4.1 Data Table
4 - 4
(2) Detail Table
The repetitive measurement data of a selected element and
a selected sample can be displayed. A desired sample is
selectable by clicking the down arrow at the right of
[Sample ID].
When there are many repetitive measurement cycles, list
display can be scrolled by clicking the scroll bar at the right
of this table.
(3) Concentration
Table
The concentration values (corrected) of all measured
elements in unknown samples can be listed. The corrected
concentration is the post-correction concentration after
entering a concentration correction factor value (See
“Section 3, 3.1.7(6) Input for Correction on Concentration”).
Measurement result data may be accompanied with an error
mark.
Although measurement can be continued by ignoring an error
mark, data may lose reliability. It is therefore recommended to
take a corrective measure listed below.
Indication Cause Remedy
E Light intensity is 120 or
higher.
In manual measurement, execute auto-zero.
If lamp warm-up is not adequate in the autosampler
mode, this mark may be attached to data for some time
after start of measurement. In this case,
remeasurement is required.
If this mark still appears despite warm-up for 10 to 15
minutes or longer, deterioration or abnormal discharge
of the lamp can be thought. Check the lamp.
X Absorbance of STD2 to 10
is 0.001 or lower.
Make sure each standard sample has been prepared in
correct concentration and set at the specified cup
position.
When each standard sample is appropriate, make sure
the nozzle position of autosampler is adjusted properly
(if the nozzle position is too high, sample may not fall
into the cuvette). Also make sure each sample does
not scatter due to bumping in the drying/ashing stage,
ashing temperature is not extremely high and a
necessary matrix modifier is added.
L Concentration of unknown
sample is lower than
detection limit.
Check if a wrong sample was set.
