Table 1. Potentiometric response of PVC membranes doped with TDMAC toward polyanion samples with different ratios of OSCS and porcine heparin a.
OSCS wt% in polyanion preparations | Avg. b | EMF (mV)SD (mV) c |
---|---|---|
100 | -78.8 | 2.2 |
20 | -78.8 | 1.3 |
10 | -78.2 | 1.8 |
1.0 | -74.7 | 1.5 |

. The final polyanion concentration is 1 mg/mL.
. EMF values were recorded 10 min after the injection of polyanion solutions
. The standard deviations were calculated using data collected from 4 sensors for each concentration.
