Ontech710 Ambient air VOC online detection GC

1. Deep cooling water removal, efficient enrichment:: Two stage cold trap enrichment, the lowest temperature can reach-30℃, and the concentration rate is greater than 1000:1. With the unique secondary focus design and unique water removal function, the polar compounds dissolved in the water are retained while removing the water in the sample, and the possibility of FID detector flameout can be avoided

2.  Injection volume: Use a mass flow controller to accurately control the injection volume, with an injection range of 5 to 2,000 ml.

3.  De-attachment analysis: adopting the unique patent stripping resolution technology, completely get rid of the traditional flash stripping resolution technology, so that low carbon compounds (C2-C6) can be perfectly separated, solve a worldwide problem, and won a number of patent certificates

4. Design features: adopting a chromatographic column, considering both C2-C12 all volatile organic compounds, using an instrument to achieve separation, solve the need for two instruments to detect high (C2-C6) and low (C6-C12) carbon compounds, compared to the "high carbon analyzer + low carbon analyzer" solution, it can greatly reduce the use cost for the user.

5. Highly integrated: Integrated pre-concentration and GC chromatography for automated site monitoring and online laboratory analysis.

6. Greater flux: Alternate sample injection,  collect the next sample while analyze the last sample , shorten the sample analysis period, and reduce the sampling blind area. And also can customize High-end double channel 4 cold trap, different channels alternately injection, so that the sampling without blind spot, truly seamless continuous sampling.

7.  Accurate and reliable： sample line inert process to avoid the cross contamination caused by high concentration of samples.

8.  Unattended operation：the system can automatically analyze the standard samples, run the calibration curve, save and export the data and other processes, and conduct regular operation and maintenance.

 9.  Simple operation： Summarize previous experience of system design, design from the user's point of view, make the system operation and analysis software simple and easy to use, suitable for operation and maintenance personnel to quickly start, sample reprocessing collects all the functions of the chromatography workstation, the application is flexible, convenient and fast.

10. Excessive warning-compound excessive warning function, can deliver the excessive situation to the mobile device, shorten the emergency response time.
