OUR ADVANTAGES



1. What is the core technology behind MiTAP ?

MiTAP relies on gas chromatography (GC) technology to perform quantitative and qualitative sample analysis.

2. What kind of sensors are used ?

The system is designed with an internal sensor array. Sensor configurations can be customized according to the target VOCs specified by the client.

3. What is “micro-GC” ?

Micro-GC is Tricorntech’s patented technology for miniaturizing laboratory equipment (such as GC-MS) into portable and cost-effective systems.

4. Is MiTAP able to detect ozone precursors ?

Yes.

5. Can the MiTAP IAQ series detect the same TVOCs regulated by the government ?

Yes. The system is designed to measure the 12 different types of VOCs and TVOCs regulated by the Taiwanese government.

6. Can the system perform quantitative and qualitative analysis on mixtures such as gasoline or diesel ?

Yes.

7. How many different VOCs can be monitored by one MiTAP VOC analyzer ?

Each system can be customized according to client specifications. As for the model that is commercially available, 16 different VOCs can be analyzed qualitatively and quantitatively at once.

8. What is the system’s range of detected concentration ?

MiTAP offers a limit of detection (LoD) of less than 1 ppb, but the actual values will vary depending on the VOC. Take toluene as an example, its limit of detection can be less than 0.1 ppb.

9. What is MiTAP's detection capability ?

The system’s limit of detection is less than 1 ppb, but the actual values will vary depending on the VOC.

10. How long can the cylinder containing N2 carrier gas last ?

It can vary depending on usage conditions. Using the MiTAP S500 as an example, a 2-liter N2 cylinder can last a month when taking measurements at 30-minute cycles.

11. Are there any requirements or specifications for the N2 cylinder ?

There are no additional requirements aside from the purity of the N2 gas must be greater than or equal to 99.999% (5N).

12. What is MiTAP’s ideal operating temperature range ?

The suggested temperature range is between 20 and 30˚C (range may vary based on customer requirements).

13. Does the MiTAP VOC analyzer have any product certifications ?

MiTAP has received the CE marking.

14. Can I power the system with a UPS? How long will it last ?

Yes. A small UPS (2000VA) can power the system for approximately 3 hours.

15. Can the system detect non-target VOCs ?

The MiTAP F8 is capable of detecting non-target VOCs through semiquantitation.

16. What is the manifold system ?

The manifold system is a fixed online monitoring station capable of collecting air samples continuously from 2 to 32 different locations within a fixed area (~100 x 100m, but for semiconductor fabs, the maximum recommended space is 50 x 50m due to height considerations). Multiple MiTAP VOC analyzers can be placed inside a manifold system to enhance monitoring efficiency.

17. Can MiTAP detect at the PPM level ?

Yes. The system can be modified to take PPM or PPB measurements according to customer requirements.

18. Why are the TVOC concentration values measured by the F8 and the S500 different ?

The S500 shows the total of all target VOCs, and the F8 shows the total of all target as well as non-target VOCs.

19. How long should the lengths of the sampling pipes be for indoor and outdoor installation ?

The answer will vary based on client requirements. In general, PFA pipes are used in semiconductor fabs and the pipe lengths are between 100 and 200m. For outdoor applications, we will have to assess each environment separately in order to come up with the best configuration.
