Procedure. If using the SMART 6 system, use one of the following four different sample spread
techniques, based on the viscosity and moisture content of the sample:
Pipette – for highly absorbent, high moisture samples (>85% moisture), simply pipette the
sample into the center of the top sample pad. The sample will fully absorb into the pad
within a few seconds, after which the analysis can begin.
Example- milk
Pipette, cover, and press – for slightly less absorbent products that still have a high moisture
content, pipette the product into the center of the top sample pad, then cover the sample
with the bottom sample pad to fully cover the product. Then gently use the Sample Press to
spread the sample thinly and evenly between the two pads
Example- cream
Mound, cover, and press – for solid and semi-solid products, use a spatula to place the
correct sample weight on the center of the top glass fiber sample pad while it is still on the
balance pan. Then cover with the bottom sample pad and use the Sample Press to spread
the product thinly and evenly. Ensure no product has pressed out of the two sample pads.
Example- meat or cheese
Powder – for low moisture samples in granular or powder form, the sample needs to be
spread thinly and evenly for the most accurate and rapid analysis. This can be performed
with a CEM template, which allows the user to easily add the exact same amount of product
in the exact same form every time. The user can also mound the product on the pad and use
the spatula to spread it evenly.
Example- whey powder
