found to be as expected for both the milk and the fish data. It was found that up to c = 5 the list of polymers enriched by dropping some earlier ones and including new ones. However, for c≥6 a common subset of polymers appeared repeatedly as new polymers join in. This trend was found for both the milk and fish data though the polymers subset varied. In view of this c = 6 was taken for the optimal input for FCM. This optimal value for c seems to arise from the basic nature of data set generated by the LSER equation, Eq. (1),which is a linear sum of six independentterms. Tables 6 and 7 show the membership grades for all the polymers in the original list for the FCM analysis with c = 6. The highest membership grade polymers (shown in bold) are the selected polymers for sensors coating in the SAW sensor array. The selected polymers are separately summarized in Table 8 for both the milk and fish monitoring.
