NOTE: ERBA XL 640 shows interference with iron assay when run randomly. Generally first sample in a batch also shows positive interferance. To prevent interferance, run iron and TIBC assay in saperate batch atleast once a day. This also helps in using fresh R1 with vitamin C. Program blank in Erba-XL 640. Program two types of Iron: 1) IRON 2) TIRON.
Iron batch
TIRON as first sample
Iron as subsequent samples
The equipment will take 3 TIRON blan, followed by 3 IRON blank. This TIRON will wash probe before measuring IRON.
