Key Differences
Split Injection
Purpose: Designed for samples with high concentrations.
Mechanism: Only a portion of the sample enters the column, the rest is vented out.
Advantage: Prevents column overload and extends column life.
Splitless Injection
Purpose: Suitable for samples with low concentrations.
Mechanism: The entire sample is directed into the column.
Advantage: Maximizes sensitivity as more sample analyte reaches the detector.
Choosing the Right Method
Consider sample concentration when choosing between split and splitless.
Evaluate analysis sensitivity requirements to decide which method aligns with the analytical needs.
