Modifications:

Version 1.3.12 released 25 August 2025

Fixed a small error when processing tails of positive peaks (phase transition, Joule effect calibration pulses, etc.).

Note: This version uses the same registration key as the previous version 1.3.11

Version 1.3.11 released 17 June 2024

Some inconveniences in the heat capacity determination and approximation procedures
were corrected. Specifically:
- now it is possible to calculate Cp using data previously corrected on the position of blank;
- coefficients of the approximation polynomial are determined in accordance with the temperature units chosen in the beginning f approximation.

Note: This version uses the same registration key as the previous version 1.3.10

Version 1.3.10 released 07 May 2024

1. The reworked algorithms for:
-  peaks integration;
-  analysis of data on phase transition;
-  determinantion of thermal conductivity.

2. Minor bugs fixed, the help system and Usersguide updated.

Note: This version requires new registration key.

Version 1.3.0.0 released 24 February 2024

1. Possibility to integrate separately DSC and dTG peaks when working with the combined DSC-TG data
2. Automated determination of the onset and outset temperatures when integrating peaks. Manual detection of the onset temperature for complex peaks is also supported.
3. Now 3 methods for determining glass transition parameters are available - based on the inflection point, half-height step method and new equal areas method deigned for analysing the cases when glass transition is overlapped with the enthalpy relaxation peak. In all the cases the glass transition height step (change of specific heat capacitty) is calculated
4. Added a function to correct the TG data to the position of the experimental baseline. This is especially necessary when using single-chamber thermobalance prone to zero level drift.
5. Minor bugs fixed, the help system and Usersguide updated.

Note: This version requires new registration key.

Version 1.2.71, released 12 November 2023

1. Fixed a bug that caused a problem when determining heat capacity.
2. Enhanced smoothing function in the Glass transition procedure.
Note: To install new version you should download and install previous verion ARKS TA 1.2.7 and then dowload here and run the patch to update to version 1.2.71

Version 1.2.71, released 12 November 2023

1. Fixed a bug that caused a problem when determining heat capacity.
2. Enhanced smoothing function in the Glass transition procedure.
Note: To install new version you should download and install previous verion ARKS TA 1.2.7 and then dowload here and run the patch to update to version 1.2.71

Version 1.2.70, released  15 October 2023

1. Significantly improved algorithms for processing phase transition data, a much more robust method for the
analysis of complex tails (case of 2-exponent relaxation mode).

2. An improved method for determining thermal conductivity coefficients. Using a new convergence criterion allows  more accurate determination of the coefficient

Version 1.2.5, released  03 October 2022

1. An improved method for calculating the heat capacity measured at linear heating has been added. It is based on averaging the values in a given temperature interval and allows  significant reduction of the influence of random noises on the results.. 

2. The updated data deconvolution method allows deconvolvution of certain fragments of the DSC curve, whereas in previous versions one could only deconvolve the entire DSC curve.

3. Improved method of creating an MS Word report. There may have been a problem with this option when using modern computers with high frequency multi-core processors (e.g. 3.2 GHz). The improved method avoids this problem.

Version 1.2.00, released  12 December 2021

1. New feature of this version is that it allows integration of DTG peaks. It is very useful when you process data of thermogravimetry. Peak intergration is specifically useful because you can determine the onset and outset temperatures in the same way as it was possible when integrating DSC peaks.

2. Numerous small improvements have been made to provide better stability of functioning and more accurate data processing.

Attention!

• Current users will have to get new registration key.
• New version ARKS DConv 1.0.31 is also available. There are some minor improvements in the code and documentation.

Version 1.1.10, released  15 September 2020

Further enhancement of the "Phase transition"  procedure. If the peak tail is complex, that is, relaxation of a crucible
(typically heavy high-pressure tight one) is described by the two-body model, then two time constants are determined.

Attention!

• Current users will have to get new registration key.
• New version ARKS DConv 1.0.03 is also available. We recommend to download and install it as well.

Version 1.1.00, released  15 April 2020

1. Essentially enhanced "Phase transition"  procedure:
- improved method for determination of the time constant even in the case of complex peak tails;
- additional method for thermal resistance determination from the slope of the peak front;
- automatic calculation of thermal resistance from the time constant
2. More convenient data presentation when working with Determination of  Glass transition  temperature

Version 1.0.01, released  31 July 2019

Minor bugs have been corrected

Version 1.0.0, released  01 May 2019

The first version of the program belonging to new software line TSS-ARKS
