6. Quality Control
6.1
Introduction
CAUTION
IF AT ANY TIME THE ANALYTICAL PERFORMANCE OF THE
SUNRISE IS QUESTIONED THE USER SHOULD FOLLOW THE
INSTRUCTIONS GIVEN FOR QUALITY CONTROL OR CONTACT THE
LOCAL SERVICE CENTER.
CAUTION
BEFORE STARTING MEASUREMENTS, MAKE SURE THAT THE
MICROPLATE POSITION A1 IS INSERTED CORRECTLY.
This chapter gives the instructions on how to obtain the best performance and
accuracy from this instrument.
Also included are instructions on how to easily check the operational quality of
the instrument.
6.2
Optimizing for Maximum Performance
The instrument has been fully factory tested to ensure that its performance is
within the specified limits.
Experience has shown that operating technique and laboratory conditions cause
the greatest amount of inaccuracy.
The greatest accuracy can be obtained from the instrument by observing the
recommendations below:
6.2.1
Instrument Location
The instrument should be placed on a level, flat surface that is free from dust,
solvents and acidic vapors.
The instrument must be protected from vibrations and direct light, particularly
sunlight.
When performing the measurements, always close the plate support cover to
ensure that the results are not affected by any external light.
6.2.2
Operating Procedure
General
1. The best repeatability is obtained, when the measurement wavelength
corresponds to the maximum absorbance wavelength of the particular
solution.
It is important to use the maximum absorbance wavelength, if the absorbance
curve of the sample is over a narrow wavelength band.
2. After each microplate has been measured, please refer to the test kit package
for information regarding the validation procedure.
