Box Function
Used in wavescan only, this switches display of peak cursors on and off. Peak cursors show
vertical dashed lines displaying the measured peak height and horizontal dashed lines
showing the peak width.
Numeric entry. This is the duration over which a kinetic measurement is performed.
Used in CyDye DNA application only. This is the first dye type used in the measurement.
Used in CyDye DNA application only. This is the second dye type used in the measurement
(where applicable).
Numeric entry for CyDye DNA application only. This is the extinction coefficient of the
specified dye. Note for dyes included in the Ultrospec software these values are not editable
and the box will be greyed out.
Numeric entry to 3 decimal places. In concentration and nucleic acid measurements
multiplying absorbance readings by this factor gives the concentration value. In kinetic
measurements the result is calculated by multiplying this factor by absorbance, delta
absorbance or the slope.
Used in wavescan measurements only. This determines the sensitivity of the peak or valley
detection i.e. sensitive will detect more peaks or valleys than course. Options are; Off,
Coarse, Sensitive or Custom (when custom is selected the minimum peak height and width
must be entered).
Toggles between wavelength and absorbance, used in wavescan measurements only. This
determines how features will be ordered in the peak/valley table below the scan.
Toggles between peaks and valleys, used in wavescan measurements only. This determines
what feature type will be detected.
Used in User Access to set the group a user will belong to and what access they will be
granted.
Used in all applications. This is the duration the instrument will take a reading at an
individual wavelength. The longer the integration time, the greater the signal to noise ratio
and the greater the accuracy.
Numeric entry. This is the interval at which serial kinetics readings will be taken.
Used by the Ultrospec 8000 & 9000 in all applications to toggle between Precision and Pulse
mode.
Numeric entry. This is the upper limit of a wavescan measurement. Note that when using
the Ultrospec 7000/8000/9000 the max wavelength must always be greater than the min
wavelength by at least the step value.
Toggles between the kinetics measurement modes, serial and parallel.
Numeric entry. This is the lower limit of a wavescan measurement. Note that when using
the Ultrospec 7000/8000/9000 the max wavelength must always be greater than the min
wavelength by at least the step value.
Used in the Single Wavelength, Kinetics and Protein A280 applications to set the required
measurement mode.
Used in CyDye DNA application only, this sets the nucleic acid used in the measurement.
