The present invention provides a system, method and apparatus for identifying a product through reading of the product label by a retail terminal. The conductive passages are formed via discontinuities in 2DEG and 2DHG structure. Symbol synchronization is performed in the frequency domain by performing correlation between frequency components of the received signal and frequency-domain synchronization symbol. This design creates low backpressure with high liquid flow, which is suitable for the nanoflowUPLC application. The system comprises attachment devices and a body clamp and core extender and compressor, a housing, a spring loaded collar, a sensor core and a measuring unit.
