software

The powerful software developed by the company can analyze the fingerprint spectra of trace volatile organic compounds in the test substance, which is simple, easy to use, intuitive and convenient. The software includes LAV software and qualitative analysis software.
Laboratoy Analytical Viewer (LAV) is used for data analysis and information extraction of gas-phase ion migration spectra. The software is compatible with data extraction programs on the Windows system, such as converting. MEA format to. CSV format and using the Windows system for data processing.
LAV software and related "plugins" have two main purposes:
Each signal peak in the gas-phase ion migration spectrum corresponds to the headspace component of the entire sample. The "Reporter" plugin installed in LAV software can compare the reference sample with the unknown sample to be tested, and users can easily see the differences in VOCs between samples at a glance.

The "Gallery plot" plugin is more intuitive for comparing the differences in VOCs in samples, and can be used to compare the presence or absence of various headspace components and the intensity of signal peaks in different samples, thereby identifying the similarity, authenticity, etc. of the samples.
This plugin plays a significant role in the traceability of gases and odors in the factory.

The LAV software includes classic quantitative analysis methods for measuring the concentration of individual volatile organic compounds. After establishing a standard curve using known compounds, the substance in the test sample can be quantitatively analyzed.

Quantitative Analysis in LAV Software

After establishing the standard curve, it is built into the instrument, and the instrument automatically displays the detection results after the detection process is completed.

Accurate and convenient qualitative software

The GC × IMS Library Search software can quickly and easily qualitatively identify unknown volatile organic compounds (VOCs) in the test substance. The software has built-in NIST gas phase retention index database and G.A.S. migration time database, which combine to make the qualitative analysis of compounds more accurate.

The GC × IMS Library Edit software can continuously supplement and expand the migration time database, and users can establish their own industry database to guide the development of their industry.

Application examples

Online process detection of VOCs in car cabin

The GC-IMS environmental gas analyzer can automatically analyze benzene derivatives and aldehydes and ketones in one go. The instrument is equipped with a Micro TD to achieve online rapid detection of seven national standard restricted VOCs (benzene, toluene, ethylbenzene, xylene, styrene, acetaldehyde, acrolein) in the car cabin. The entire analysis time can be optimized to 15 minutes, and the detection limit is as low as 2ppb.

3. Sampling head
4. Sample transfer tube
5. Gas phase ion mobility spectrometer

Online monitoring of VOCs changes during wastewater treatment process, using VOCs fingerprint spectrum to analyze the changes in the types and contents of volatile organic compounds in each step of wastewater treatment process, thus determining whether the water treatment equipment for that step is effective.

Factory odor traceability

Collect exhaust gases from each workshop online and obtain their VOCs fingerprint spectra. The left image shows the fingerprint spectra of the factory boundary gas and workshop exhaust gas. The bottom two samples are the factory boundary gas. It is easy to find the source of VOCs from the fingerprint spectrum comparison, and even accurate to the specific workshop, thus solving the problem of odor traceability.

To monitor the effectiveness of air purifiers in removing benzene derivatives, benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, and styrene were added to the environmental chamber. After turning on the air purifier, samples were taken every 20 minutes for on-site online testing. After the test was completed, the results were directly displayed on the instrument screen.
