Microfluidic ChipShop

PMMA and Topas commercial microchip (Microfluidic-ChipShop, Germany) with a 54-mm-long separation channel (between the running buffer, A, and the waste/detection, B, reservoirs) and 9-mm-long injection channel (between the sample, C, and the sample waste, D, reservoirs) is shown in Fig. 48.1. 

Microfluidic ChipShop (http //www.microfluidic-chipshop.com/) has also developed portable chip-based electrophoresis systems coupled with C D for on-site food analysis (ChipGenie edition E) [192]. Because contactless conductivity allows label-free detection, it is quite attractive to monitor the stability or the degradation products related to foodstuff. The portable instmment developed by microfluidic ChipShop comprises a box with dimensions of 190x 120x80mm (wxdxh). Basically, it consists of two parts, as shown in Figure 16.13, which are closed together and locked before running...
