（GB/T 18883-2002）Indoor Air Quality Standards；

Detailed parameters:

Ø
1Complete testing eightspeciesVolatile organic compounds, for other unidentified peaks, the total content of all unknown peaks in the spectrum can also be calculated correctly according to national standards by automatically applying the working curve of toluene.

2、 AutomaticDeducting blank samples to calculate the true content of each component in the collected air sample，Use the ideal gas state equation to convert the content of each component in the air sample to the standard state.

IIIIt can calculate the content of each component and the total content of each component in the unit sampling volume, and can be converted to standard state.

4Calculate the total TVOC content in the sample under standard conditions using the TVOC version of the chromatographic data workstation.

5Multiple component detection can be performed simultaneously to complete the production of standard curves for eight controlled components in one go.

VIImpurity calculation function, which can quantitatively calculate unidentified peaks. *The manual qualitative function eliminates system qualitative errors.

7The preset working parameters for TVOC detection are convenient and easy to use. Support logarithmic calibration curve.

TVOC chromatography workstationTechnical Parameter：

1Sampling data can be read in from CDF files that comply with AIA (American Institute of Analysis) standards, which can be integrated with chromatographic workstations such as Angilent and Waters.
2. The range of the spectral display area can be adjusted freely, and it can be split left and right into two parts: global image and local magnified image. During the spectrum acquisition process, the full screen range of the spectrum display can be automatically adjusted.
3. During the spectrum acquisition process, spectra from two channels can be displayed simultaneously in the same window.
4. The zero point of the instrument signal can be set in the software.
5. Spectral peak intelligent identification technology greatly reduces the need for user set spectral processing parameters, and basically achieves automatic processing of peak detection, baseline correction, and overlapping peak segmentation. Automatically identify solvent peaks, tailing peaks, sawtooth peaks, and front and back shoulder peaks.
6. Automatically adjust parameters (peak width, slope) during the analysis process.
7. Baseline automatic tracking, automatic classification of chromatographic peak types; Peak rise and fall points.
8. The powerful manual integration function can achieve peak addition, peak deletion, peak merging, shoulder peak cutting, and specific baseline correction schemes (such as valley to valley baseline), and can also undo and restore manual processing of spectra.
9. The data results can be shared with software such as Microsoft Excel and Word; The data spectrum can be shared with image software such as Photoshop and CorelDRAW.
10. The data reanalysis function involves manually integrating and processing analysis results (with logs), classifying and archiving analysis data, and other functions.
11. Quantitative calculation methods: normalization method, calibration normalization method, internal standard method, grouping method, external standard method, index method.
12. It can calculate parameters such as baseline noise and drift, number of chromatography column trays, peak separation, tailing factor, capacity factor, etc.
13. It can create, delete, modify, query, sort and other spectral library management functions, and batch process spectral graphs.

TVOC chromatography workstationAfter years of improvement and upgrading, it has become the most stable and comprehensive chromatographic data workstation software in China Integrating management, analysis, and processing, it is suitable for complex analysis fields such as scientific research, commercial inspection, medicine, environment, and life sciences.
