Problem
Possible Cause(s)
Corrective Action
Results
erroneously
high
Corrections may not have
been made for the reagent
blank.
Aspirate a blank and rerun standards and
samples.
Standard solutions may have
deteriorated or may have been
improperly made.
Restandardize with a proven standard.
Background emission may be
present.
Use background correction.
Results
erroneously
low
Standard solutions may have
been improperly made.
Rerun proven standards.
Blank solution may be
contaminated or not matrix-
matched to the standards.
Remake the blank solution. Acidify the blank
if the sample matrix is acidified.
Does the matrix composition
of the samples vary from that
of the blanks and standards?
If possible, prepare the standard and blank in
the same acid matrix used for the samples.
Or, internal standardization may be required.
Is the concentration for the
second standard lower than
that for the first?
Increase the Read Delay to flush the sample
introduction system completely.
Alternatively, aspirate a blank between
standards.
Is background correction
being used?
Check the placement of background
correction points. Refer to the Syngistix
Software Guide on the Syngistix Document

.
Are you analyzing aluminum
at 167 nm?
Run a high nitrogen purge continuously.
