Automatic sampler and automatic sampling method

Abstract

The invention discloses an automatic sampler and a method. The automatic sampler comprises a sampling bottle and a tray; a power device, a driving shaft arranged on the power device and a clamping device capable of clamping and vertically overturning the sampling bottle are arranged in the automatic sampler; the clamping device is movably connected with the driving shaft, can move up and down under the action of the power device and the driving shaft; a contact pin capable of being inserted into the sampling bottle is arranged below the clamping device; the interior of the contact pin is of ahollow structure; two pipelines are arranged at the bottom of the contact pin; one pipeline is connected with a water inlet device, and the other pipeline is connected with a water outlet device; anda vacuum generator is installed on the water outlet device; and the automatic sampler is further provided with a control module. Automatic sampling can be achieved, the concentration of sampled watercan be guaranteed, and meanwhile the sampling amount and the sampling time can be accurately controlled; and the sampled water can stay in the sampling bottle without being sucked into a buffer cavityby setting the vacuum degree.

Description

technical field [0001] The invention relates to the field of sample detection, in particular to an automatic sampler and an automatic sampling method. Background technique [0002] With the advancement of technology, producers often need to test the product to ensure that there is no problem with the quality of the product, which requires sampling the product for sample testing. [0003] At present, traditional pharmaceutical factories need manual operation when sampling purified water and water for injection, which is not only cumbersome but also not accurate enough to control the number and concentration of samples, which urgently needs to improve this sampling method. [0004] People thought of designing an autosampler to solve this problem. However, the current autosampler is very immature and generally includes an inlet pipe and an outlet pipe. The sample water enters the sampler from the inlet pipe, and the excess waste water is discharged from the outlet pipe. , ther...

[0003] At present, traditional pharmaceutical factories need manual operation when sampling purified water and water for injection, which is not only troublesome but also not accurate enough to control the number and concentration of samples, which urgently needs to improve this sampling method

[0004] People thought of designing an autosampler to solve this problem. However, the current autosampler is very immature and generally includes an inlet pipe and an outlet pipe. The sample water enters the sampler from the inlet pipe, and the excess waste water is discharged from the outlet pipe. , there are also many problems in this automatic sampler: the current sampler only realizes automaticity in the sampling process, but it cannot automatically make the sampling bottle to the sampling position, nor can it automatically make the sampling bottle return to its original position. Manual operation is very inconvenient, and at the same time, it cannot accurately control the number and type of sampling. It is not suitable for promotion and use in pharmaceutical factories that require accurate sampling. Pharmaceutical factories can only choose to continue to use manual sampling.
