Abstract
A sample introduction system providing variable online dilution of a sample is described. In one or more implementations, the sample introduction system includes a sample pump configured to pump a sample in a specified time interval and a first carrier syringe pump configured to pump a volume of a carrier to be combined with the sample in the specified time interval. A control module is configured to receive a specified dilution level for the sample (e.g., input by an operator) and selectively adjust the volume of the carrier pumped by the first carrier syringe pump in the specified time interval to furnish the specified dilution for the sample.
