Title: Methods and compositions for improving the loading of analytical instruments

Abstract: The invention relates to improved methods and compositions for loading samples into an analytical instrument having a plurality of sample receiving loading ports. In a principle embodiment of the invention, first and second sample markers are added to sample to be loaded onto an analytical instrument having a plurality of sample receiving loading ports. The first and second samples are compounds are selected so as to produce a distinctive signal upon combination thus a sample containing a first sample marker and a sample containing a second marker are mistakenly loaded into the same sample receiving loading port, a detectable signal indicative of the misloading is produced.
