PC-Control Software
The windows® based PC application soft-
ware takes the best features of the stand-
alone version plus more powerful data
processing and expanded data collecting
and storage capability. The software is
optional. Once it be used. the uv/v-l series
become more excellent
Quantitative:
Use up to 38 standards to establish standard curve. Four methods for fitting a curve: Linear fit, Linear through
zero, Square fit.
Kinetics:
The Kinetics mode may be used for time course scanning or reaction rate calculations. Abs. Vs. time graphs is
displayed on the screen in real time. Wail time, test time and time intervals may be set.
Wavelength Scan:
Automatically record peaks &
valleys. The quantity of the curves
is unlimited that you store.
Post- run manipulation &
processing includes: Re-scaling
axes, curve Smoothing,
combination, zooming, overlap...
1 st to 4th derivative.
Multi-wavelength Test:
You can set at
most 20 wavelengths to measure a sample.
DNA Test:
2 formulas are under your choice:
ONACon. =62.9 xA260 - 36.0 xA280
Features:
Large LCD Screen(128x64Dots)
!
The wavelength can be read out
from the screen directly
!
Auto zero & blank, easy to use. Press one button for
easy switching of Transmittance, Absorbance & Concentration modes
!
Parallel
port, data can be exported to printer directly
!
Coefficient method to measure the
uknown samples. C=kA+B. It can memorize the Last input of K & B
!
Large sample compartment, it can accommodate
5-100mm path length cuvettes with optional holders
!
Pre-aligned design ensures the user to change lamp conveniently
!
Optional software M.Wave Professional based on windows® can expand the applications to Standard Curve & Kinetics
!
High quality silicon photometric diode detector and 1200 lines/mm grating ensure the high accuracy and precision.
