4.6.4.1 Overview of Auto Addition
Auto Addition
Auto Addition withdraws specified volumes from common vials, then withdraws from a
sample vial. The common solutions and the sample are all contained in the sample loop
before injection. You can set a time delay for the injection of the sample and common
solutions.
Auto Addition is useful for applications requiring automatic addition of derivatizing agents,
standards, or reference peaks.
The Auto Addition table is saved in permanent memory.
Common Vials
You can specify up to five common vials for each Auto Run step. Common vials:
• Can be unique or repeated
• Do not have to be in consecutive positions in the carousel
• Can be different for each step
Auto Addition Sequence
During an Auto Addition run, the 717plus Autosampler:
• Withdraws from all common vials (specified on Auto Addition screen)
• Withdraws from the sample vial (specified on Auto Run screen)
• Delays, if specified
• Injects
