Abstract
The invention discloses a quartz crystal microbalance detection cell and belongs to the field of scientific detection instruments. The quartz crystal microbalance detection cell is used for detection of a liquid-phase sample. The quartz crystal microbalance detection cell is composed of a flange-shaped housing and quartz crystal plates in the flange-shaped housing. A flange-shaped housing inner-wall part close to a flange end is provided with a raised step. The quartz crystal plates are put on the raised step. Diameters of the quartz crystal plates gaplessly match with an inner diameter of the flange-shaped housing. The flange-shaped housing is made of an elastic material. Two electrode contacts of each one of the quartz crystal plates are in the same level. The quartz crystal microbalance detection cell can effectively avoid installation stress influences on the quartz crystal plates in an oscillation direction, has a simple structure and can be dismounted, assembled or replaced flexibly.
Description
Technical field
The present invention relates to a kind of detection cell of quartz crystal microbalance, the detection cell of quartz crystal slice namely is housed, be used for the liquid phase sample and detect.
Background technology
QCM (Quartz Crystal Microbalance) (QCM) is a kind of novel sensor measuring technique.The principle that it utilizes the frequency change of quartz vibrator to be directly proportional with the mass change of plane of crystal, but the mass change of detecting electrode surface n g level and solution viscosity, density, the isoparametric variation of modified membrane viscoelasticity, have highly sensitive, the characteristics such as can measure in real time, can be used as the means that on-line tracing monitoring microprocess changes, in the exploratory development of microprocess and the mechanism of action is carried out in the aspects such as modern chemistry, material science, biology and medical science, present good development prospect.
For QCM (Quartz Crystal Microbalance) (QCM) detecting instrument of liquid phase detected object, its core component is the detection cell that quartz crystal slice is housed.Because the characteristic that has of quartz crystal slice, so that its mounting design in detection cell has higher requirement, that is: in the situation of strict sealing and insulation, avoid the additional installation stress of its orientation of oscillation as far as possible.Prior art adopts O type O-ring seal or usually in measures such as quartz crystal slice outer rim heap glue, can solve sealing and Insulation Problems, but can not well solve additional installation stress problem, although perhaps consider simultaneously installation stress problem, its design exists complex structure, the flexible drawback of dismounting or replacing.For example Chinese patent application number is 200910065451.2 " a kind of quartz crystal sensor detecting tank ", on April 14th, 2004 disclosed " CN1489825 chip quartz oscillator and liquid-phase sensor " and " CN2328998 electrochemical insite quartz crystal micro balance detection pool " that on June 5th, 1999, bulletin was authorized.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of detection cell of quartz crystal microbalance is provided, be intended to avoid quartz crystal slice to be installed in the installation stress of suffered orientation of oscillation in the detection cell, and flexibly dismounting or replacing.
For solving the problems of the technologies described above, the present invention takes following technical scheme, a kind of detection cell of quartz crystal microbalance, consisted of by the in-built quartz crystal slice of flange-like housing, near flange flange end place raised step is set in the flange-like inner walls, quartz crystal slice places this step place, the quartz crystal slice diameter cooperates with flange-like housing internal diameter zero stand-off, be in tightening state to reach sealing effectiveness, the flange-like housing adopts resilient material, quartz crystal slice adopts two electrode contacts to be positioned at the quartz crystal slice of one side, and two electrode contacts are towards the flange flange end, and flange flange is convenient to be connected flexibly with contact conductor mechanism as buckle.
For quartz crystal slice is cooperated with fit sealing with flange-like inner walls zero stand-off, can take the different structure form, one, with the heating of flange-like housing, cooling gets final product after installing before installing; Its two, first quartz crystal slice is placed in step place in the flange-like housing, again with a rigid pipe cuff at flange-like housing outer wall, the outer wall interference fit of the inwall of described rigidity pipe collar and flange-like housing; Its three, make it and the flange-like inner walls forms resilient tight fit at quartz crystal slice outer rim suit O RunddichtringO.
The beneficial effect of detection cell of quartz crystal microbalance provided by the invention is, can effectively avoid quartz crystal slice to be installed in the installation stress of suffered orientation of oscillation in the detection cell and simple in structure, flexibly dismounting or replacing.
