The Chuangxing Model RDTD19H On-site Trace Hair Drug Detector (hereinafter referred to as the Hair Drug Detector), independently developed and manufactured by Jinan Chuangxingweier Electronic Technology Co., Ltd., has been put into practical use in anti-drug operations and criminal investigation work of public security organs. It has further strengthened the screening and control of drug users, leaving them nowhere to hide.
Police officers from a grassroots police station in Dongying City lawfully summoned a drug-related suspect Wang to the station for a urine test. However, all test results for methamphetamine (commonly known as ice), morphine and ketamine (commonly known as K powder) came back negative. At the sight of the results, the suspect sighed with relief, insisting that he had not taken any drugs.
Urine tests have a short detection window, and the results are not entirely accurate for those who have abstained from drug use for 3 to 7 days. Investigating officers immediately collected a hair sample from Wang and sent it to the Criminal Investigation Detachment of Baotou Public Security Bureau for testing. The hair drug detector confirmed a positive result for methamphetamine in his hair. With the support of this cutting-edge technology, the police finally ascertained conclusive evidence of Wang's drug use and determined that he might have connections with a local methamphetamine ring.
Our company's independently developed and manufactured Chuangxing Model RDTD19H Hair Drug Detector adopts an advanced quantum dot fluorescence method. Featuring simple operation, easy portability and convenient sampling, it enables non-invasive hair testing that eliminates the risk of pathogen infection, and is adaptable to various testing environments. The entire hair testing process takes no more than 10 minutes, which greatly boosts the work efficiency of grassroots police officers. The detector can rapidly and accurately detect three common drugs in hair – morphine, methamphetamine (ice) and ketamine (K powder) – and print out qualitative and quantitative test results along with corresponding numerical values, serving as a basis for on-site inspection and disposal by anti-drug police officers. Moreover, it is not limited to testing scalp hair from suspected drug users: for bald suspects, it can conduct tests on body hair such as armpit hair and leg hair, enabling accurate determination of whether a suspect has taken drugs within a certain period. With a maximum drug detection window of 3 to 6 months and highly accurate test results, the instrument has been well received by users, and all its performance indicators rank among the top in China.
