Various applications and utilities

Correction Mode

Self correction for wavelength and cell holder position. Measured value for wavelength and cell holder position is compared with input correction data and then saved automatically.

Self diagnosis

By checking lamp and wavelength correction condition, get a more reliable data. By testing intensity of radiation at specific wavelength in ultraviolet and visible range, can confirm its condition is good or not.

Lamp Change Mode

Setup the wavelength for changing point between deuterium lamp and tungsten-halogen lamp in range in range 350nm to 470nm for measuring with the optimum intensity of radiation.

ABS/% T/CONC

Absorbance/transmittance/Concentration Measurement mode. Measuring one to ten samples for multi wavelength at a time. Saving measured method (Max 10). Concentration calculation with a standard curve or factor (Y=A*X+B; slope, B; intercept).

Survey Scan

Measure continuously absorbance/transmittance in 190nm~1100nm and confirm the data by Zoom in/out graphs in specific range. Search for Peaks and Valleys values automatically.

Standard Curve

Can measure by 7 Standard samples at a time and select one of 13 kinds concentration unit, Linear(N), Linear(O), Segmented Standard curve Types. Also can Make Standard Curve by inputting the maximum 30 of Concentration and Absorbance.

ABS Ratio

Can measure DNA/Protein by Numerator, Denominator, Reference measurement and factor. 260, 280, 230nm and correction wavelength(320nm) are setup basically to measure more easily.

Simple Kinetics

Measure continuously absorbance/transmittance variation at one wavelength during a certain period. Measuring interval is over 0.1 second and total measuring time is 99 hours in a maximum.
