With no knobs to tweak and no optics to align, the XL is the perfect answer to most popular fluorescence applications. Each PI has his own unique directory for protocols and data storage, making it difficult to screw up someone else's flow data.
Samples run automatically after intial protocol setup.
All data are collected in list mode which permits subsequent analysis and gating. Listmode files are downloaded monthly onto Zip disks for storage. In addition, time can be used as a parameter which is essential for enzyme activity or calcium changes. Digitized signals are processed in real time by multiple Transputer microprocessors. 4 decade Log transformation and color compensation are performed by the Transputers on the linear digital signal.
