Abstract
The invention discloses a pen-type quartz crystal oscillation detection device. The pen-type quartz crystal oscillation detection device is used for detection of trace substances in a solution and comprises a sensor chip, a cannula, a core, a lead, a lead sheath, an electrode lead and a spring electrode. The sensor chip is fixed to the bottom of the cannula. An upper part of the core is a hollow tube. The periphery of the upper part of the core is provided with a step. A core part below the step is inserted into the cannula and is positioned at the step. A middle-lower part of the core is provided with a thread hole and two installation holes. The spring electrode and the electrode lead are installed in the two installation holes. The electrode lead passes through the thread hole, is connected to the lead and is led out from the lead sheath. Two electrode contacts on the spring electrode and the sensor chip are in an elastic contact connection relationship. The pen-type quartz crystal oscillation detection device can be inserted into a sample solution needing to be detected conveniently and carry out detection, and has wide applicability.
