FIA Background - def.- R & H define FIA as " A method based on injection of a liquid sample into a moving unsegmented continuous stream of a suitable liquid. The injected sample forms a zone, which is transported toward a detector that continuously records ... [some] physical parameter, as it continuously changes as a result of the passage of sample material through the flow cell." [R&H, 1st ed.]

some dye added with soda ash reflectance-based concentration predictions correlate well with FIA measurements (differences attributed to CCM calib done on Texomat dyeingsinstead of yarn pkg dyeing)
