QCM Flow Cell Kit
Also available EQCM flow cell kit
The Resonance frequency of quartz changes when material attaches
to the electrode's surface.
This product is capable of super-micro quantitative analysis by using this unique behavior.
solution: PBS with 2 mM Dithiodipropionic acid
a: stationary state
Flow rate: b:85, c:110, d:140, e:160, f:190 Ál/min
Baseline is stable enough as shown in figure.
Above figure shows result of change in frequency with time by adding :
avidin (2 mg/ml), ethanolamine (5 mM),
BSA in PBS (1%),
Biotin-Allo A lectin (0.05 mg/ml, in 1% BSA),
galactose-carrying polymer (1 mg/ml, in 1% BSA),
Thickness of 10 MHz quartz is 0.16 mm. Accelerating the
oscillation frequency means to make the quartz thinner and delicate.
Resolution and easiness to care for should be taken into the
consideration. We can offer two surface conditions of quartz -
Polished and Unpolished. Polished one has a 100 ┼ thickness of gold
layer on a titanium adhesive layer. We would recommend the
unpolished quartz if there is a possibility that the titanium layer
might effect on your experiment. We would like you to note that the
gold layer on the unpolished quartz peels off easier than the
polished one because it does not have adhesive layer.
