When fitted with Waters options (APCI, APGC, APPI, ASAP, ESCi, NanoFlow ESI, TRIZAIC,
UniSpray, UPLC, ionKey), or optional third-party sources (DART, DESI, or LDTD), the Xevo TQ-
XS does not comply with the European Union In Vitro Diagnostic Device Directive 98/79/EC.
Calibrating
To calibrate LC systems, adopt acceptable calibration methods using at least five standards to
generate a standard curve. The concentration range for standards must include the entire range
of QC samples, typical specimens, and atypical specimens.
When calibrating mass spectrometers, consult the calibration section of the operator’s guide for
the instrument you are calibrating. In cases where an overview and maintenance guide, not an
operator’s guide, accompanies the instrument, consult the instrument’s online Help system for
calibration instructions.
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 these data until you are certain that the instrument performs satisfactorily.
