What is new in UniChrom ^(tm)

5.0.2.x UniChrom V 4d

• UniChrom 4d is not a new program, not an expensive option for program but a new way of working with GC,LC, GC/MS, LC/UV etc data in single framework.
• UniChrom n-VisiOn is going to share driver format with UniChrom 4d. For instance UV/VIS spectrometer working in n-Vsion would work as HPLC dtector in UniChrom V.

5.0.1.x UniChrom V

5.0.1.829

• New spectrum window displays GC/MS and LC/UV data for each sample point in chromatogram window.

5.0.1.525

• Internal data storage is in 8-byte IEEE float (double) representation (15 significant digits).
  Note: Files, saved by this version can be read only by this one version or later.
• Architecture revision for 64-bit compatibility
• The HP/Agilent Chemstation file converter now correctly detect sampling frequency for 3.x file versions.
• Included driver for PolyChrom ADC
• True X-platform built-in report generator
• The "Calculator" page (built-in spreadsheet with peak-oriented functions) now is printed as the part of report.
• Fixed several problems with "Info" page and modification flag
• Some configuration entries is stored in config files (.ini) instead of registry. This violates MS guidelines but improves compatibility and ease of migration for user settings.
• Default driver directory - UniChrom\drv, then all the others. Next step to install all drivers to this directory instead of windows\system(32).
• Lots of common code with n-VisiON
• Spectrum arithmetic take in account the layer shifts across X-axis. Layers for operations can be numbered absolute or relative to the layer being processed.

5.0.0.x UniChrom V

UniChrom had introduced new new concept. This make possible not only simplify user interface but increase the robustness of the entire system. Besides it made possible the UniChrom for Linux development. The 4.x program family uses the same file format - no changes. The changes are inside.

4.7.11 - codename "Red-Cat", September 2006

The version is intended as stabilising release. Contains tons of improvements and bugfixes.

4.7.11.677

• Developed the instrument driver for working with chromatographs "Crystall-5000.1", Crystall PM2 using the software control panel from Chromatec.
• Developed the common program interface for file converters both for Windows and Linux. AIA Net-CDF file converted successfully compiled under MS Visual Studio and GCC.
• Introduced the user authentication module (common for version 4 and V). Added the technical description chapter about activation the user-authentication system.
• Debug information from drivers and system state log are now written into text files located in UniChrom\log directory.
• Fixed problems of Configuration Editor with several registry hives work.
• International versions of UniChrom are translated in correct locale. Western-European symbols are now not lost.
• Developed the new user interface control - Table with unicode support, Clipboard copy/paste operations with formatting and HTML support. The control is used partially in UniChrom 4.x and almost everywhere in V and V-Linux.

4.7.10 codename "Tabby-Cat"

"Tabby Cat". The stripes are caused by moving all the system architecture to UniChrom V concept. The version is intended for parallel UniChrom 4 and UniChrom 5 development.

• Developed the support of Shimadzu-GC file format.
• Developed the new ADC - MSS-ADC. The driver supports capillary electrophoresis systems PrinceCE (www.princetechnologies.com), and also conductivity detectors TraceDec (www.istech.at)
• Started the migration if internal UniChrom structure to unicode support.
• Most of the UniChrom system modules made compatible with Linux compiler.
  Started the intensive UniChrom for Linux development.

4.7.x Codename "Black-Cat"

First presented at AnalyticaExpo-2005, April.

4.7.9.614

4.7.9.587

Significant rework of GUI interaction architecture. Get ready for UV/DAD and GC/MS applications.

• Released Shimadzu GC-2010 driver with ALS AOC-20 support.
• Released Thermo Trace-2000 driver w/o ALS support.
• Released Solar AP-2110 driver.

• Updated Crystall-2000M driver for support of new device: Crystall-5000.2
• New Configuration Editor provides modification of instrument configuration parameters in structured GUI dialogs with detailed Help System.
• It is possible to have tons of sample sequences in single file. Just start a desired sequence, then continue creation of new one, or alteration of old one. Each sequence has its own name. Each sequence can de run in whole, as partial sequence or a single sample from sequence.
• New file converter set. Has only interest to Russian users:
  • Internal file converter "ASCII file XY (*.xy)". Stores in ASCII-file not only signal values but the time like:
    ( xxxx.xxx yyy1.yyy yyy2.yyy yyy3.yy), where 1,2,3 - data of corresponding layers. xxx.xxx - time.
  • Chromatec Analytic file converter updated. Now it reads files of version 1.20, 1.21, 1.23, 1.24, 1.50.
  • Added reading of old E-Chrom data files (MiliChrom-5).
• Added new samples and specifications to UniChrom DDK / SDK package. External plugin can pass the file handle to UniChrom, to get the full binary method+data. It is usable for LIMS plugins. Added file converter specification, sample converter with sources.
• Theme improvements: XML tag describing control appearance can include the Delphi properties of control. For example: <controlname caption="Not a chromatogram" font.color=#ff00ff font.name="Bychkov Script"/>
• Added 3D Open GL chromatogram view. Not very important but nice pictures.

4.6.x Codename "Venus" released in June 2004

4.6.9.561 - Sep, 2004

Update release

• Written new ADC driver - Z-Chrom
• Reworked Crystall-5000 driver for compatibility with new firmware version.
• Reworked UniChrom identification assignments. Every identification method now assigns not only name but also other peak characteristics.
• Chromatogram batch can be split into several documents, and several different documents can be merged into the batch.
• Every data layer remembers the "Mode" of chromatographic device (either GC or LC) which was used for acquisition.

4.6.8.544 - Jul, 2004

• New style of HPLC controller form for all LC systems - Stayer, MiliChrom-5, MiliChrom-A02.
• Next release of MiliChrom-5 driver.
• First release of MiliChrom-A02 driver.
• Added UniChrom plug-in module manager (such as UniChrom-DHA), which allows to show all available modules, set it's parameters and start the module executuion.
• New Style of signal definition. For this purpose the new page prepared - "Signals". Signals define the channels prepared for measurement, the measuring layer parameters and even the layer colour. New measurement is prepared according to the signals table.
• The look and feel of calibration engine had changed. Now all the calibration tables are seen in single table with all information about calibration: response type - height or area, linear or logarithmic, type of interpolation, if the calibration is relative, all the interpolation coefficients with R-squared. The table can be easily copied to clipboard. The calibration graph is drawn immediately as the user selects the cell of the table.
• The relative calibration. Our implementation of internal standard method using absolute calibration. The analytic response is the ratio of responses of selected component and other, choosen as standard. If the calibration is relative, its state stored on disk and restored carefully.
• The calibration curve can be cubic (if suitable).
• The signal data can be easily integrated - the resulting curve is the time integral of inital curve.
• UniChrom supports user interface themes - change how the program look with the help XML encoded themes.
• The Configuration Editor now contains the GC instrument configuration dialog, which can help graphically configure the GC flow/pressure controllers.
• Added new window - Tools \ FlowCalc - the analogue of famous HP / Agilent flowcalc utility. Gas flow calculator for capillary columns with slightly different algorithms than HP product. Physical and chemical constants are taken from physical handbook written by A.Kikoin.
• Added several uncomman applications of UniChrom system.

4.5.8 Codename "Janus" released in January 2004

4.5.8.497 - Feb, 2004

• UniChrom help system is updated.
• UniChrom highlights in peak table the group of layers, measured simultaneously, when their channel numbers are in sequence.
• Running UniChrom with commandline switch -glp allows recording of data processing events in GLP log. The new page of spectrum window - "GLP" would show the events.
• Driver Crystall-5000 updated for correct TCD operation
• LabNET driver LnetC32.dll upgraded to version 1.0.0.4 with several fixes generally appeared in networking mode.

4.5.8.491 - Jan, 2004

• UniChrom supports of several "modes" for GC instrument. This allow easily switch between different methods which have similar data processing, but different chromatography conditions. The switching is done with single mouse click. Chromatography data layer remembers which GC mode was used for data acquisition
• UniChrom allows to draw the library (or calibration) chromatogram. Just create the new layer, add one peak manually, then select - "Processing - Smooth - Spectrum Normalisation". After this operation any added peak would allow editing all of peak parameters - position, height, area, asymmetry - you will get a line of ideal Gauss-shaped peaks according to entered parameters.
• UniChrom automatically creates data processing scenario (when there was not one). The scenario can be easily modified to correspond current analysis.
• Chromatogram data in UniChrom can be differentiated d/dt (see the "Smooth").
• The first driver version for "Crystall-5000" released . Driver supports all modes for capillary columns - programming of pressure, flow and carrier gas velocity.
• Significantly reworked "Crystall-2000M" driver for work with capillary columns in pressure, flow, velocity programming mode. Completely rewritten instrument detection.
• The ADC driver "E-24" is reworked for supporting E-24-clones, which are shipped with "Multichrom".
• Driver for ADC module "Aquilon"
• Driver for ADC module "LZI" reworked for support of automatic range switching.
• New UniChrom supports new file converters. Set of converters is reworked:
  Chromatec Analytic version 1.2x - provides different fileversions import.
  HP ChemStation - provides file import not only 4-th but from 3-rd version and higher (ADC,HPLC,GC data)
  Added new file converter "Tsvett-Chrom" 1.x
• Microcolumn HPLC system "Milichrom-5"
• UniChrom contains new instrumental manager, which categorises opened methods according their types and also instruments that have been used for measurements, and also allows easily navigate between methods and chromatograms. See the menu View/UniChrom.
• Added new driver for "Tsvett-800", which provides dynamic range extension mode even using standard instrument configuration.
