(4) Setup analytical conditions, standards table parameters,
and sample table parameters.

In emission measurement, it is recommended to use
resloping since variations in sensitivity are likely to occur
when a long time is taken for measurement.

For some elements, best results may be attained by
changing the default conditions.
(5) Verify the method.
(6) Supply cooling water.
(7) Ignite a flame.
(8) While injecting a standard solution having the highest
concentration of the analyte element, click the [Ready]
button.

In emission measurement, use the following reference
values of element concentrations in standard samples
for wavelength and intensity adjustments.
Alkali metals and alkaline earth metals:
Approx. 10 mg/L
Other elements:
Approx. 100 mg/L
(9) Check the [Lamp Spectrum].
(10) While injecting pure water, click the [Auto Zero] button.
The [Auto Zero] button on the spectrophotometer main unit
may also be used.
(11) Measure the sample concerned.

In emission measurement, it is recommended to use
resloping since variations in sensitivity are likely to occur
when a long time is taken for measurement.
(12) On completion of the measurement, turn off the flame and
stop the cooling water.
NOTE : Flame measurement does not use a hollow cathode
lamp. Therefore, any number may be set for the lamp
number.
