11.2.1
Place pads straight from box into a Pyrex dish and combust
at 550
°
C in a muffle furnace for 1.5 hours.
11.2.2
Move pads to a 105
°
C oven for storage until ready to use.
11.2.3
Repeat steps 11.1.4 – 11.1.6.
11.2.4
After pads have come to room temperature, weigh pads

dishes for future use.
11.2.5
When ready to sample, place pad onto filtering apparatus.
11.2.6
Repeat steps 11.1.9 – 11.1.13 to calculate TSS value.
11.2.7
Once TSS value has been determined place pad into a
numbered porcelain crucible and record crucible number
and sample id.
