QCM Flow Cell Kit

QCM flow cell kit -- super-micro quantitative analysis

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.

QCM flow cell kit -- Stability of base line






solution: PBS with 2 mM Dithiodipropionic acid
a: stationary state
Flow rate: b:85, c:110, d:140, e:160, f:190 µl/min


Baseline is stable enough as shown in figure.




IDA Electrode Connecting Cable kit
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),
PBS

Quartz Crystal

Structure_Quartz

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 Å 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.
