  • A The temperature stability depends on variations in how the ambient temperature affects the warming or cooling of the chamber.
  • B Smallest sample volume to pick up and dispense. Note that the smallest volume needed for measurement is 50 µl.
  • C Data from one sensor in single frequency mode. One data point collected every 5 seconds. The Sauerbrey relation is assumed to be valid.
  • E Data from multiple frequency modes (all harmonics). Four data points are collected within 1 second. The Sauerbrey relation is assumed to be valid.
  • F Data from all sensors in multiple frequency modes (all harmonics) are collected within 1 second. The Sauerbrey relation is assumed to be valid
