When a sample is dry ashed, a fine residue (ash) is often formed. The small particles in the residue are resuspended readily by any air flow over the sample. Air flows are generated by changes in temperature (e.g., opening the furnace while it is hot) or by passing a stream of gas over the sample during heating to assist in combustion.

As small samples (100 mg or <20 ml) are difficult to recover from a standard mortar and pestle, the CryoGrinder serves as an alternative. The CryoGrinder is a miniature mortar shaped as a small well and a tightly fitting pestle. The CryoGrinder is prechilled, then samples are added to the well and ground by a handheld cordless screwdriver.

The cryogenic grinding of carob pulp resulted in powder samples with a small particle size compared to vibratory ground carob powder, particularly those ground for 4 min. This is also proportional to the colour of cryogenically ground carob powder (lighter, less red, and less yellow) and its higher antioxidant capacity.
