Device and method for measuring the heat of reaction resulting from mixture of a plurality of reagents

A method for measuring the heat of reaction resulting from the mixture of a plurality of liquid reagents comprising:

• filling a compartment with a first liquid reagent;
• providing a second liquid reagent into said compartment to cause a portion of said first liquid reagent to be displaced from said compartment;
• withdrawing a predetermined portion of the first and second reagents from the compartment after said portion of the first liquid reagent is displaced from said compartment;
• depositing the withdrawn predetermined portion of first and second reagents back into the compartment;
• generating electrical signals based on the heat of reaction resulting from mixture of the first and second reagents;
• and
• deriving data indicative of the heat of reaction based on said electrical signals.

A method for measuring the heat of reaction resulting from the mixture of a plurality of reagents comprising the steps of:

• initially providing a predetermined amount of first reagent into a compartment;
• then providing a predetermined amount of second reagent into said compartment to cause said first and second reagents to mix within said compartment;
• then providing an additional amount of said first reagent into the compartment in such fashion which causes the mixed reagents within the compartment to circulate in a substantially uniform direction within the compartment;
• generating electrical signals based on the heat of reaction of the mixed reagents within the compartmentp;
• and
• deriving data indicative of the heat of reaction based on said electrical signals.

A device for measuring the heat of reaction resulting from mixture of a plurality of reagents, comprising:

• a compartment;
• a first injection assembly for providing a first reagent into said compartment;
• a second injection assembly for providing a second reagent into said compartment to permit said first and second reagents to initially mix within said compartment,
• at least one of said first and second injection assemblies being constructed and arranged to be able to i) withdraw a predetermined portion of said first and second reagents from said compartment after the reagents have been initially mixed within said compartment and ii) deposit the withdrawn predetermined portion of said first and second reagents back into the compartment so as to facilitate stirring of said first and second reagents within said compartment;
• and
• a measuring apparatus operably connected with said compartment for deriving data indicative of the heat of reaction resulting from mixing said first and second reagents.
