For a long time

The routine identification of whether the drug is used is urinary test

But some drug addicts will be based on

Time to stop taking drugs a few days in advance

Even drink plenty of water,

Eat some drugs that have been excreted to accelerate the discharge of drugs

After the regular urine test, suck

This situation has made the police unable to show

With the launch of hair detection technology

Even a hair can be detected accurately

The toxicity of drugs in the body

Is it amazing?

How powerful is hair identification?

On April 1, 2017, in the new "Identification of Drug Addictions" announced and implemented by the Ministry of Public Security, for the first time, drugs detected drugs in hair as a criterion for determining drug addiction. This is because the drug component can exist in hair for a long time (half a year or even longer).

There are many advantages of hair detection, such as long testing, easy to adopt, preserved, repeated sampling, etc. The main thing is that not only the hair, but the body hair of the body is suitable for hair testing. This undoubtedly increases the amplitude of the sampling and is easier to collect.

The hair test needs to be paid attention to the following points:

1. The hair sample is best to collect the rear of the head, cut the hair within 3 cm from the hair roots, and cut it from the root end of the hair.

2. The collection of hair is preferably stored in room temperature, lighting, drying, ventilation, and clean environment to avoid being polluted and affecting the test results.

Better close to actual combat and serve the grassroots level

Hair poison of hair reporting on literature

Laboratory testing technology for system optimization

Further simplify the previous processing process

Shorten the instrument analysis time

Reduce analysis cost

From collecting samples to final issuance

The inspection report only takes 5 hours

Two people use one

Liquid color spectrum spectrum combined instrument

You can analyze more than 100 samples per day
