  • AThe temperature stability depends on variations in how the ambient temperature affects the warming or cooling of the chamber.
  • B最小的样品卷接和分发。没有te that the smallest volume needed for measurement is 50 µl.
  • CData from one sensor in single frequency mode. One data point collected every 5 seconds. The Sauerbrey relation is assumed to be valid.
  • EData from multiple frequency modes (all harmonics). Four data points are collected within 1 second. The Sauerbrey relation is assumed to be valid.
  • FData from all sensors in multiple frequency modes (all harmonics) are collected within 1 second. The Sauerbrey relation is assumed to be valid
