Patent ID: 7553669

Claim:
A method for monitoring reactivity in reactions between a first and second material of interest, said method comprising the steps of: a) providing an osmotic reaction detector comprising a semi-permeable membrane and a pressure sensor; b) introducing one of a reaction mixture and a reference solution into said osmotic reaction detector, said reaction mixture comprising a carrier fluid, a first material of interest and a second material of interest and said reference solution comprising any one or combination of the first material, the second material, a surrogate reference material and a carrier fluid; c) positioning said osmotic reaction detector such that said semi-permeable membrane is in fluid contact with and positioned between said reaction mixture and said reference solution; and d) monitoring an output from said pressure sensor after the positioning of said osmotic reaction detector, wherein any changes in pressure are measured in the reference solution and occur as a result of a change in concentration in said reaction mixture of one or more of said first material, second material, surrogate reference material or reaction products formed from said first and second materials.
