waste” laws also apply in other jurisdictions. In all cases, ensure that a certified electronics
recycler processes end-of-life instruments.

local laws governing their processing and safe disposal.
Applications: quality control
Routinely run three QC samples that represent subnormal, normal, and above-normal levels of a
compound. If sample trays are the same or very similar, vary the location of the QC samples in
the trays. Ensure that QC sample results fall within an acceptable range and evaluate precision
from day to day and run to run. Data collected when QC samples are out of range might not be
valid. Do not report this data until you are certain that the instrument performs satisfactorily.
Equipment misuse notice
