QCM Flow Cell Kit

The Resonant frequency of quartz changes when material attaches the electrode's surface. This product is capable of super-micro quantitative analysis by using this unique behavior.
 

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


Base line is stable enough as figure in right shows.





Above figure shows result of change in frequency with time by adding :
avidin(2mg/ml), ethanol amine(5mM),
BSA in PBS(1%),
Biotin-Allo A lectin(0.05mg/ml, in 1%BSA),
galactose-carrying polymer(1mg/ml, in 1%BSA),
PBS

 

Quartz Crystal

Thickness of 10MHz quartz is 0.16 mm. To accelerate 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 adhensive layer. We would recommend unpolished quartz if there is possibility that the titanium layer might effect on your experiment. We would like you to note that the gold layer on unpolished quarts peals off easier than polished one because it does not have adhensive layer.
