases can interfere with the detection and quantification of analytes, compromising the reliability of the data. 4. Safety: Certain impurities can be hazardous or reactive, posing safety risks in the laboratory or industrial settings.
