8.2 MetHoD SetUP
8.2.1 Selecting a Wavelength
The wavelength can be changed in the expanded
operating menu by using the keys adjacent to the
arrow icons. Use the keys to increase or decrease the
wavelength until the required wavelength has been
selected. The wavelength selected should be the same
wavelength that the standards and unknown samples are
to be measured at. The wavelength can also be adjusted
in the standard curve screen. Refer to section 8.2.3 for
more details.
8.2.2 Quantitation table
The quantitation table enables the quantitation standards to be viewed. This function also enables the
number of standards, units, resolution and operating mode to be set. To access the quantitation table
screen press the key adjacent to the
quantitation table icon in the expanded operating menu.
Only three standards can be displayed on the screen at
one time; to view the other standards in the table press
the key below the
down arrow icon. The quantitation
table displays the standard concentration on the left hand
side of the table with the corresponding absorbance or
% transmittance on the right hand side of the table. The
standard curve can also be accessed from this screen by
pressing the key adjacent to the
standard curve icon.
The standard curve can also be viewed from this screen
by pressing the key adjacent to the
standard curve icon.
8.2.2.1 Selecting number of Standards
The number of standards used to create a standard curve
can be changed from 2 to 6 standards. To change the
number of standards press the key below the
number
of standards icon. Repeat presses cycles the number
between 2, 3, 4, 5 and 6. If there is only one standard
available the concentration measurement mode should
be used.
8.2.2.2 Selecting Concentration Units
The units of concentration can be selected from a number of options: no units, %, ppm, EBC, SRM,
mEq/l, mEq, M, mM, µM, nM, U, U/l, U/ml, g/l, mg/l, µg/l, ng/l, g/dl, mg/dl, µg/dl, mg/ml, µg/ml, ng/ml,
µg/µl, ng/µl, mol/l, mmol/l.
In the quantitation table menu press the key below the
units icon and use the keys adjacent to the arrow icons
to navigate round the screen to select the required units.
Once the required units have been selected press the
key adjacent to the
tick icon to save and return to the
quantitation table screen.
