EQCM Flow Cell
The quartz crystal microbalance (QCM) technique under electrochemical frequency, analysis
of electrode can be measured by the gold quartz crystal electrode. This technique is very
useful to determine many compounds such as metal proteins, metal ions and thiol-conjugated
oligonucleotides.
The construction for EQCM flow cell is simple. The gold quartz crystal electrode is sandwiched
between two blocks as shown below.
The two blocks of the EQCM Flow cell are constructed using PEEK. It gives a high resistivity for chemical compounds.
As well as QCM, these cell is reversible. With a inverted position of the blocks, it is possible to change
from flow to static measurement.
