NOVELTY - A high throughput system comprises 24 clear or translucent containers (tubes) for compounds in holes in a thermally conductive aluminum block and a lifting mechanism comprising a pin inserted in the bottom opening of the holes to partially push the containers out.    USE - System is for studying compounds and compositions and carrying out a salt forming, crystallisation or precipitation experiment.    ADVANTAGE - System provides high sensitivity and specificity and enables effective screening at low cost.    DETAILED DESCRIPTION - A high throughput system comprises 24 clear or translucent containers (tubes) for compounds in holes in a thermally conductive aluminum block and a lifting mechanism comprising a pin inserted in the bottom opening of the holes to partially push the containers out. There is an environmental control enclosure, robotic block movement system and the compound of interest is an active pharmaceutical ingredient with an additional solvent or excipient.    INDEPENDENT CLAIMS are also included for the following:    (1) a method of obtaining a compound of interest;    (2) a method of evaluating experiments;    (3) a method of screening a sample array comprises obtaining a Raman spectrum of each sample and determining which, if any, of the spectra share a spectral feature;    (4) a method of screening an array of samples for the presence of a particular form of a compound-of-interest, which comprises obtaining a Raman spectrum of each sample;    (5) a method of screening an array of samples for the absence of a particular form of a compound-of-interest, which comprises obtaining a Raman spectrum of each sample;    (6) a system for detecting similarities among various samples, comprises a device for obtaining a spectrum for each sample, and a computer configured to analyze each of the spectra and to generate bins, where each bin corresponds to samples sharing at least one spectral feature;    (7) a method of detecting similarities in samples; and    (8) a database containing spectral samples organized into bins, the bins corresponding to a hierarchical organization of the of spectral samples based on pair-wise similarity scores calculated in accordance with a similarity metric.    DESCRIPTION OF DRAWING(S) - The figure shows tubes filled with the compound of interest being processed and inspected.
