Unlike the chromatographic data processing software system on Windows 95/98, it is a true 32-bit chromatographic data processing application software system, highlighting many characteristics such as stable performance, accurate calculation, convenient operation, and personalized application. Suitable for data processing and control of various chromatography techniques such as gas chromatography, liquid chromatography, capillary electrophoresis, thin layer chromatography, supercritical fluid chromatography, etc.

Integrating the advantageous interface of N2000 chromatographic data workstation, the software adopts the mature core technology of our company's N2000 chromatographic data work, and embeds data tree structure management; Method correction reference guide, adopting a more user-friendly interface, without the need for tedious learning and training, can quickly master the use of software.

The hardware of N2010 chromatographic data processing software adopts advanced electronic design technology and high-performance components to manufacture a chromatographic data collector with high precision, low noise, high sampling frequency, low temperature drift, and can meet various analysis requirements, ensuring that the obtained chromatographic slice data is very close to the real spectrum. The resolution of the map is very high. This lays a solid foundation for subsequent data processing. She uses single channel, dual channel, and four channel working modes. Its main performance characteristics are:

The N2010 chromatographic data processing software is implemented using Microsoft's powerful programming language VISUAL Basic. She embodies many characteristics such as a simple interface, convenient operation, stable system, and accurate calculation results; And it has all the functions of domestic chromatographic data processing software. Its main performance characteristics are:

Software:

International standard Windows interface style; Multi threading and multi task parallel processing technology further improves stability. The spectrum window, spectrum file management window, and data result window are displayed simultaneously.

Foolish multi window integrated operation, avoiding back and forth interface switching, making work more convenient; Having a spectrum file management mode similar to a resource manager, the standard sample file, sample file, and method file are organically combined into a sample tree management system, which provides clearer operational ideas and greatly shortens the learning process.

There are various qualitative and quantitative methods to choose from, such as area, peak height and normalization, calibration normalization, external standard, internal standard, grouping, index, etc. Multiple manual baseline processing methods. Manual experience correction and computer automatic correction complement each other.

1. Integral algorithm: It can automatically distinguish various types of chromatographic peaks without missing peaks, making it easy to judge. The natural spectrum workstation can automatically and accurately integrate 90% of the spectra.

2. Good reproducibility: In terms of data processing software, a mature integration algorithm based on ten years of development and improvement of N2000 chromatography workstation ensures excellent reproducibility of integration results. Different peak discrimination parameters are used for multiple injection analyses of the same sample, with a retention time deviation of only 0.001 minutes. It can filter out noise without removing those small chromatographic peaks.

3. High precision: The data collector of this workstation adopts a full range non segmented method, with a full range accuracy of ± 1uV, and supports multiple sampling frequencies such as 40, 20, 10, and 5.

4. Equipped with data rollback function: When your computer crashes unexpectedly, the data collector can buffer and save spectral data for ten minutes. After restarting, the software can automatically restore the data, maximizing the protection of your labor results.

5. Easy to use and powerful: We use a database as support, which is very powerful in terms of processing, statistics, and analysis. Users can easily conduct repetitive analysis and print multiple parallel results on the same sheet of paper, which allows for statistical analysis of results over a period of time. Additionally, users can write their own extension applications. The user interface is based on the actual workflow of chromatographic analysis.

6. Wide compatibility: It adopts an external data processor with a high degree of integration, compact size, and advanced 24 bit CPU chip, and uses serial communication to completely solve the problem of some workstations being unable to install programs due to the lack of ISA cards on the computer. Can process signals from any chromatograph.

7. Serial port automatic detection setting, reducing installation setting parameters; Automatic processing of negative peaks, creating new samples and calibration guides, extremely convenient to use and operate;

Various spectral processing methods such as adding, subtracting, adjusting peak start and end points, adding or deleting segmentation lines, forcing trailing peaks, and setting negative peak areas greatly meet the requirements of personalized spectral processing. Various customization functions for analysis report forms; And it can be seamlessly linked to any text editing software (such as Office 2000) in the Windows environment, and the obtained spectra or data can be directly imported into a text editor, greatly improving the management and editing functions of spectra and data.
