Intended use of the instrument
Waters designed the 2475 Multi
λ
Fluorescence Detector to analyze samples
in high-performance liquid chromatography (HPLC) applications. The 2475
Multi
λ
Fluorescence detector is for research use only
Calibrating
To calibrate LC systems, follow acceptable calibration methods using at least
five standards to generate a standard curve. The concentration range for
standards should 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 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 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.
