Page 22: Avoid Bumping
Make sure to treat the blank in the same way as the samples. If you have an infrared digestion device (e. g. behr InKjel) too, the easiest way to digest high-protein samples will be the infrared digestion. In an infrared digestion, the samples reach digestion temperature very quickly so the foam will collapse soon. -
