Increase sensitivity of fluorescence measurements
Increase sensitivity of fluorescence measurements
The SX LED Light Source Upgrade provides a significant improvement in performance of stopped-flow fluorescence measurements. The higher intensity and stability of the LEDs compared to the existing xenon light source increases signal:noise and detection sensitivity limits.
Comparison of LEDs and xenon light source intensity
The LED Light Source comprises a power supply and one or more of a selection of wavelength-specific LEDs covering the UV and visible region (280-760nm). The LED connects directly to the cell block of the sample handling unit in place of the fiber-optic light guide from the xenon light source and monochromator.
Increase detection sensitivity and efficiency
Direct mounting of a new photodiode array detector to the cell block of the sample handling unit eliminates the need for a fiber-optic link between the cell and detector and improves overall light efficiency and sensitivity:
The figure shows a comparison of xenon lamp voltage output under identical conditions when using the old fiber optic and new direct-mount PDA accessories.
“The direct mount PDA upgrade from Applied Photophysics allowed me to upgrade my existing PDA to the latest specification. The upgraded PDA is really simple to fit to the instrument, has given me a ten-fold increase in sensitivity and has greatly improved the signal to noise ratio of my enzyme measurements.” -Dr Andy Holt, University of Alberta.
Compatible with all diode array models supplied to SX systems dating back to 1990. The existing Zeiss spectrometer unit from the original housing is transferred to the updated unit containing the latest control electronics and coupling optics.
Some older models may require upgrading to Pro-Data Windows based software.
Achieve modern performance standards
The SX Pro-Data Upgrade is a comprehensive electronics and Windows-based software upgrade to bring earlier generations of SX systems up to the standards expected from a modern SX20 system.
Instrument control is replaced with the latest Pro-Data electronics platform including a USB interface for Windows-based PC operation to provide a powerful, user friendly instrument interface for control, acquisition, display and data analysis. Dual channel detection is standard and an increased oversampling capability over logarithmic and linear time scales enhances data quality.
Extend the life of your instrument - this upgrade is compatible with all SF, DX and SX models of stopped-flow instruments supplied since 1990.
Compatibility with Windows 7 upwards
This USB communications upgrade replaces older fiber-optic communications on SX instruments supplied between 2004 and 2010 operating under Windows XP. All systems installed post-2010 feature USB communications and higher versions of Windows.
In addition to faster, more reliable communication, systems are ‘future-proofed’ for further software updates and compatibility with new accessories.
