TAKING MEASUREMENTS
4-1. Manual Measurement
(1)
Set the unknown sample in the measurement chamber.
(2)
Enter the Title of the run into the
①
Title Input Box
(3)
Tap the
②
Measure Button
to measure the unknown sample. “Out of range” is displayed for values
that fall outside the range of the standard curve. Although the application displays “Out of range,”
absorbance and intensity are displayed on the computer following CSV output.
(4)
With the initial setting, the measured valued (white) is displayed based on interpolation of the
standard curve between two points, but upon tapping the
③
Standard Curve Switch Buttons
,
display switches to the measurement value (green) based on the least squares fit line.
(5)
You can check the standard curve graph by tapping the
④
Standard Curve Graph Button
.
Measured values of unknown samples are plotted on the standard curve graph as open circles.
(6)
Tap the
⑤
CSV File Button
to output the data values to a CSV file
.

Units for the measurement value of the unknown sample can be selected from among three options
in the
⑥
Unit Selection Area
(Illustration 4-2).
・
Concentration (mg/mL in the figure below): The concentration is calculated from absorbance
based on the prepared standard curve.
・
RGB: This is the measurement value prior to conversion to absorbance.
・
ABS: This is the absorbance value prior to conversion to concentration.
