摘要: This work presents a way of using silicon microfabrication to take advantage the rim wafer in novel manner. Our circular multichip platform, which is fabricated only standard techniques, has 60 identical miniaturized micropillar array electrospray ionization (μPESI) chips at periphery wafer. The platform fixed on computer controlled rotating table, front mass spectrometer (MS). After each MS measurement an unused μPESI chip aligned towards by programmable table. wafer-scale enabled samples 8 minutes. can also be stored for later analysis.
