The blend of PVA with PEG- modified glucose oxidase could be used as glucose sensor characterized by the linearity of calibration curve in the range of concentration by 5 x 10"5 - 5 x 10"3 mol glucose L 1 [194],... 

Example g.l. Consider the two blending systems shown in Fig. 8.8. The flow rate or composition of stream 1 is the disturbance. The flow rate of stream 2 is the manipulated variable. In scheme A the sensor is located after the tank and therefore the... 

Fig. 3 Relative mass change with time of the QCM sensors featuring MIP-PMMA and NIP-PMMA blend films at 30 °C for sorhed vapours of (a) toluene and (b) 1,4-xylene. At zero time the toluene or 1,4-xylene vapour is passed and at the time of 60 min nitrogen gas is passed (1,1 ) 1,4-xylene-MIP-PMMA, (2, 2 ) toluene-MIP-PMMA, (5,5 ) NIP-PMMA (adapted from [113])...

It is clear that this method does not work in the case of a particulate medium/fluid mixture that saturates the sensor. In this way, we developed a second method that consists in filling the sensor with powder, measuring the blend... 

The entanglement generally reduces the leaching of active components from the matrix and so extends the operational lifetime of the ISE. However, PTC can also be blended with different amounts of vinyl chloride/vinyl acetate/vinyl alcohol copolymer (VAGH) which permits grafting of alkyl phosphate sensors and phosphonate mediators and 90 further reduces leaching effects.
