Abstract
The present invention is to detect leakage of fluid from a channel in a microreactor certainly at an early stage. A chemical reactor has a microreactor with a pump for sending first, second solutions, and a channel for mixing and reacting the first, second solutions. The solution sending amount of the first, second solutions to be supplied to the microreactor is controlled by a pump controlling device. The microreactor has a first substrate with a channel and a second substrate to be bonded airtightly with the first substrate. A leak detecting channel is formed in the vicinity of the channel in the first substrate.
Claims7
A substance manufacturing apparatus having a first substrate having a channel for mixing and allowing passage of first and second solutions, and a second substrate mounted airtightly on the first substrate, wherein a leak detecting channel for detecting leakage of the first, second solutions or a reaction product solution from the channel is formed in the vicinity of the channel formed in the first substrate.
The substance manufacturing apparatus according to claim, wherein a pressure detecting means for detecting the pressure of the leak detecting channel, and a pressure regulator for judging leakage of the solution by comparing the pressure with a predetermined value are provided, and the pressure regulator maintains the leak detecting channel in a negative pressure.
A chemical reactor comprising a pump for sending first and second solutions, a pump control device for controlling the sending amount of the first and second solutions to be sent by the pump, and a microreactor to have supply of the first and second solutions, having a channel for mixing and reacting the first and second solutions, wherein the microreactor has a first substrate with the channel and a second substrate to be bonded airtightly with the first substrate, a leak detecting channel with gas sealed by a negative pressure provided in the vicinity of the channel formed in the first substrate, a pressure detecting means for detecting the pressure of the leak detecting channel, and a pressure regulator for judging leakage of the first and second solutions or a reaction product solution by comparing the pressure detected by the pressure detecting means with a predetermined value.
