3.2 Automatic Continuous Measurement (6-cell auto mode)
3 - 60
3.2.3 Measuring DNA Sample (measurement through ratio calculation)
This instrument is capable of measuring the absorbance (at 230 nm, 260 nm, 280 nm and
320 nm) of a DNA sample and calculating the absorbance ratio (A260/A280 and A260/A230)
for check of the DNA purity. The instrument is also used for measuring the absorbance at 2
wavelengths and calculating the absorbance ratio or absorbance difference between the
values thus obtained.
Guide
: When auto start is specified, the system automatically
sets up the conditions and advances to the
measurement screen phase of sequence after the
power switch is turned on. For how to specify auto
start, refer to section 4.5..
