TDPro

Purpose of the program

The TDPro (Thermoanalytical Data Processing) software is the state-of-the-art program for thorough processing of data generated by various kinds of thermoanalytical instruments (differential scanning calorimetry, heat flux and isothermal calorimetry, thermal gravimetry, combined methods). TDPro offers the bunch of the most up-to-date methods for data processing including some original methods that are available only in this program. TDPro is an easy-to-use program thanks to the friendly self-guiding interface.

TDPro can be used as standalone software in physical-chemical laboratories that apply methods of thermal analysis but the most beneficial way is to use this program as a part of the TSS.

Loading data

The program allows a User to load, process, and store data of a multi response thermoanalytical experiment (DTA, DSC, TG, DSC+TG). Data can be sampled with constant or variable rate.

TDPro is delivered in a package with the auxiliary Text File Converter (TFC) program which allows easy and convenient way of converting data from ASCII format. The possibility is foreseen to create a template for certain type of data which facilitates future work,

Storing data

TDPro provides storage of original and processed data into internal database which consists of data volumes (DV). Every DV includes number of data sets that represent results of separate runs. Processed data can be saved directly into the ForK/DesK databases.

Processing data

The following types of data processing are supported by TDPro:

• Smoothing responses by applying exponential or polynomial filters;
• correcting pulse distortions (spikes) by applying linear cutter (replaces spike with the fragment of straight line), exponential corrector (replaces spike with the fragment of exponential curve), and polynomial corrector with variable order
• Cutting fragments including cutting tails, cutting internal fragments selected by 2 markers, deleting separate points marked by the cursor
• thinning out data (decreasing number of data points without loss of information);
• linear transformation of the responses
• subtracting experimental base line (blank)
• reconstructing and correcting “under peak” base line; variety of linear and non-linear (curve, exponential, polynomial with variable order) base lines is supported;
• building complementary responses (Q(t) based on DSC; DTG response based on TG);
• integrating DSC peaks;
• deconvoluting DSC data (compensation of dynamic distortions due to thermal inertia of a cell);
• presenting data in graphic form in selectable axes;
• Determining physical chemical properties

·         sample specific heat;

·         phase transition parameters (melting temperature and heat of fusion, etc);

• presenting and viewing several data sets simultaneously - Multigraph data presentation. This mode gives very convenient way to make the comparative analysis of results of several separate experiments including such cases when various calorimeters where used for the study of the same sample. All the data or chosen part of data sets can be transferred into the Excel just by selecting the corresponding menu option. The same Multigraph data presentation mode is used for statistical analysis of data.

Unique features of TDPro include:

• the procedure that allows reconstruction or the real sample temperature and estimation of sample overheating;
• the statistical analysis of results of parallel runs;
• the method for measuring thermal conductivity of liquid samples (by using C 80 Setaram instrument), no standards are required for calibration

Installation

The TDPro 2x and higher is compatible with Windows 2000/XP/VISTA/7.

The setup includes data converter capable of handling data of thermal analysis, adiabatic and reaction calorimetry. Installations of TDPro and TFC are implemented separately. Therefore the setup is an archive file. After extracting, you will get 2 sub-setups for installing TDPro and TFC. TDPro can be installed along any preferred path whereas TFC must be installed along the default path.

ATTENTION! When installing TDPro under Windows 7 the recommended path is C:\Users\[username

Requirements: Pentium V or higher, at least 256Mb of memory, 10Mb of hard disk space, Windows 2000, XP, VISTA, 7
