SAFETY SUMMARY
NOTICE precaution (Continued)
Accuracy and Precision of Measured Values
Carry out periodic inspection and check whether the system is operating normally.
If necessary, conduct measurement on a control sample.
Possible Carryover
When examining the results of measurements, take account of the possibility of occurrence
of a carryover. Otherwise, a correct judgment may not be formed. Since fluororesin and
quartz materials are used for the wetted parts of piping, particular attention should be paid
when analyzing samples that are likely to be adsorbed by these materials.
Before Turning on Xenon Lamp Again
After the xenon lamp is turned off, it remains very hot for a while. Under this condition, it is
not allowed to turn on the xenon lamp again for measurement.
Before turning on the xenon lamp again, wait for at least five minutes.
