Description
Technical field
The present invention relates to micro-fluidic chip detection technique field, more particularly to a kind of three joint inspection micrometer of clenbuterol hydrochloride
Fluidic chip.
Background technique
Micro-fluidic chip is the emerging technology that chemistry or biological sample are operated and detected on chip.It is micro-
Fluidic chip can be integrated into the operating units such as the preparation of sample, reaction, separation and detection one several square centimeters of chip
On, by the manipulation and control to fluid in microchannel network, it is automatically performed analytic process.Since microfluidic chip technology has
Sample volume is small, integrated level is high, Yi Shixian automation control and the characteristics of high throughput analysis, so that being given birth on micro-fluidic chip
It is more convenient, quick, low in cost to change the more conventional analysis sample pre-treatments of operation.
Clenbuterol hydrochloride is a kind of drug, rather than a kind of specific substance, is the feed addition for referring to promote lean meat growth
Agent.It is any to promote lean meat growth, inhibit the substance of fat meat growth that can be called " clenbuterol hydrochloride ".It is a kind of adrenal gland class
CNS stimulant.Currently, the substance that can be realized this function is the drug that one kind is called beta-stimulants (β-agonist), than
Such as China cause poisoning Clenbuterol (clenbuterol) and the U.S. allow using Ractopamine/translate Lei Tuoba again
Amine (Ractopamine).In China, usually said " clenbuterol hydrochloride " then refers to clenobuterol hydrochloride.It was once used as drug to use
In treatment bronchial asthma, after since its side effect is too big be banned use.There are also salbutamols for other such similar medicines
(Salbutamol) and Terbutaline (Terbutaline) etc., " lean meat " can equally be played the role of, but to human health damage mistake
Greatly, thus security risk is caused.They are also thus disabled in the whole world.The time that its dosage is big, uses is long, metabolism is slow, institute
It is all very big in the intracorporal residual quantity of pig to arrive listing before butchering.This residual quantity enters human body by food, just makes human body gradually
Gradually it is poisoned, savings poisoning.If one time intake is excessive, will generate abnormal physiology reaction intoxicating phenomenon, it is serious can
Lead to death；Chromatograph test strip is a kind of method of rapid field detection clenbuterol hydrochloride at present.
Chromatograph test strip has been widely used in the fields such as clinical diagnosis, food safety, environment measuring.Detection method packet
Coloration, fluorescence, Magnetic testi etc. are included, depending on the marker in bonding pad, and if quantitative detection, such as fluorescence is needed to be measured
Cleaning solution is added dropwise in liquid after reaction, and removal detection zone is not associated with marker, reduces interference.Operator is needed in routine operation
Be added prepare liquid reaction wait for a period of time after, be manually added cleaning solution, then again with visually or easy detection device into
Row result is read, and the degree of automation is poor, influences detection efficiency.
Therefore, how a kind of clean hygiene, detection three joint inspection micrometer fluidic chip of clenbuterol hydrochloride accurate, easy to operate are provided
The problem of being those skilled in the art's urgent need to resolve.
