Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below.

[0034] The preparation method of the morphine urine detection kit quality control test dish comprises the following steps:

[0035] (1) Take negative urine and keep it for later use;

[0036] (2) Urine preparation for morphine threshold detection

[0037] (21) Weigh an appropriate amount of morphine standard substance in a 5ml volumetric flask, prepare a 1mg / ml stock solution with methanol, and then store the stock solution at minus 20°C;

[0038] (22) Take 100 μl of the stock solution obtained in step (21), add 9900 μl of negative urine from step (1) to it for dilution, and prepare an intermediate solution;

[0039] (23) Dilute the intermediate solution obtained in step (22) with negative urine into different concentrations of urine to be tested, and store all the urine to be tested at minus 20°C, wherein:

[0040] The urine to be tested with different concentrations includes the firs...

Abstract

The invention, which belongs to the field of poison detection, particularly relates to a preparation method of a quality control test tray for a morphine urine test kit. The preparation method comprises the following steps: (1), taking negative urine for standby application; (2), preparing morphine threshold detection urine; (3), preparing anti-interference test urine; (4), freezing and drying theprepared urine; and (5), packaging frozen and dried samples obtained in the step (4) into mutually spaced space of a quality control test tray respectively to obtain a quality control test tray for amorphine urine examination test kit. The preparation method has the following beneficial effects: firstly, the preparation method is simple; secondly, the prepared quality control test tray is easy to store, transport or carry; and thirdly, the efficiency of evaluating the test liquid test kit is greatly improved.

Description

technical field [0001] The invention belongs to the field of poison detection, and in particular relates to a preparation method of a quality control test disc of a morphine urine detection kit. Background technique [0002] In 1806, the German chemist Zeltina first isolated it from opium and named it morphine after Morpheus, the Greek god of dreams. Its derivative, morphine hydrochloride, is a commonly used anesthetic in clinical practice. It has a strong analgesic effect, and its analgesic effect has good selectivity. It is mostly used for severe pain caused by trauma, surgery, burns, etc., and it is also used for myocardial Angina pectoris caused by infarction can also be used as an analgesic, antitussive and antidiarrheal agent. But its biggest disadvantage is that it is easy to become addicted. This makes long-term smokers have serious dependence on morphine both physically and psychologically, resulting in serious drug addiction, thus causing great harm to themselves...
