Abstract
In the system for analyzing aqueous samples, the aqueous sample is deposited upon a sheet of filter paper which is held in a filter holder by clamping the peripheral edges of the filter paper between male and female threaded members of the filter holder. The filter paper with the sample is dried by a heated air stream directed perpendicularly toward the paper so that it flows around and through the paper. After the sample has been dried, it is analyzed by near infrared spectral analysis to measure the constituents of the dried sample.
