Example Embodiment
[0030] Example 1
[0031] A pretreatment method for detecting drugs in human hair, including the following steps:
[0032] S1. Take a hair sample, and cut the hair sample into small pieces with a length of 3mm;
[0033] S2. Place the hair sample cut in step S1 in a grinding tube, add the hair lysis solution, and pulverize it by a hair pulverizer;
[0034] S3. Take out the hair sample crushed in step S2, complete the pre-processing for detecting drugs in human hair, and then use it for drug testing.
[0035] Furthermore, in step S2, when pulverizing, grinding beads are also added to the grinding tube.
[0036] Furthermore, the grinding beads are zircon and quartz sand. The hair pulverizer uses a grinding tube for grinding. Zircon and quartz sand of different thicknesses are added to the grinding tube, so that the hair can be quickly crushed during the grinding process.
[0037] Further, in step S2, the temperature is maintained at 4°C during the pulverization by the hair pulverizer. Keep...

[0046] Example 2
[0047] A pretreatment method for detecting drugs in human hair, including the following steps:
[0048] S1. Take a hair sample and cut the hair sample into small pieces with a length of 5mm;
[0049] S2. Place the hair sample cut in step S1 in a grinding tube, add the hair lysis solution, and pulverize it by a hair pulverizer;
[0050] S3. Take out the hair sample crushed in step S2, complete the pre-processing for detecting drugs in human hair, and then use it for drug testing.
[0051] Furthermore, in step S2, when pulverizing, grinding beads are also added to the grinding tube.
[0052] Furthermore, the grinding beads are zircon. The hair pulverizer uses a grinding tube for pulverization. Zircons of different thicknesses are added to the grinding tube to quickly pulverize the hair during the pulverization process.
[0053] Further, in step S2, the temperature is maintained at 4°C during the pulverization by the hair pulverizer. Keeping low temperature during the cr...

[0062] Example 3
[0063] A pretreatment method for detecting drugs in human hair, including the following steps:
[0064] S1. Take a hair sample and cut the hair sample into small pieces with a length of 4mm;
[0065] S2. Place the hair sample cut in step S1 in a grinding tube, add the hair lysis solution, and pulverize it by a hair pulverizer;
[0066] S3. Take out the hair sample crushed in step S2, complete the pre-processing for detecting drugs in human hair, and then use it for drug testing.
[0067] Furthermore, in step S2, when pulverizing, grinding beads are also added to the grinding tube.
[0068] Furthermore, the grinding beads are quartz sand. The hair pulverizer uses a grinding tube for pulverization, and the grinding tube is filled with quartz sand of different thicknesses, so that the hair can be quickly pulverized during the pulverization process.
[0069] Further, in step S2, the temperature is maintained at 4°C during the pulverization by the hair pulverizer. Keeping ...
