calcium ions was prepared to mimic serum and wound fluid a known area of samples u2018 a eto u2019 u2018 a gamma u2019 u2018 a non sterile u2019 u2018 b eto u2019 b gamma u2032 and u2018 b non sterile u2019 was weighed dry weight and submerged in the test solution for 30 minutes the end weight wet weight was recorded and the absorbency potential was calculated retention post compression was also measured following submergence of a sample in the test solution as described above a weight representative of 40 mm mg pressure was applied to the sample for five minutes the retention of fluid in the sample was calculated a known area of each of samples u2018 c eto u2019 u2018 c gamma u2019 u2018 c non sterile u2019 u2018 d eto u2019 u2018 d gamma u2019 and u2018 d non sterile u2019 was weighed dry weight followed by submersion in the test solution over different time periods of 10 minutes 1 hour 24 hours 48 hours and 5 days the end weight wet weight was recorded and the absorbency potential calculated the results of test 1 are shown in table 3 and fig1 and 2 referring to fig1 it is apparent that the absorbency of sample u2018 a eto u2019 is higher than that of samples u2018 a gamma u2019 and u2018 a non sterile u2019 and the absorbency of sample b eto u2032 is higher than that of samples u2018 b gamma u2019 and u2018 b non sterile u2019 referring to fig2 it is apparent that the post compression fluid retention of sample u2018 a eto u2019 is higher than that of samples u2018 a gamma u2019 and u2018 a non sterile u2019 and the retention of sample b eto u2032 is higher.
