4.3 Total Dissolved and Suspended Solids Dried at 103°C – 105°C
Procedure:
1. Heat evaporating dish to 550° C in muffle oven for 1 hr.
2. Remove and place dishes in air to cool.
3. Place dishes in desiccator and weigh the cooled dish before use.
4. Obtain and weigh filter paper from package
5. Place filter paper into the funnel assembly on the lab bench.
6. Obtain and mix well an unknown sample to obtain a more uniform participle size.
7. Pour 15 mL of sample in graduated cylinder into funnel.
8. Rinse a 10 mL portion of distilled water into funnel, if needed.
9. While waiting for completion of filtration, remove the porcelain dish from the desiccator
and weigh.
10. Transfer filtrate to porcelain dish after sample filtering is complete.
11. Transfer filter to porcelain dish after sample filtering is completed.
12. Weigh sample before and after placing into oven to dry at 103° to 105° C for 1 hr.
13. Later cool sample in the desiccator and weigh.
4.4 Fixed and Volatile Solids Ignited at 550°C
Procedure:
1. Place weighed sample and filter into 550° C muffle oven for 15 minutes.
2. Carefully remove sample and filter from muffle oven and cool in air.
3. Weigh sample and filter after cooling and record data.
**Caution Oven Is HOT!!
