Seven thermo-labile organophosphorous pesticides, isocarbophos, monocrotophos, phospha-midon,methamidophos, acephate, phosmet and trichlorfon were determined by capillary gas chro-matography (GC) with FPD.
Residual stress exists in the PMMA microfludic chip due to the different thermal expansion coefficience,also called thermal mismatching of the mold and the polymer,which can result in the warpage and deformation of the chip.
