Within the iTC200 software, activate the extended data mode by clicking the Extended Data Mode box in the Real Time Plot tab. While the software is in the extended data mode, the ITC data files will contain all available information produced by the iTC200. This additional information will often help the MicroCal technician diagnose problems. Software is then used to analyze the ITC data using fitting models to calculate reaction stoichiometry (n), binding constant (K D), enthalpy (ΔH) and entropy (ΔS).

These MCPM reference mod-ules can be added in field into either base. Software will automatically detect installed reference. Open reference door (See diagram 6): rotate the black knob counterclockwise and pull.

Summary
The MicroCal VP-ITC (Isothermal Titration Calorimeter) unit directly measures heat evolved or absorbed in liquid samples as a result of mixing precise amounts of reactants. A spinning syringe is utilized for injecting and mixing of reactants. The user inputs the experimental parameters (temperature, number of injections, injection volumes) and the computer carries out the experiment. Origin® software is then used to analyze the ITC data using fitting models to calculate reaction stoichiometry (n), binding constant (KD), enthalpy (ΔH) and entropy (ΔS).
To avoid damage or contamination, researchers must provide their own Hamilton 81414 syringe for loading sample solutions. The syringe can be purchased through VWR via CyBuy or directly from Hamilton. The instrument must be reserved in advance, and various rules apply. Reserve time using iLab. Reservations do not require approval.
The instrument is located in 1238 Hach Hall. Enquiries should be directed to Sarah Cady. Phone 515-294-5975 (office). NOTE: The Microcal ITC is now serviced and supported by the Malvern company.
