We based on ion trap for mass filter so that ultra-high vacuum is not needed to reduce the weight and size. We took frequency scanning to increase our mass range by 10,000,000,000. We used LED as LC detector to reduce size and cost. Therefore, we not only made a portable device but also a device with many special advantages in technology. An advanced analytical lab can become mobile to easily reach anywhere which needs in-situ and real-time analysis by our inventions.

We used LED as LC detector to reduce size and cost. Therefore, we have special advantages that include low volume, low cost, low weight, easy operation and in-situ real-time analysis.
Major applications for our portable LCMS include (1) drug detection (2) food safety assurance such as pesticide and Ractopamine detection (3) quality assurance of herb drugs (4) impurity detection for chip manufacturing (5) trace impurity detection (6) biomedical applications such as disease biomarker discovery. and (7) clinic diagnosis of illness.
