Table 1. Results of suspended matter concentrations (mg/l) collected using filter holders from the WTS-Tr instrument with the internal top frit in place and removed. Results from the standard laboratory millipore filtration system were used as a control.

The coefficient of variation is the standard deviation expressed as a percentage of the mean.
