Ah, sawdust, sawdust, tops, skin and truncated heads, harvesting residues and processing residues such as nutshell and kernels, papermaking waste, and discarded wood)
Energy forest.
[GB/T 30366-2013, Definition 2.1.3]
3.2
Sampledivision sampledivision
The sample or sample is divided into representative, separate part of the sample preparation process.
[GB/T 21923-2008, Definition 3.82]
4 sample processing
The main purpose of sample processing is to process the sample into analytical samples that represent the characteristics of the original sample by drying, crushing, screening and other steps.
The principle of sample handling is that the composition and quality characteristics of the original sample do not change during sample processing.
5 Reagents and materials
5.1 acetone, analytical grade.
5.2 Dry ice (solid carbon dioxide). Purity not less than 90%.
