This monochromator based instrument uses a high energy pulsed Xenon source for excitation. For more than 20 years PerkinElmer has relied on pulsed Xenon sources to minimize photo bleaching of samples and provide a long-lived excitation source. FL WinLab™ software, designed for the demanding needs of modern laboratories, operates in the Microsoft® Windows® environment and controls the LS 45. The software combines the user-friendly appeal of a Windows based software package with application specific knowledge PerkinElmer has developed through decades of experience. The result is a powerful system that can be used routinely for quality fluorescence analyses. Specific modes of instrument operation such as Scan, Time Drive, and Ratio Data Collection can be easily accessed in the Application Menu. The excitation and emission monochromators can be scanned independently or synchronously. In addition, the PRESCAN mode is an ideal method development tool for location of peak excitation and emission maxima. FL WinLab includes a validation protocol that automatically checks the instrument performance to ensure that it is operating within specification. FL WinLab, when combined with the LS 45, provides a wealth of tools for data collection and analysis such as:
Accessories add sampling flexibility: The LS 45 includes a single cell thermostatted sample holder. The cell holder accommodates 1 cm pathlength cells as well as semi-micro cuvettes. Semi-micro cuvettes are particularly useful where the sample is precious or the volume is limited such as cell cultures and DNA samples. A variety of accessories are available for use with the LS 45. For example, our automated Polarizer consists of 2 filter wheels; each wheel containing a horizontal and vertical polarizing element. Polarizer positions are software controlled and can be manually set or automatically controlled for polarization, anisotropy or G-factor. Additional accessories include the following: Application figure window. Single cell thermostatted sample holder is included with the LS 45.
