ARKS RC - processing data of Reaction Calorimetry

The ARKS RC (Reaction Calorimetry Data Processing) software is the component of TSS-ARKS software and represents  the state-of-the-art program for thorough processing and analysis of data generated by reaction calorimeters of various types (Mettler RC1, Setaram DRC, HEL Simular, ChemiSens CPA 102, 202 and many others). ARKS RC offers the bunch of the most up-to-date methods for data processing. ARKS RC is an easy-to-use program thanks to the friendly self-guiding interface.

ARKS RC is addressed to the researchers that are involved in process design and thermal hazard assessment of chemical processes. It can be used as standalone software but the most beneficial way is to use this program as a part of the TSS-ARKS software

ARKS RC inherits the best features of its predecessor RCPro and has many new qualities - new interface, essentially reworked tools for data processing based on carefully improved algorithms, videotutorials to help in mastering software:

Loading data

The program allows a User to load, process, and store data of multi-response experiment (Temperature, heat generation, Pressure, species concentrations). Original data may be presented in integral or/and derivative (dT/dt, dP/dt) form. Data can be sampled with constant or variable rate.

ARKS RC is delivered in a package with the auxiliary Data Converter ARKS DConv program which allows easy and convenient way of converting data from ASCII format or from an Excel file  including concentration data. The possibility is foreseen to create a template for certain type of data which facilitates future work,

Storing data

ARKS RC provides storage of original and processed data into database which consists of data volumes (DV). Every DV includes number of data sets that represent results of separate runs. The unique feature of RCPro is that it uses the same database as  ARKS CK  software therefore no data transfer is required.

Processing data

The following types of data processing are supported by ARKS RC:

  • 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;
  • Linear transformation of responses;
  • thinning out data (decreasing number of data points without loss of information);
  • building complementary responses (derivatives from integral and vice versa);
  • correcting Pressure Response on Pressure of Inert Gas;
  • correcting the Pressure Response on Vapor Pressure; one can choose between Antoine and simplified August formulas for approximation of temperature dependency of vapor pressure;
  • calculating Gas Production responses;
  • reconstructing and correcting “under peak” base line; variety of linear and non-linear (curve, exponential, polynomial with variable order) base lines is supported;
  • integrating heat release rate peaks;
  • deconvoluting heat release rate data (compensation of dynamic distortions due to thermal inertia of a cell);
  • presenting data in graphic form in selectable axes;
  • presenting and viewing of 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;
  • Editing concentration responses (smoothing, spikes correction, cutting, linear transformation, thinning out)

To make data processing easier ARKS RC provides automated plot adjustment in accordance with processing type to be implemented.

Unique features of ARKS RC

  • when semi-batch data are processed the program takes into account variation of the mixture volume due to injection of reactants;
  • parameters of injections can be adjusted to properly synchronize injections and pulses of heat release rate;
  • estimation of energy accumulation in a semi-BATCH reactor which allows preliminary analysis of worst case scenario of cooling failure


The ARKS RC  is compatible with Windows  7, 8, 10, 11.

ARKS RC can be installed along any preferred path whereas ARKS DConv must be installed along the default path. Nevertheless we recommend to install both these programs along the default path (see below).


  1. The ARKS DConv setup should be downloaded and installed separately. Click here to download ARKS DConv
  2. ARKS TA, AC and RC use the same Data converter; therefore it should be installed only one time.  
  3. When installing ARKS RC under Windows 7 and higher we strongly recommend to use the default path C:\Users\[username]\CISP\ARKS RC
  4. When installing  TSS-ARKS applications one can meet the problem with Anti-virus tools you use. Some of them will recognize TSS-ARKS programs threats. Please don't worry. This happens because of new powerful protection system. TSS-ARKS software is now protected by the Enigma Protector - one of the world leaders in this area. To avoid the problem ask your IT service to exclude Users\[username]\CISP folder from virus  check.
  5. CISP guarantees that TSS-ARKS is 100% clean, which means its applications do not contain any form of malware, including but not limited to: spyware, viruses, tojans and back door.      

Requirements: Pentium V or higher, at least 512Mb of memory, 50Mb of hard disk space, Windows   7, 8, 10, 11

Be aware - even if you are the licensed user of RCPro after downloading and installing ARKS RC you will have to get new registration key. Please email us the request and don't forget to indicate your company and your name

IMPORTANT! Be aware that on the expiration of the Warranty/maintenance Period the License on any TSS or TSS-ARKS application remains valid for the version last updated during maintenance Period. Therefore if your maintenance has expired you wouldn't be able to use new updatesIf you nevertheless download the setup of new version and replace your working version with new one it won't work and you will lose working program! To avoid such situation check please whether you have valid maintenance before downloading any TSS-ARKS program.
