Quality-Control; Ism Classification; Ism Classification: Ism Group 1 Class B - Waters ACQUITY UPLC I-Class System Manual

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. 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.

ISM classification

ISM Classification: ISM Group 1 Class B

This classification has been assigned in accordance with IEC CISPR 11
Industrial Scientific and Medical (ISM) instruments requirements. Group 1
products apply to intentionally generated and/or used conductively coupled
radio-frequency energy that is necessary for the internal functioning of the
equipment. Class B products are suitable for use in both commercial and
residential locations and can be directly connected to a low voltage,
power-supply network.
