To assist the burning of a moist sample:
 |
Use the normal method with the cotton thread touching the sample. |
 |
Use the spiking method with Benzoic Acid |
How To Measure Samples With High Moisture
The moisture content of a solid sample affects the result directly: a 1% difference in moisture will make a 1% difference in the result. The CAL3K can compensate for the moisture content but the actual moisture must be established before the determination.
The actual ignition method needs to be determined experimentally.
The ignition of the moist sample depends on:
|
Use the normal method with the cotton thread touching the sample. |
|
Use the spiking method with Benzoic Acid |
This video will show you the correct way to attach the firing cotton.
Watch VideoThe suggestions are not very helpful if the moisture content varies then the result shall vary as well and the sample may not ignite.
Experiment and see what works for you.
