Detection principle

Using rapid gas phase chromatography, ion migration spectroscopy and an organic matter database, VOCsmart® 2000 can quickly analyze volatile organic compounds in liquids, with a detection limit of 0.1ppb. Volatile organic compounds show the unique fingerprint (Fingerprint / pattern) of the test sample in a three-dimensional way. The software compares to the fingerprint with a variety of model analysis and the organic matter database in the cloud platform, so as to quickly quantify the volatile organic compounds in the liquid.

Data analysis and application of VOCsmart® 2000

Using the VOCsmart® 2000 analysis software designed by Epmonitor, it is easy to learn and icon-based in only a few steps

1) Measurement data: After collecting the IMS gas analysis of the sample, the IMS fingerprint map shows the components of different compounds contained in the sample.

2) After learning to manually select the main parameters from the map, using these parameters can be analyzed again to classify and identify the unknown samples

3) Prediction / classification: Under the prediction mode, the fingerprint library of different organic matter stored in the cloud platform can be used to compare, quickly analyze the type and concentration of samples, and qualitatively determine the sample source.
